description

The SN74ALVCH16344 is a 1-bit to 4-bit address driver used in applications where four separate memory locations must be addressed by a single address.

To ensure the high-impedance state during power up or power down, 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 inputs at a valid logic level.

The SN74ALVCH16344 is available in TI's shrink small-outline (DL) and thin shrink small-outline (DGG) packages, which provide twice the I/O pin count and functionality of standard small-outline packages in the same printed circuit board area.

The SN74ALVCH16344 is characterized for operation from -40°C to 85°C.
