• Manufacturer: Pericom Semiconductor Corporation

Applications Information
Logic Inputs
The logic control inputs can be driven up to +3.6V regardless of the supply voltage. For example, given a +3.3V supply, the output
enables or select pins may be driven low to 0V and high to 3.6V. Driving IN Rail-to-Rail® minimizes power consumption.
Power-Supply Sequencing
Proper power-supply sequencing is advised for all CMOS devices. It is recommended to always apply V
to the input/output or control pins.
