DESCRIPTION

This 1-bit to 2-bit address driver is designed for 2.3-V

to 3.6-V VCC operation.

Diodes to VCC have been added on the inputs to

clamp overshoot.

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.

The outputs, which are designed to sink up to 12 mA,

include equivalent 26-W series resistors to reduce

overshoot and undershoot.

To ensure the high-impedance state during power up

or power down, the output-enable (OE) input 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.
