General description
The 74AVC1T1022 is a translating 1-to-4 fan-out buffer suitable for use in clock
distribution. It has dual supplies (V
CC(A)
and V
CC(B)
) for voltage translation. It also has a
data input (A), four data outputs (1Yn and 2Yn) and an output enable input (OE). V
CC(A)
and V
CC(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, OE and 1Yn are
referenced to V
CC(A)
, outputs 2Yn are referenced to V
CC(B)
. This supply configuration
ensures that two of 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 I
OFF
circuitry disables the output, preventing any damaging backflow current through
the device when it is powered down.
