71124

CMOS Static RAM 1 Meg (128K x 8-Bit) Revolutionary Pinout 71124 Features ◆ 128K x 8 advanced high-speed CMOS static RAM ◆ JEDEC revolutionary pinout (center power/GND) for reduced noise. ◆ Equal access and cycle times – Commercial: 12/15/20ns – Industrial: 15/20ns ◆ One Chip Select plus one Output Enable pin ◆ Bidirectional inputs and outputs directly TTL-compatible ◆ Low power consumption via chip deselect ◆ Available in a 32-pin 400 mil Plastic SOJ. Description The IDT71124 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 circuitdesigntechniques,providesa cost-effectivesolutionforhigh-speed memory needs. The JEDEC centerpower/GND pinout reduces noise generation and improves system performance. The IDT71124 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 IDT71124 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 IDT71124 is packaged in a 32-pin 400 mil Plastic SOJ.
