DATASHEET ISL55100B FN6229 Rev 2.00 December 4, 2014 Quad 18V Pin Electronics Driver/Window Comparator The ISL55100B is a Quad pin driver and window comparator fabricated in a wide voltage CMOS process. It is designed specifically for Test During Burn-In (TDBI) applications, where cost, functional density and power are all at a premium. Features This IC incorporates four channels of programmable drivers and window comparators into a small 72 Ld QFN package. Each channel has independent driver levels, data and high impedance control. Each receiver has dual comparators, which provide high and low threshold levels. • 18V I/O range The ISL55100B uses differential mode digital inputs and can therefore mate directly with LVDS or CML outputs. Single-ended logic families are handled by connecting one of the digital input pins to an appropriate threshold voltage (e.g., 1.4V for TTL compatibility). The comparator outputs are single-ended and the output levels are user defined to mate directly with any digital technology. • Differential or single-ended digital inputs • Low driver output resistance - ROUT typical: 9.0Ω • 50MHz operation • 4 Channel driver/receiver pairs with per pin flexibility • Dual level - per pin - input thresholds • User defined comparator output levels • Low channel-to-channel timing skew • Small footprint (72 Ld QFN) • Pb-free (RoHS compliant) Applications The 18V driver output and receiver input ranges allow this device to interface directly with TTL, ECL, CMOS (3V, 5V and 7V), LVCMOS and custom level circuitry, as well as the high voltage (super voltage) level required for many special test modes for Flash Devices. • Burn in ATE • Wafer level flash memory test • LCD panel test • Low cost ATE • Instrumentation • Emulation • Device programmers Functional Block Diagram QUAD - WIDE RANGE, LOW ROUT, TRI-STATEABLE - DRIVERS VH(0-3) DATA+(0-3) DATA-(0-3) DRVEN+(0-3) DRVEN-(0-3) DOUT(0-3) + - VL(0-3) + - QUAD - DUAL LEVEL COMPARATOR - RECEIVERS COMP HIGH VCC QA(0-3) COMP LOW COMP HIGH CVA(0-3) VEE VCC VINP(0-3) QB(0-3) COMP LOW FN6229 Rev 2.00 December 4, 2014 CVB(0-3) VEE Page 1 of 14 ISL55100B Ordering Information PART NUMBER (Notes 1, 2, 3) PART MARKING ISL55100BIRZ TEMP.

RECEIVER PROPAGATION DELAY MEASUREMENT POINTS FN6229 Rev 2.00 December 4, 2014 Page 7 of 14 ISL55100B Application Information The ISL55100B provides Quad pin drivers and Quad dual level comparator receivers in a small footprint. The four channels may be used as bidirectional or split channels. Drivers have per channel level, data and high impedance controls, while comparators have per channel high and low threshold levels. Receiver Features The receivers are four independent window comparators that feature high output current capability and user defined high and low output levels to interface with a wide variety of logic families. Each receiver comprises two comparators and each comparator has an independent threshold level input, making it easy to implement window comparator functions. The CVA and CVB pins set the threshold levels of the A and B comparators respectively. COMP HIGH and COMP LOW set all the comparator output levels and COMP HIGH must be more positive than COMP LOW. These two inputs are unbuffered supply pins, so the sources driving these pins must provide adequate current for the expected load. COMP HIGH and COMP LOW typically connect to the power supplies of the logic device driven by the comparator outputs. The ‘truth table” for the receivers is given on page 3. Receiver outputs cannot be placed in a HIZ state and do not incorporate any on-chip short circuit current protection. Momentary short circuits to GND or any supply voltage, won’t cause permanent damage, but care must be taken to avoid longer duration short circuits. If tolerable to the application, current limiting resistors can be inserted in series with the QA(0-3) and QB(0-3) outputs to protect the receiver outputs from damage due to overcurrent conditions. Driver Features The drivers are single-ended outputs featuring a wide voltage range, an output stage capable of delivering 125mA while providing a low out resistance and HIZ capability. The driver output can be toggled to drive one of two user defined output levels High (VH) or Low (VL). Driver waveforms are greatly affected by load characteristics. The ISL55100B actually double bonds the VH(0-3) and VL(0-3) supply pins for each channel. The Driver Output Pins (DOUT(0-3)) are triple bonded. Multiple bond wires help reduce the effects of Inductance between the IC Die (Wafer) and the packaging. Also the QFN style of packaging reduces inductance over other types of packaging. While the inductance of a bond wire might seem insignificant, it can reduce high-frequency waveform fidelity. So this should be borne in mind when doing PCB layout and DUT interconnect. Lead lengths should be kept as short as possible, maintaining as much decoupling on the drive rails as possible and make sure scope measurements are made properly. Often the inductance of a scope probe ground can be the actual cause of the waveform distortion. FN6229 Rev 2.00 December 4, 2014 VH and VL (Driver Output Rails) Sets of VH and VL pins are designated for each Driver. These are unbuffered analog inputs that determine the Drive High (VH) and Drive Low (VL) Voltages that the drivers will deliver. These inputs are double bonded to reduce inductance and decrease AC Impedance. Each VH and VL should be decoupled with 4.7µF and 0.1µF capacitors to ground. If all four Driver VH/VLs are bussed, then one 4.7µF can be used. Layouts should also accommodate the placement of capacitance “across” VH and VL. So in addition to decoupling the VH/VL pins to ground, they are also decoupled to each other. Logic Inputs The ISL55100B uses differential mode digital inputs and can therefore mate directly with LVDS or CML outputs. Single- ended logic families are handled by connecting one of the digital input pins to an appropriate threshold voltage (e.g., 1.4V for TTL compatibility). LOWSWING Circuit Option The drivers include switchable circuitry that is optimized for either low (VH-VL < 3V) or high output swings. Configuring the part is accomplished via the LOWSWING pin. Connecting LOWSWING to VEE selects the circuits optimized for low overshoots at low swing operation. Connecting the pin to VCC enables the large signal circuitry (see Figure 7). With LOWSWING = VEE, the low swing circuitry activates whenever VH < VEE + 5V. Set LOWSWING = VEE only if the output swing (VH-VL) is less than 3V and better than 10% overshoots are required. For the best small (low swing) signal performance, the VH/VL common mode voltage [(VH + VL)/2] must be VEE + 1.5V. So if VEE = 0V and the desired swing is 500mV, set VH = 1.75V and VL = 1.25V. Driver and Receiver Overload Protection The ISL55100B is designed to provide minimum and balanced Driver ROUT. Great care should be taken when making use of the ISL55100B low ROUT drivers as there is no internal protection. There is no short circuit protection built into either the driver or the receiver/comparator outputs. Also there are no junction temperature monitors or thermal shutdown features. The driver or receiver outputs may be damaged by more than a momentary short circuit directly to any low impedance voltage. Driver protection can be obtained with a 50Ω series termination resistor that is properly rated. External Logic Supply Option (VEXT) Connection of the VEXT Pin to a 5.5V DC Source (referenced to VEE) will reduce the VCC-VEE current drain. Current drain is directly proportional to Data Rate. This option will help with Power Supply/Dissipation should heat distribution become an issue. Page 8 of 14 ISL55100B Power Supply Bypassing and Printed Circuit Board Layout As with any high frequency device, good printed circuit board layout is necessary for optimum performance. Ground plane construction is highly recommended, lead lengths should be as short as possible and the power supply pins must be well bypassed to reduce the risk of oscillation. For normal single supply operation, where the VEE pin is connected to ground, one 0.1µF ceramic capacitor should be placed from the VCC pin to ground. A 4.7µF tantalum capacitor should then be connected from the VCC pin to ground. This same capacitor combination should be placed at each supply pin to ground if split supplies are to be used. Power Dissipation Considerations Specifying continuous data rates, driver loads and driver level amplitudes are key in determining power supply requirements as well as dissipation/cooling necessities. Driver Output patterns also impact these needs. The faster the pin activity, the greater the need to supply current and remove heat. Figures 17 and 18 address power consumption relative to frequency of operation. These graphs are based on driving 6.0/0.0V out into a 1kΩ load. Theta JA for the device package is 23.0, 16.6 and 14.9°C/W based on Airflows of 0, 1 and 2.5 meters per second. The device is mounted per Note 4 under “Thermal Information” on page 4. With the high speed data rate capability of the ISL55100B, it is possible to exceed the +150°C “absolute maximum junction temperature” as operating conditions and frequencies increase. Therefore, it is important to calculate the maximum junction temperature for the application to determine if operating conditions need to be modified for the device to remain in the safe operating area. The maximum power dissipation allowed in a package is determined according to Equation 1: T JMAX - T AMAX P DMAX = -------------------------------------------- JA (EQ. 1) where: junction temperature over the ambient temperature of the user’s system. Plots indicate temperature change as operating frequency increases (the graph assumes continuous operation). The user should evaluate various heat sink/cooling options in order to control the ambient temperature part of the equation. This is especially true if the users applications require continuous, high speed operation. The reader is cautioned against assuming the same level of thermal performance in actual applications. A careful inspection of conditions in your application should be conducted. Great care must be taken to ensure Die Temperature does not exceed the +150°C Absolute Maximum Thermal Limits. Important Note: The ISL55100B package metal pad (EP) is used for heat sinking of the device. It is electrically connected to the negative supply potential (VEE). If VEE is tied to ground, the thermal pad can be connected to ground. Otherwise, the thermal pad (VEE) must be isolated from other power planes. Power Supply Sequencing The ISL55100B references every supply with respect to VEE. Therefore apply VEE, then VCC followed by the VH, VL busses, then the COMP High and Comp Low followed by the CVA and CVB Supplies. Digital Inputs should be set with a differential bias as soon as possible. In cases where VEXT is being utilized (VEXT = VEE + 5.5V), it should be powered up immediately after VCC. Basically, no pin should be biased above VCC or below VEE. Data Rates Please note that the Frequency (MHz) in Figures 17 and 18 contain two transitions within each period. A digital application that requires a new test pattern every 50ns would be running at a 20MHz Data Rate. Figure 19 reveals 100ns period, in 10MHz frequency parlance, results in two 50ns digital patterns. ESD Protection Figure 6 is the block diagram depicting the ESD protection networks. • TJMAX = Maximum junction temperature • TAMAX = Maximum ambient temperature • JA = Thermal resistance of the package • PDMAX = Maximum power dissipation in the package The maximum power dissipation actually produced by an IC is the total quiescent supply current times the total power supply voltage, plus the power in the IC due to the loads. Power also depends on number of channels changing state, frequency of operation. The extent of continuous active pattern generation/reception will greatly effect dissipation requirements. The power dissipation curves (Figure 17), provide a way to see if the device will overheat. The junction temperature rise above ambient vs operating frequency can be found graphically in Figure 18. This graph is based on the package type Theta JA ratings and actual current/wattage requirements of the ISL55100B when driving a 1k load with a 6V High Level and a 0V Low Rail.
