IDT6167SA
IDT6167LA
CMOS STATIC RAM
16K (16K x 1-BIT)
Integrated Device Technology, Inc.
Access times as fast as 15ns are available. The circuit also
offers a reduced power standby mode. When CSgoes 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 1µW
operating off a 2V battery.
FEATURES:
• High-speed (equal access and cycle time)
— Military: 15/20/25/35/45/55/70/85/100ns (max.)
— Commercial: 15/20/25/35ns (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
All inputs and the output of the IDT6167 are TTL-compat-
ible and operate from a single 5V supply, thus simplifying
system designs.
TheIDT6167ispackagedinaspace-saving20-pin, 300mil
Plastic DIP or CERDIP, Plastic 20-pin SOJ, 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.
• CMOS process virtually eliminates alpha particle soft-
error rates
• Separate data input and output
• Military product compliant to MIL-STD-883, Class B
DESCRIPTION:
The lDT6167 is a 16,384-bit high-speed static RAM orga-
nized as 16K x 1. The part is fabricated using IDT’s high-
performance, high reliability CMOS technology.

NOTES:
1. WE or CS must be inactive during all address transitions.
2. A write occurs during the overlap of a LOW CS and a LOW WE.
3. tWR is measured from the earlier of CS or WE going HIGH to the end of the write cycle.
4. If the CS low transition occurs simultaneously with or after the WE LOW transition, the outputs remain in the high-impedance state.
5. Transition is measured ±200mV from steady state.
6. During this period, the I/O pins are in the output state and the input signals must not be applied.
