DESCRIPTION:
The IDT71024 is a 1,048,576-bit high-speed static RAM organized as 128K x 8. It is fabricated using IDT’s highperformance, 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 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, 32-pin 400 mil Plastic SOJ, and 32-pin 400 x 820 mil LCC packages.

1.Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
2.VTERM must not exceed VCC + 0.5V.
