Military product compliant to MIL-STD-833, Class B
Description
The IDT6116SA/LA is a 16,384-bit high-speed static RAM
organized as 2K x 8. It is fabricated using IDT's high-performance,
high-reliability CMOS technology.
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 power 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 1µW to 4µW operating off a 2V battery.
All inputs and outputs of the IDT6116SA/LA are TTL-compatible. Fully
static asynchronous circuitry is used, requiring no clocks or refreshing
for operation.
The IDT6116SA/LA is packaged in 24-pin 600 and 300 mil plastic or
ceramic DIP, 24-lead gull-wing SOIC, and 24-lead J-bend SOJ providing
high board-level packing densities.
Military grade product is manufactured in compliance to the latest
version of MIL-STD-883, Class B, making it ideally suited to military
temperature applications demanding the highest level of performance and
reliability.
