IDT7164L20Y

CMOS静态RAM 64K （ 8K ×8位） CMOS STATIC RAM 64K 8K x 8-BIT

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 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. 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.
