1 General description
The 74AVC9112 is a 1-to-4 fan-out buffer suitable for use in clock distribution. It has
a data input (A), four data outputs (Yn) and an output enable input (OE). VCC can be
supplied at any voltage between 0.8 V and 3.6 V. A HIGH on OE causes all outputs to be
pulled LOW via pull-down resistors, a LOW on OE disconnects the pull-down resistors
and enables all outputs.
Schmitt trigger action at all inputs makes the circuit tolerant for slower input rise and fall
time.
The IOFF circuitry disables the output, preventing any damaging backflow current through
the device when it is powered down.
