Overview
CMOS Static RAM 256K (32K x 8-Bit) IDT71256SA Features ◆ 32K x 8 advanced high-speed CMOS static RAM ◆ Commercial (0° to 70°C) and Industrial (-40° to 85°C) temperature options ◆ Equal access and cycle times – Commercial: 12ns – Commercial and Industrial: 15/20/25ns ◆ One Chip Select plus one Output Enable pin ◆ Bidirectional data inputs and outputs directly TTL-compatible ◆ Low power consumption via chip deselect ◆ Commercial product available in 28-pin 300-mil Plastic DIP, 300 mil Plastic SOJ and TSOP packages ◆ Industrial product available in 28-pin 300 mil Plastic SOJ and TSOP packages Description The IDT71256SA is a 262,144-bit high-speed Static RAM organized as 32K x 8.
It is fabricated using high-performance, highreliability CMOS technology.
This state-of-the-art technology, combined with innovative circuit design techniques, provides a costeffective solution for high-speed memory needs.
The IDT71256SA 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 IDT71256SA are TTL-compatible and operation is from a single 5V supply.
Fully static asynchronous circuitry is used, requiring no clocks or refresh for operation.
The IDT71256SA is packaged in 28-pin 300-mil Plastic DIP, 28pin 300 mil Plastic SOJ and TSOP.
