IDT71256SA
Description
The IDT71256SA is a 262,144-bit high-speed Static RAM organized
as 32K x 8. It is fabricated using IDT鈥檚 high-perfomance, high-reliability
CMOS technology. This state-of-the-art technology, combined with
innovative circuit design techniques, provides a cost-effective solution for
high-speed memory needs.
The IDT71256SA has an output enable pin which operates as fast as
6ns, with address access times as fast as 12ns. 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 28-pin 300- and 600-mil Plastic DIP,
28-pin 300 mil Plastic SOJ and TSOP.
