High-performance Driver/comparator Active Load On A Single Chip - Analog Devices

The AD53509 is a single chip that performs the pin electronics functions of driver, Comparator and active load in ATE VLSI and memory testers. In addition, a Schottky Diode bridge for the active load and a VCOM Buffer are included internally. The driver is a proprietary design that features three active states: Data High Mode, Data Low Mode and Term Mode as well as an Inhibit State. This facilitates the implementation of high speed active termination. The output voltage range is 2 V to +7 V to accommodate a wide variety of test devices. The output leakage is typically less than 250 nA over the entire sig- nal range. The dual Comparator with an input range equal to the driver output range, features built-in Latches and ECL-compatible outputs. The outputs are capable of driving 50 signal lines terminated to 2 V. Signal tracking capability is upwards of 5 V/ns. The active load CAN be set for up to 40 mA load current with less than a 10 A linearity error through the entire set range. IOH, IOL and the buffered VCOM are independently adjustable. On-board Schottky Diodes provide high speed switching and low capacitance. By Analog Devices, Inc.
