Low power consumption
Battery backup operation – 2V data retention voltage
(L Version only)
Produced with advanced CMOS high-performance
technology
Inputs and outputs directly TTL-compatible
Three-state outputs
Addressaccesstimesasfastas20nsareavailableandthecircuitoffers
a reduced power standby mode. When CS1 goes HIGH or CS2 goes
LOW,thecircuitwillautomaticallygoto,andremainin,alow-powerstand-
by mode. The low-power (L) version also offers a battery backup data
retention capability at power supply levels as low as 2V.
All inputs and outputs of the IDT7164 are TTL-compatible and
operation is from a single 5V supply, simplifying system designs. Fully
static asynchronous circuitry is used, requiring no clocks or refreshing
for operation.

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may
cause permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those indicated in the
operational sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect reliability.
2. VTERM must not exceed VCC + 0.5V.

NOTES:
1. A write occurs during the overlap of a LOW WE, a LOW CS1 and a HIGH CS2.
2. tWR1, 2 is measured from the earlier of CS1 or WE going HIGH or CS2 going LOW to the end of the write cycle.
3. During this period, I/O pins are in the output state so that the input signals must not be applied.
4. If the CS1 LOW transition or CS2 HIGH transition occurs simultaneously with or after the WE LOW transition, the outputs remain in a high-impedance state.
5. 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 minimum
write pulse width is as short as the specified tWP.
6. Transition is measured ±200mV from steady state.
