description
This 1-bit to 4-bit address driver is designed for
1.65-V to 3.6-V V
The SN74AL VCH16344 is used in applications in
which four separate memory locations must be
addressed by a single address.
T o ensure the high-impedance state during power
up or power down, OE
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 characterized for
operation from –40°C to 85°C.

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.
NOTES: 1. The input negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. This value is limited to 4.6 V maximum.
3. The package thermal impedance is calculated in accordance with JESD 51.
