DESCRIPTION/ORDERING INFORMATION
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.
To ensure the high-impedance state during power up
or power down, the output-enable (OE) inputs 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 holds unused or undriven
inputs at a valid logic state. Use of pullup or pulldown
resistors with the bus-hold circuitry is not
recommended.
