CMOS STATIC RAMs

64K (16K x 4-BIT)

Added Chip Select and Output Controls

IDT7198S

IDT7198L

Integrated Device Technology, Inc.

FEATURES:

• Fast Output Enable (

) pin available for added system

flexibility

• Multiple Chip Selects (

) simplify system design

and operation

• High speed (equal access and cycle times)

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

• Low power consumption

• Battery back-up operation—2V data retention (L version

only)

• 24-pin CERDIP, high-density 28-pin leadless chip carrier,

and 24-pin CERPACK packaging available

• Produced with advanced CMOS technology

• Bidirectional data inputs and outputs

• Inputs/outputs TTL-compatible

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

DESCRIPTION:

The IDT7198 is a 65,536 bit high-speed static RAM orga-

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

mance, high-reliability technology—CMOS. This state-of-the-

art technology, combined with innovative circuit design tech-

niques, provides a cost effective approach for memory inten-

sive applications.

Access times as fast as 20ns are available. The IDT7198

offers a reduced power standby mode, I

SB1

, which is activated

when

goes HIGH. This capability decreases

power, while enhancing system reliability. The low-power

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

bility where the circuit typically consumes only 30µW when

operating from a 2V battery.

All inputs and outputs are TTL-compatible and operate

from a single 5V supply.

The lDT7198 is packaged in either a 24-pin ceramic DlP,

28-pin leadless chip carrier, and 24-pin CERPACK.

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.
