CMOS STATIC RAM

1 MEG (256K x 4-BIT)

IDT71028

Integrated Device Technology, Inc.

FEATURES:

• 256K x 4 advanced high-speed CMOS static RAM

• Equal access and cycle times

— Military: 15/17/20/25ns

— Commercial: 12/15/17ns

• One Chip Select plus one Output Enable pin

• Bidirectional data Inputs and outputs directly

TTL-compatible

• Low power consumption via chip deselect

• Available in 28-pin Ceramic DIP, Plastic DIP, 300 mil and

400 mil Plastic SOJ, and LCC packages

• Military product compliant to MIL-STD-883, Class B

DESCRIPTION:

The IDT71028 is a 1,024,576-bit high-speed static RAM

organized as 256K x 4. It is fabricated using IDT’s high-

perfomance, 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 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 TTL-

compatible 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 Ceramic DIP,

28-pin 400 mil Plastic DIP, 28-pin 300 mil Plastic SOJ, 28-pin

400 mil Plastic SOJ, and 28-pin Leadless Chip Carrier pack-

ages.
