description
This 1-bit to 4-bit address driver is designed for
1.65-V to 3.6-V V_CC operation.
The SN74ALVCH162344 is used in applications
in which four separate memory locations must be
addressed by a single address.
The outputs, which are designed to sink up to
12 mA, include equivalent 26-Ω resistors to
reduce overshoot and undershoot.

To ensure the high-impedance state during power
up or power down, the output enable (OE) inputs
should be tied to V_CC through a pullup resistor; the
minimum value of the resistor is determined by the
current-sinking capability of the driver.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
The SN74ALVCH162344 is characterized for operation from –40°C to 85°C.
