Description

◆

1M x 4 advanced high-speed CMOS Static RAM

JEDEC Center Power / GND pinout for reduced noise

Equal access and cycle times

The IDT71V428 is a 4,194,304-bit high-speed Static RAM orga-

nized as 1M x 4. It is fabricated using IDT’s high-perfomance, high-

reliability CMOS technology. This state-of-the-art technology, com-

bined with innovative circuit design techniques, provides a cost-

effective solution for high-speed memory needs.

— Commercial and Industrial: 10/12/15ns

Single 3.3V power supply

One Chip Select plus one Output Enable pin

Bidirectional data inputs and outputs directly

LVTTL-compatible

◆

TheIDT71V428has anoutputenablepinwhichoperates as fastas

5ns, withaddress access times as fastas 10ns. Allbidirectionalinputs

andoutputs ofthe IDT71V428are LVTTL-compatible andoperationis

from a single 3.3V supply. Fully static asynchronous circuitry is used,

requiringnoclocks orrefreshforoperation.
