It is fabricated using IDT’s high-perfomance, high-reliability CMOS technology. This state-of-the-art technology, combined with innovativecircuitdesigntechniques,providesacost-effectivesolutionfor high-speed memory needs. The IDT71256SA has an output enable pin which operates as fast as 6ns,withaddress accesstimesasfastas12ns. Allbidirectionalinputsand 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.
