Features, Applications


High-speed (equal access and cycle time) Military: 25/35/45/55/70/85/100ns (max.) Commercial: 15/20/25ns (max.) Low power consumption Battery backup operation 2V data retention voltage (IDT6167LA only) Available in 20-pin CERDIP and Plastic DIP, and 20-pin SOJ Produced with advanced CMOS high-performance technology CMOS process virtually eliminates alpha particle soft-error rates Separate data input and output Military product compliant to MIL-STD-883, Class B 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 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 1W 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 and a Plastic 20-pin 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.
