High-speed access and chip select times
– Military: 20/25/35/45/55/70/90/120/150ns (max.)
– Industrial: 20/25ns (max.)
– Commercial: 15/20/25ns (max.)
Low-power consumption
Battery backup operation
– 2V data retention voltage (LA version only)
Produced with advanced CMOS high-performance
technology
CMOS process virtually eliminates alpha particle soft-error
rates
Input and output directly TTL-compatible
Static operation: no clocks or refresh required
Available in ceramic 24-pin DIP, ceramic and plastic 24-pin Thin
Dip and 24-pin SOIC
Military product compliant to MIL-STD-833, Class B
The IDT6116SA/LA is a 16,384-bit high-speed static RAM organized
as 2K x 8. It is fabricated using 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 300mil plastic DIP, 24-pin
600mil and 300mil ceramic DIP, or 24-lead gull-wing SOIC providing high
board-level packing densities.
Military grade product is manufactured in compliance to MIL-STD-883,
Class B, making it ideally suited to military temperature applications
demanding the highest level of performance and reliability.
