description/ordering information

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 series damping resistors to reduce

overshoot and undershoot.

The ALVCHS162830A is an improved version of

the LVCHS162830 (non-A version) and has been

optimized for lower power consumption and

higher AC drive. Higher AC drive provides

capability to drive loads with a faster edge rate.

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.
