Description
512K x 8 advanced high-speed CMOS Static RAM
JEDEC Center Power / GND pinout for reduced noise
Equal access and cycle times
— Commercial and Industrial: 10/12/15ns
Single 3.3V power supply
One Chip Select plus one Output Enable pin
Bidirectional data inputs and outputs directly
TTL-compatible
Low power consumption via chip deselect
Available in 36-pin, 400 mil plastic SOJ package and
44-pin, 400 mil TSOP.
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 innovative circuit design techniques, provides a cost-effective solution for highspeed 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 44pin, 400 mil TSOP.
