description

This 1-bit to 2-bit address driver is designed for 2.3-V to 3.6-V V_CC operation.

Diodes to V_CC have been added on the inputs to clamp overshoot.

Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.

The outputs, which are designed to sink up to 12 mA, include equivalent 26- resistors to reduce overshoot and undershoot.

To ensure the high-impedance state during power up or power down, the output-enable input 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.

The SN74ALVCHS162830 is characterized for operation from -40°C to 85°C.
