This 1-bit to 4-bit address driver is designed for 1.65-V to 3.6-V VCC 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- 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 VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors with the bus-hold circuitry is not recommended.
