CMOS STATIC RAM

64K (16K x 4-BIT)

Integrated Device Technology, Inc.

IDT7188S

IDT7188L

FEATURES:

• High-speed (equal access and cycle times)

— Military: 25/35/45/55/70/85ns (max.)

• Low power consumption

• Battery backup operation — 2V data retention (L version

only)

• Available in high-density industry standard 22-pin, 300

mil ceramic DIP

• Produced with advanced CMOS technology

• Inputs/outputs TTL-compatible

• Military product compliant to MIL-STD-883, Class B

DESCRIPTION:

The IDT7188 is a 65,536-bit high-speed static RAM

organized as 16K x 4. It is fabricated using IDT’s high-

performance, high-reliability technology — CMOS. This state-

of-the-art technology, combined with innovative circuit design

techniques, provides a cost effective approach for memory

intensive applications.

Access times as fast as 25ns are available. The IDT7188

offers a reduced power standby mode, I

SB1

, which is activated

when

goes HIGH. This capability significantly decreases

power while enhancing system reliability. The low-power

version (L) version also offers a battery backup data retention

capability where the circuit typically consumes only 30µW

operating from a 2V battery.

All inputs and outputs are TTL-compatible and operate

from a single 5V supply. The IDT7188 is packaged in 22-pin,

300 mil ceramic DIP providing excellent board-level packing

densities.

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.
