Overview
CMOS Static RAM 64K (8K x 8-Bit) 7164S 7164L Features ◆ High-speed address/chip select access time – Commercial: 20/25ns (max.
) – Industrial: 20/25ns (max.
) – Military: 20/25/35/45/55/70/85/100ns (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 ◆ Available in 28-pin DIP, CERDIP and SOJ ◆ Military product compliant to MIL-STD-883, Class B ◆ Industrial temperature range (–40°C to +85°C) is available for selected speeds ◆ Green parts available, see ordering information Description The IDT7164 is a 65,536 bit high-speed static RAM organized as 8K x 8.
It is fabricated using 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 standby 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 CERDIP, a 28-pin 600 mil CERDIP, 300mil Plastic DIP and 300mil SOJ Military grade product is manufactured in compliance with MIL-STD883, Class B, making it ideally suited to military temperature applications demanding the highest level of performance and reliability.
