This 1-bit to 4-bit address driver is designed for
1.65-V to 3.6-V VCC operation.
The SN74ALVCH16344 is used in applications in
which four separate memory locations must be
addressed by a single address.

To ensure the high-impedance state during power up
or power down, OE 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.
