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.
The IDT71028 is a 1,048,576-bit high-speed static RAM organized as 256K x 4. It is fabricated using IDT's highperfomance, high-reliability CMOS technology. This state-ofthe-art technology, combined with innovative circuit design techniques, provides a cost-effective solution for high-speed memory needs.
The IDT71028 has an output enable pin which operates as fast as 6ns, with address access times as fast as 12ns. All bidirectional inputs and outputs of the IDT71028 are TTLcompatible and operation is from a single 5V supply. Fully static asynchronous circuitry is used, requiring no clocks or refresh for operation.
The IDT71028 is packaged in 28-pin 400 mil Plastic SOJ package.
