DESCRIPTION/ORDERING INFORMATION
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-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 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.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
The input negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.
This value is limited to 4.6 V maximum.
The package thermal impedance is calculated in accordance with JESD 51-7.
