IDT71V016
Description
The IDT71V016 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 IDT71V016 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 IDT71V016 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 IDT71V016 is packaged in a JEDEC standard 44-pin
Plastic SOJ and 44-pin TSOP Type II.
