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 inno-

vative 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

5ns, with address access times as fast as 10ns. 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, 400 mil Plastic SOJ and 44-

pin, 400 mil TSOP.
