Overview
High Performance Driver/Comparator, Active Load on a Single Chip AD53509 FEATURES 250 MHz operation Driver/comparator and active load included On-chip Schottky diode bridge 52-lead LQFP_EP package APPLICATIONS Automatic test equipment (ATE) Semiconductor test systems Board test systems Instrumentation and characterization equipment GENERAL DESCRIPTION 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.
The output voltage range is −2 V to +7 V to accommodate a wide variety of test devices.
The output leakage is typically <250 nA over the signal range.
The dual comparator, with an input range equal to the driver output range, features built-in latches and...
