CMOS STATIC RAM

64K (8K x 8-BIT)

Integrated Device Technology, Inc.

FEATURES:

DESCRIPTION:

• High-speed address/chip select access time

— Military: 20/25/30/35/45/55/70/85ns (max.)

— Commercial: 15/20/25/35/70ns (max.)

• Low power consumption

• Battery backup operation — 2V data retention voltage

(L Version only)

• Produced with advanced CMOS high-performance

technology

• Inputs and outputs directly TTL-compatible

• Three-state outputs

The IDT7164 is a 65,536 bit high-speed static RAM orga-

nized as 8K x 8. It is fabricated using IDT’s high-performance,

high-reliability CMOS technology.

Address access times as fast as 15ns are available and the

circuit offers a reduced power standby mode. When CS1 goes

HIGH or CS2 goes LOW, the circuit will automatically go to,

and remain in, a low-power stand by mode. The low-power (L)

version also offers a battery backup data retention capability

at power supply levels as low as 2V.

All inputs and outputs of the IDT7164 are TTL-compatible

and operation is from a single 5V supply, simplifying system

designs. Fully static asynchronous circuitry is used, requiring

no clocks or refreshing for operation.

• Available in:

— 28-pin DIP and SOJ

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

The IDT7164 is packaged in a 28-pin 300 mil DIP and SOJ;

and 28-pin 600 mil DIP.

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.
