Applications Information

Logic Inputs

The logic control inputs can be driven up to +5.5V regardless of the supply voltage. For example, given a 5.0V supply, the control or

select pins may be driven low to 0V and high to 5.5V. Driving the control or select pins Rail-toRail R minimizes power consumption.

Power -Supply Sequencing

Proper power-supply sequencing is recommended for all CMOS devices. Always apply VCC before applying

signals to the input/output or control pins.
