Description
The IDT7164 is a 65,536 bit high-speed static RAM organized as 8K
x 8. It is fabricated using IDT’s high-performance, high-reliability CMOS
technology.
Address access times as fast as 20ns 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.
The IDT7164 is packaged in a 28-pin 300 mil DIP and SOJ and a 28-
pin 600 mil CERDIP.
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.
