DESCRIPTION:

The IDT71V424 is a 4,194,304-bit high-speed Static RAM

organized as 512K x 8. 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 IDT71V424 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 IDT71V424 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 IDT71V424 is packaged in a 36-pin, 400mil Plastic

SOJ.
