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.



Description

The IDT7198L is a 65,536 bit high-speed static RAM orga nized 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 inten-
sive applications.

Access times as fast as 20ns are available. The IDT7198L offers a reduced power standby mode, ISB1, which is activated when  CS1  or  CS2 goes HIGH. This capability decreases power, while enhancing system reliability. The low-power version (L) also offers a battery backup data retention capability 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 IDT7198L 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.
