IDT71024S/MS
Description
128K x 8 advanced high-speed CMOS static RAM
Commercial (0°C to +70°C), Industrial (–40°C to +85°C)
Equal access and cycle times
— Commercial and Industrial: 12/15/20ns
Two Chip Selects plus one Output Enable pin
Bidirectional inputs and outputs directly
TTL-compatible
Low power consumption via chip deselect
Available in 300 and 400 mil Plastic SOJ.
The IDT71024 is a 1,048,576-bit high-speed static RAM organized as
128K x 8. It is fabricated using IDT’s high-performance, 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 IDT71024 has an output enable pin which operates as fast
as 6ns, with address access times as fast as 12ns available. All
bidirectional inputs and outputs of the IDT71024 are TTL-compatible, and operation is from a single 5V supply. Fully static asynchronous circuitry is used; no clocks or refreshes are required for
operation.
The IDT71024 is packaged in 32-pin 300 mil Plastic SOJ and 32pin 400 mil Plastic SOJ.
