Description
The IDT71V428 is a 4,194,304-bit high-speed Static RAM orga-
nized as 1M x 4. It is fabricated using IDT’s high-perfomance, high-
reliability CMOS technology. This state-of-the-art technology, com-
bined with innovative circuit design techniques, provides a cost-
effective solution for high-speed memory needs.
The IDT71V428 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 IDT71V428 are LVTTL-compatible and operation is
from a single 3.3V supply. Fully static asynchronous circuitry is used,
requiring no clocks or refresh for operation.
The IDT71V428 is packaged in a 32-pin, 400 mil Plastic SOJ.
