technology.
offers a reduced power standby mode. When CS
goes LOW, the circuit will automatically go to, and remain in, a low-
power stand by mode. The low-power (L) version also offers a battery
backup data retention capability at power supply levels as low as 2V.
operation is from a single 5V supply, simplifying system designs. Fully
static asynchronous circuitry is used, requiring no clocks or refreshing
for operation.
