DESCRIPTION:
organized as 256K x 4. 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 high-speed
memory needs.
fast as 6ns, with address access times as fast as 12ns. All
bidirectional inputs and outputs of the IDT71028 are TTL-
compatible and operation is from a single 5V supply. Fully
static asynchronous circuitry is used, requiring no clocks or
refresh for operation.
