CMOS Static RAM 16K (2K x 8-Bit) IDT6116SA IDT6116LA Features High-speed access and chip select times Military: 2/2/3/4//7/9/12/1 (max.) Industrial: 2/2/3/4 (max.) Commercial: 1/2/2/3/4 (max.) Low-power coumption 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 and plastic 24-pin DIP 24-pin Thin Dip 24-pin SOIC and 24-pin SOJ Military product compliant to MIL-STD-833 Class B Description The IDT6116SA/LA is a 16384-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 1 are available. The circuit also offers a reduced power standby mode. When goes HIGH the circuit will automatically go to and remain in a standby power mode as long as remai 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 coumes 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 6 and 3 mil plastic or ceramic DIP 24-lead gull-wing SOIC and 24-lead J-bend SOJ providing high board-level packing deities. Military grade product is manufactured in compliance to the latest version of MIL-STD-883 Class B making it ideally suited to military temperature applicatio demanding the highest level of performance and reliability.

During this period the I/O pi are in the output state and the input signals must not be applied.. If the LOW traition occurs simultaneously with or after the WE LOW traition the outputs remain in the high-impedance state. 6. Traition is measured ±mv from steady state. 7. OE is continuously HIGH. If OE is LOW during a WE controlled write cycle the write pulse width must be the larger of twp or (twhz + tdw) to allow the I/O drivers to turn off and data to be placed on the bus for the required tdw. If OE is HIGH during a WE controlled write cycle this requirement does not apply and the write pulse is the specified twp. For a controlled write cycle OE may be LOW with no degradation to tcw. 6.42 9
