3.3V CMOS静态RAM 4 MEG （ 256K ×16位） 3.3V CMOS STATIC RAM 4 MEG 256K x 16-BIT
DESCRIPTION:
The IDT71V416 is a 4,194,304-bit high-speed Static RAM organized as 256K x 16. 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.
The IDT71V416 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 IDT71V416 are TTL compatible and operation is from a single 3.3V supply. Fully static asynchronous circuitry is used, requiring no clocks or refresh for operation.
The IDT71V416 is packaged in a 44-pin, 400mil Plastic SOJ.
