1. General description
The 74AHCT07A is a hex buffer with open-drain outputs. The output s ar e ope n- drain a nd
can be connected to other open-drain outputs to implement active-LOW wired-OR or
active-HIGH wired-AND functions.
Designed to operate over a V
CC
range from 4.5 V to 5.5 V, the input s are TTL comp atib le,
which allows the device to be used to translate from 3.3 V to 5 V.
Schmitt-trigger action at all input s makes the circuit tolerant of slower input rise and fall
times.
This device is fully specified for partial Power-down applications using I
OFF
.
The I
OFF
circuitry disables the ou tp u t, pr eve n tin g the damaging backflow current through
the device when it is powered down.
