DESCRIPTION:
The IDT71256SA is a 262,144-bit medium-speed Static
RAM organized as 32K x 8. It is fabricated using IDT’s high-
perfomance, high-reliability CMOS technology. This state-of-
the-art technology, combined with innovative circuit design
techniques, provides a cost-effective solution for your memory
needs.
All bidirectional inputs and outputs of the IDT71256SA are
TTL-compatible and operation is from a single 5V supply.
Fully static asynchronous circuitry is used, requiring no clocks
or refresh for operation.
The IDT71256SA is packaged in a 28-pin 300 mil Plastic
SOJ, 28-pin 300 mil Plastic Dip, 28-pin 300 mil TSOP Type I
and 28-pin 600 mil Plastic Dip.
