– Industrial:20/25ns(max.)

– Commercial: 20/25ns (max.)

Low power consumption

Battery backup operation – 2V data retention voltage

(L Version only)

Produced with advanced CMOS high-performance

technology

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, CERDIP and SOJ

Military product compliant to MIL-STD-883, Class B
