description
This 1-bit to 4-bit address driver is designed for
1.65-V to 3.6-V V
CC
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.
T o 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 is provided to hold unused or floating data inputs at a valid logic level.
The SN74ALVCH162344 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.
