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, ISB1, which is activated when CS 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 a 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.
