DESCRIPTION:
The lDT6167 is a 16,384-bit high-speed static RAM organized as 16K x 1. The part is fabricated using IDT’s highperformance, high reliability CMOS technology.
FUNCTIONAL BLOCK DIAGRAM
A0
Access times as fast as 15ns are available. The circuit also
offers a reduced power standby mode. When CS goes HIGH,
the circuit will automatically go to, and remain in, a standby
mode as long as CS remains HIGH. This capability provides
significant system-level power and cooling savings. The lowpower (LA) version also offers a battery backup data retention
capability where the circuit typically consumes only 1µW
operating off a 2V battery.
All inputs and the output of the IDT6167 are TTL-compatible and operate from a single 5V supply, thus simplifying
system designs.
The IDT6167 is packaged in a space-saving 20-pin, 300 mil
Plastic DIP or CERDIP, Plastic 20-pin SOJ, providing high
board-level packing densities.
Military grade product is manufactured in compliance with
the latest revision of MIL-STD-883, Class B, making it ideally
suited to military temperature applications demanding the
highest level of performance and reliability.
