Description
The IDT6168 is a 16,384-bit high-speed static RAM organized
as 4K x 4. It is fabricated using lDT鈥檚 high-performance, high-reliability
CMOS technology. This state-of-the-art technology, combined with inno-
vative circuit design techniques, provides a cost-effective approach for
high-speed memory applications.
Access times as fast 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 low-power (LA) version also offers a battery backup data
retention capability where the circuit typically consumes only 1碌W
operating off a 2V battery. All inputs and outputs of the IDT6168 are
TTL-compatible and operate from a single 5V supply.
The IDT6168 is packaged in either a space saving 20-pin, 300-mil
ceramic or plastic DIP or a 20-pin LCC 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.
