CMOS Static RAM 71016S 1 Meg (64K x 16-Bit) Description Features The IDT71016 is a 1,048,576-bit high-speed Static RAM organized 64K x 16 advanced high-speed CMOS Static RAM as 64K x 16. It is fabricated using high-performance, high-reliability CMOS Equal access and cycle times technology. This state-of-the-art technology, combined with innovative Commercial : 12/15/20ns circuit design techniques, provides a cost-effective solution for high-speed Industrial: 15/20ns memory needs. One Chip Select plus one Output Enable pin The IDT71016 has an output enable pin which operates as fast as 7ns, Bidirectional data inputs and outputs directly TTL- with address access times as fast as 12ns. All bidirectional inputs and compatible outputs of the IDT71016 are TTL-compatible and operation is from a single Low power consumption via chip deselect 5V supply. Fully static asynchronous circuitry is used, requiring no clocks Upper and Lower Byte Enable Pins or refresh for operation. Commercial and industrial product available in 44-pin The IDT71016 is packaged in a JEDEC standard 44-pin Plastic SOJ Plastic SOJ package and 44-pin TSOP package and 44-pin TSOP Type II.
