ApplicationInformation

Logic Inputs

The logic control inpus can be driven up to +3.6V regardless of the

supply voltage. For example, given a +3.3V supply, IN may be driven

LOW to 0V and HIGH to 3.6V. Driving IN Rail-toRail minimizes

power consumption.

Power-Supply Sequencing and Hot Plug Information

Proper power-supply sequencing is advised for all CMOS devices.

signals to the input/output or control pins.
