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.
