4K x 36 BiCMOS SYNCHRONOUS DUAL-PORT STATIC RAM MODULE
MILITARY AND COMMERCIAL TEMPERATURE RANGES
PGA (Pin Grid Array).
All IDT military modules are constructed with semiconduc-
tor components manufactured in compliance with the latest
revision of MIL-STD-883, Class B making them ideally suited
to applications demanding the highest level of performance
and reliability.

1. Stresses greater than those listed under ABSOLUTE MAXIMUM RAT-
INGS may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions
above those indicated in the operational sections of this specification is not
implied. Exposure to absolute maximum rating conditions for extended
periods may affect reliability.
2. Inputs and Vcc terminals only.
NOTE:
