IDT71681SA/LA, IDT71682SA/LA
CMOS STATIC RAMS 16K (4K x 4-BIT) Separate Data Inputs and Outputs
MILITARY AND COMMERCIAL TEMPERATURE RANGES
DESCRIPTION (Continued):
The IDT71681/IDT71682 are packaged in either space-
saving 24-pin, 300-mil DlPs, CERPACKS, or 28-pin leadless
chip carriers.
Military grade product is manufactured in compliance with
the latest revision of MIL-STD-883, Class B, making it ideally
suited to military temperature applications demanding the
highest level of performance and reliability.

1. Stresses greater than those listed under ABSOLUTE MAXIMUM
RATINGS 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.
