NTS0102 Dual supply translating transceiver; open drain; auto direction sensing Rev. 2 — 11 April 2011 Product data sheet 1. General description The NTS0102 is a 2-bit, dual supply translating transceiver with auto direction sensing, that enables bidirectional voltage level translation. It features two 2-bit input-output ports (An and Bn), one output enable input (OE) and two supply pins (VCC(A) and VCC(B)). VCC(A) can be supplied at any voltage between 1.65 V and 3.6 V and VCC(B) can be supplied at any voltage between 2.3 V and 5.5 V, making the device suitable for translating between any of the voltage nodes (1.8 V, 2.5 V, 3.3 V and 5.0 V). Pins An and OE are referenced to VCC(A) and pins Bn are referenced to VCC(B). A LOW level at pin OE causes the outputs to assume a high-impedance OFF-state. This device is fully specified for partial power-down applications using IOFF. The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down. 2. Features and benefits Wide supply voltage range: VCC(A): 1.65 V to 3.6 V and VCC(B): 2.3 V to 5.5 V Maximum data rates: Push-pull: 50 Mbps IOFF circuitry provides partial Power-down mode operation Inputs accept voltages up to 5.5 V ESD protection: HBM JESD22-A114E Class 2 exceeds 2500 V for A port HBM JESD22-A114E Class 3B exceeds 8000 V for B port MM JESD22-A115-A exceeds 200 V CDM JESD22-C101E exceeds 1500 V Latch-up performance exceeds 100 mA per JESD 78B Class II Multiple package options Specified from −40 °C to +85 °C and −40 °C to +125 °C 3.

Application information 14.1 Applications Voltage level-translation applications. The NTS0102 can be used in point-to-point applications to interface between devices or systems operating at different supply voltages. The device is primarily targeted at I2C or 1-wire which use open-drain drivers, it may also be used in applications where push-pull drivers are connected to the ports, however the NTB0102 may be more suitable. 1.8 V 3.3 V 0.1 μF 1.8 V SYSTEM CONTROLLER VCC(A) VCC(B) 3.3 V SYSTEM 0.1 μF 1 μF OE NTS0102 A1 B1 A2 B2 DATA DATA 001aam491 Fig 9.

Architecture of NTS0102 I/O cell (one channel) The NTS0102 is a "switch" type voltage translator, it employs two key circuits to enable voltage translation: 1. A pass-gate transistor (N-channel) that ties the ports together. 2. An output edge-rate accelerator that detects and accelerates rising edges on the I/O pins.

All rights reserved. 14 of 25 NTS0102 NXP Semiconductors Dual supply translating transceiver; open drain; auto direction sensing The gate bias voltage of the pass gate transistor (T3) is set at approximately one threshold voltage above the VCC level of the low-voltage side. During a LOW-to-HIGH transition the output one-shot accelerates the output transition by switching on the PMOS transistors (T1, T2) bypassing the 10 kΩ pull-up resistors and increasing current drive capability. The one-shot is activated once the input transition reaches approximately VCCI/2; it is de-activated approximately 50 ns after the output reaches VCCO/2. During the acceleration time the driver output resistance is between approximately 50 Ω and 70 Ω. To avoid signal contention and minimize dynamic ICC, the user should wait for the one-shot circuit to turn-off before applying a signal in the opposite direction. Pull-up resistors are included in the device for DC current sourcing capability. 14.3 Input driver requirements As the NTS0102 is a switch type translator, properties of the input driver directly effect the output signal. The external open-drain or push-pull driver applied to an I/O determines the static current sinking capability of the system; the max data rate, HIGH-to-LOW output transition time (tTHL) and propagation delay (tPHL) are dependent upon the output impedance and edge-rate of the external driver. The limits provided for these parameters in the datasheet assume a driver with output impedance below 50 Ω is used. 14.4 Output load considerations The maximum lumped capacitive load that can be driven is dependant upon the one-shot pulse duration. In cases with very heavy capacitive loading there is a risk that the output will not reach the positive rail within the one-shot pulse duration. To avoid excessive capacitive loading and to ensure correct triggering of the one-shot it's recommended to use short trace lengths and low capacitance connectors on NTS0102 PCB layouts. To ensure low impedance termination and avoid output signal oscillations and one-shot re-triggering, the length of the PCB trace should be such that the round trip delay of any reflection is within the one-shot pulse duration (approximately 50 ns). 14.5 Power up During operation VCC(A) must never be higher than VCC(B), however during power-up VCC(A) ≥ VCC(B) does not damage the device, so either power supply can be ramped up first. There is no special power-up sequencing required. The NTS0102 includes circuitry that disables all output ports when either VCC(A) or VCC(B) is switched off. 14.6 Enable and disable An output enable input (OE) is used to disable the device. Setting OE = LOW causes all I/Os to assume the high-impedance OFF-state. The disable time (tdis with no external load) indicates the delay between when OE goes LOW and when outputs actually become disabled. The enable time (ten) indicates the amount of time the user must allow for one one-shot circuitry to become operational after OE is taken HIGH. To ensure the high-impedance OFF-state during power-up or power-down, pin OE should be tied to GND through a pull-down resistor, the minimum value of the resistor is determined by the current-sourcing capability of the driver.

All rights reserved. 15 of 25 NTS0102 NXP Semiconductors Dual supply translating transceiver; open drain; auto direction sensing 14.7 Pull-up or pull-down resistors on I/Os lines Each A port I/O has an internal 10 kΩ pull-up resistor to VCC(A), and each B port I/O has an internal 10 kΩ pull-up resistor to VCC(B). If a smaller value of pull-up resistor is required, an external resistor must be added parallel to the internal 10 kΩ, this will effect the VOL level. When OE goes LOW the internal pull-ups of the NTS0102 are disabled. NTS0102 Product data sheet All information provided in this document is subject to legal disclaimers.
