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, 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 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.
