Description
The IDT71016 is a 1,048,576-bit high-speed Static RAM organized
as 64K x 16. 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 IDT71016 has an output enable pin which operates as fast as 7ns,
with address access times as fast as 12ns. All bidirectional inputs and
outputs of the IDT71016 are TTL-compatible and operation is from a single
5V supply. Fully static asynchronous circuitry is used, requiring no clocks
or refresh for operation.
The IDT71016 is packaged in a JEDEC standard 44-pin Plastic SOJ
and 44-pin TSOP Type II.
