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, E may
be driven low to 0V and high to 5.5V. Driving E Rail-to-Rail
minimizes power consumption.
Power-Supply Sequencing
Proper power-supply sequencing is recommended for all CMOS
devices. Always apply V
output or control pins.
