NVT2008; NVT2010 Bidirectional voltage-level translator for open-drain and push-pull applications Rev. 3 — 27 January 2014 Product data sheet 1. General description The NVT2008/NVT2010 are bidirectional voltage level translators operational from 1.0 V to 3.6 V (Vref(A)) and 1.8 V to 5.5 V (Vref(B)), which allow bidirectional voltage translations between 1.0 V and 5 V without the need for a direction pin in open-drain or push-pull applications. Bit widths of 8-bit to 10-bit are offered for level translation application with transmission speeds < 33 MHz for an open-drain system with a 50 pF capacitance and a pull-up of 197 . When the An or Bn port is LOW, the clamp is in the ON-state and a low resistance connection exists between the An and Bn ports. The low ON-state resistance (Ron) of the switch allows connections to be made with minimal propagation delay. Assuming the higher voltage is on the Bn port when the Bn port is HIGH, the voltage on the An port is limited to the voltage set by VREFA. When the An port is HIGH, the Bn port is pulled to the drain pull-up supply voltage (Vpu(D)) by the pull-up resistors. This functionality allows a seamless translation between higher and lower voltages selected by the user without the need for directional control. When EN is HIGH, the translator switch is on, and the An I/O are connected to the Bn I/O, respectively, allowing bidirectional data flow between ports. When EN is LOW, the translator switch is off, and a high-impedance state exists between ports. The EN input circuit is designed to be supplied by Vref(B). To ensure the high-impedance state during power-up or power-down, EN must be LOW. All channels have the same electrical characteristics and there is minimal deviation from one output to another in voltage or propagation delay. This is a benefit over discrete transistor voltage translation solutions, since the fabrication of the switch is symmetrical. The translator provides excellent ESD protection to lower voltage devices, and at the same time protects less ESD-resistant devices. 2.

Application design-in information The NVT2008/10 can be used in level translation applications for interfacing devices or systems operating at different interface voltages with one another. The NVT2008/10 is ideal for use in applications where an open-drain driver is connected to the data I/Os. The NVT2008/10 can also be used in applications where a push-pull driver is connected to the data I/Os. 7.1 Enable and disable The NVT20xx has an EN input that is used to disable the device by setting EN LOW, which places all I/Os in the high-impedance state.

Bidirectional translation to multiple higher voltage levels 7.2 Bidirectional translation For the bidirectional clamping configuration (higher voltage to lower voltage or lower voltage to higher voltage), the EN input must be connected to VREFB and both pins pulled to HIGH side Vpu(D) through a pull-up resistor (typically 200 k). This allows VREFB to regulate the EN input. A filter capacitor on VREFB is recommended. The master output driver can be totem pole or open-drain (pull-up resistors may be required) and the slave device output can be totem pole or open-drain (pull-up resistors are required to pull the Bn outputs to Vpu(D)). However, if either output is totem-pole, data must be unidirectional or the outputs must be 3-stateable and be controlled by some direction-control mechanism to prevent HIGH-to-LOW contentions in either direction. If both outputs are open-drain, no direction control is needed. The reference supply voltage (Vref(A)) is connected to the processor core power supply voltage. When VREFB is connected through a 200 k resistor to a 3.3 V to 5.5 V Vpu(D) power supply, and Vref(A) is set between 1.0 V and (Vpu(D) 1 V), the output of each An has a maximum output voltage equal to VREFA, and the output of each Bn has a maximum output voltage equal to Vpu(D).

One of the channel transistors is used as a second reference transistor with its B side connected to a voltage supply that is at least 1 V (and preferably 1.5 V) above the maximum possible for either Vpu(A) or Vpu(B). Then if either pull-up voltage is at 0 V, the channels are disabled, and otherwise the channels are biased such that they turn OFF at the lower pull-up voltage, and if the two pull-up voltages are equal, the channel is biased such that it just turns OFF at the common pull-up voltage.

Fig 10. Bidirectional level shifting between two different power domains 7.4 How to size pull-up resistor value Sizing the pull-up resistor on an open-drain bus is specific to the individual application and is dependent on the following driver characteristics: • • • • The driver sink current The VOL of driver The VIL of the driver Frequency of operation The following tables can be used to estimate the pull-up resistor value in different use cases so that the minimum resistance for the pull-up resistor can be found.

All rights reserved. 9 of 33 NVT2008; NVT2010 NXP Semiconductors Bidirectional voltage-level translator Table 6, Table 7 and Table 8 contain suggested minimum values of pull-up resistors for the PCA9306 and NVT20xx devices with typical voltage translation levels and drive currents. The calculated values assume that both drive currents are the same. VOL = VIL = 0.1 VCC and accounts for a 5 % VCC tolerance of the supplies, 1 % resistor values. It should be noted that the resistor chosen in the final application should be equal to or larger than the values shown in Table 6, Table 7 and Table 8 to ensure that the pass voltage is less than 10 % of the VCC voltage, and the external driver should be able to sink the total current from both pull-up resistors. When selecting the minimum resistor value in Table 6, Table 7 or Table 8, the drive current strength that should be chosen should be the lowest drive current seen in the application and account for any drive strength current scaling with output voltage. For the GTL devices, the resistance table should be recalculated to account for the difference in ON resistance and bias voltage limitations between VCC(B) and VCC(A). Table 6.

See Equation 1 as an example of the maximum frequency. The rise and fall times are shown in Figure 11. 1 f max = ------------------------------------------------------------------------------------------------------------t LOW min + t HIGH min + t r actual + t f actual tr(actual) VIH VCC (1) tf(actual) tHIGH(min) 0.9 × VCC tLOW(min) VIL VOL GND 0.1 × VCC 1 / fmax 002aag912 Fig 11. An example waveform for maximum frequency The rise and fall times are dependent upon translation voltages, the drive strength, the total node capacitance (CL(tot)) and the pull-up resistors (RPU) that are present on the bus. The node capacitance is the addition of the PCB trace capacitance and the device capacitance that exists on the bus. Because of the dependency of the external components, PCB layout and the different device operating states the calculation of rise and fall times is complex and has several inflection points along the curve. The main component of the rise and fall times is the RC time constant of the bus line when the device is in its two primary operating states: when device is in the ON state and it is low-impedance, the other is when the device is OFF isolating the A-side from the B-side. A description of the fall time applied to either An or Bn output going from HIGH to LOW is as follows. Whichever side is asserted first, the B-side down must discharge to the V CC(A) voltage. The time is determined by the pull-up resistor, pull-down driver strength and the NVT2008_NVT2010 Product data sheet All information provided in this document is subject to legal disclaimers.

As the level moves below the VCC(A) voltage, the channel resistance drops so that both A and B sides equal. The capacitance on both sides is connected to form the total capacitance and the pull-up resistors on both sides combine to the parallel equivalent resistance. The Ron of the device is small compared to the pull-up resistor values, so its effect on the pull-up resistance can be neglected and the fall is determined by the driver pulling the combined capacitance and pull-up resistor currents. An estimation of the actual fall time seen by the device is equal to the time it takes for the B-side to fall to the VCC(A) voltage and the time it takes for both sides to fall from the VCC(A) voltage to the VIL level. A description of the rise time applied to either An or Bn output going from LOW to HIGH is as follows. When the signal level is LOW, the Ron is at its minimum, so the A and B sides are essentially one node. They will rise together with an RC time constant that is the sum of all the capacitance from both sides and the parallel of the resistance from both sides. As the signal approaches the VCC(A) voltage, the channel resistance goes up and the waveforms separate, with the B side finishing its rise with the RC time constant of the B side. The rise to VCC(A) is essentially the same for both sides. There are some basic guidelines to follow that will help maximize the performance of the device: • Keep trace length to a minimum by placing the NVT device close to the processor. • The signal round trip time on trace should be shorter than the rise or fall time of signal to reduce reflections. • The faster the edge of the signal, the higher the chance for ringing. • The higher drive strength controlled by the pull-up resistor (up to 15 mA), the higher the frequency the device can use.

Performance curves tPLH up-translation is typically dominated by the RC time constant, i.e., CL(tot) RPU = 50 pF 197 = 9.85 ns, but the Ron CL(tot) = 50 pF 5 = 0.250 ns. tPHL is typically dominated by the external pull-down driver + Ron, which is typically small compared to the tPLH in an up-translation case. Enable/disable times are dominated by the RC time constant on the EN pin since the transistor turn off is on the order of ns, but the enable RC is on the order of ms. Fall time is dominated by the external pull-down driver with only a slight Ron addition. Rise time is dominated by the RPU CL. Skew time within the part is virtually non-existent, dominated by the difference in bond wire lengths, which is typically small compared to the board-level routing differences. Maximum data rate is dominated by the system capacitance and pull-up resistors. 002aaf701 0.6 tPD (ns) (1) (3) (2) 0.4 002aaf702 3 tPD (ns) (1) (2) 2 (4) (5) 0.2 1 0 0 0 20 40 60 80 100 0 20 40 60 80 C (pF) 100 C (pF) (1) VI(EN) = 1.5 V; IO = 64 mA; VI = 0 V.

Soldering of SMD packages This text provides a very brief insight into a complex technology. A more in-depth account of soldering ICs can be found in Application Note AN10365 “Surface mount reflow soldering description”. 14.1 Introduction to soldering Soldering is one of the most common methods through which packages are attached to Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both the mechanical and the electrical connection. There is no single soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high densities that come with increased miniaturization. 14.2 Wave and reflow soldering Wave soldering is a joining technology in which the joints are made by solder coming from a standing wave of liquid solder. The wave soldering process is suitable for the following: • Through-hole components • Leaded or leadless SMDs, which are glued to the surface of the printed circuit board Not all SMDs can be wave soldered. Packages with solder balls, and some leadless packages which have solder lands underneath the body, cannot be wave soldered. Also, leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered, due to an increased probability of bridging. The reflow soldering process involves applying solder paste to a board, followed by component placement and exposure to a temperature profile. Leaded packages, packages with solder balls, and leadless packages are all reflow solderable. Key characteristics in both wave and reflow soldering are: • • • • • • Board specifications, including the board finish, solder masks and vias Package footprints, including solder thieves and orientation The moisture sensitivity level of the packages Package placement Inspection and repair Lead-free soldering versus SnPb soldering 14.3 Wave soldering Key characteristics in wave soldering are: • Process issues, such as application of adhesive and flux, clinching of leads, board transport, the solder wave parameters, and the time during which components are exposed to the wave • Solder bath specifications, including temperature and impurities NVT2008_NVT2010 Product data sheet All information provided in this document is subject to legal disclaimers.

All rights reserved. 22 of 33 NVT2008; NVT2010 NXP Semiconductors Bidirectional voltage-level translator 14.4 Reflow soldering Key characteristics in reflow soldering are: • Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to higher minimum peak temperatures (see Figure 22) than a SnPb process, thus reducing the process window • Solder paste printing issues including smearing, release, and adjusting the process window for a mix of large and small components on one board • Reflow temperature profile; this profile includes preheat, reflow (in which the board is heated to the peak temperature) and cooling down. It is imperative that the peak temperature is high enough for the solder to make reliable solder joints (a solder paste characteristic). In addition, the peak temperature must be low enough that the packages and/or boards are not damaged. The peak temperature of the package depends on package thickness and volume and is classified in accordance with Table 13 and 14 Table 13. SnPb eutectic process (from J-STD-020D) Package thickness (mm) Package reflow temperature (C) Volume (mm3) < 350 350 < 2.5 235 220 2.5 220 220 Table 14.

Studies have shown that small packages reach higher temperatures during reflow soldering, see Figure 22.
