1. General description
The 74AVC1T1004 is a translating 1-to-4 fan-out buffer suitable for use in clock distribution. It has
dual supplies (VCC(A) and VCC(B)) for voltage translation. It also has a data input (A), four data
outputs (Yn) and an output enable input (OE). VCC(A) and VCC(B) can be independently supplied
at any voltage between 0.8 V and 3.6 V. It makes the device suitable for low voltage translation
between any of the following voltages: 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V. The levels of A
and OE are referenced to VCC(A), outputs Yn are referenced to VCC(B). This supply configuration
ensures that the fanned out signals can be used in level shifting. 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.
