Description
The IDT71V424 is a 4,194,304-bit high-speed Static RAM organized
as 512K x 8. It is fabricated using high-performance, 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
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.
