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.
