Overview
CMOS Static RAM 1 Meg (128K x 8-Bit) 71024S Features ◆ 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.
◆ Industrial temperature range (–40°C to +85°C) is available for selected speeds ◆ Green parts available, see ordering information Functional Block Diagram Description The IDT71024 is a 1,048,576-bit high-speed static RAM organized as 128K x 8.
It is fabricated using high-performance, 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 and 32pin 400 mil Plastic SOJ.
