DESCRIPTION:
The IDT71V416 is a 4,194,304-bit high-speed Static RAM
organized as 256K x 16. 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 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.
