output, which provide high noise immunity and
stable output.
Powerdownprotectionisprovidedoninputand
output and 0 to 7V can be accepted on inputs with
no regard to the supply voltage. It can be
interfaced to 5V signal e nvironment for inputs in
mixed 3.3/5V system.
All inputs and outputs are equipped with
protection circuits against static discharge.
