74AVC4T3144
4-bit dual-supply buffer/level translator; 3-state
Rev. 2 — 24 July 2018 Product data sheet
1. General description
The 74AVC4T3144 is a 4-bit, dual-supply level translating buffer with 3-state outputs. It features
four data inputs (An and B4), four data outputs (YBn and YA4), and an output enable input (OE).
The device is configured to translate three inputs from V
CC(A)
to V
CC(B)
and one input from V
CC(B)
to V
CC(A)
. OE, An and YA4 are referenced to V
CC(A)
and YBn and B4 are referenced to V
CC(B)
. A
HIGH on OE causes the outputs to assume a high-impedance OFF-state.
The device is fully specified for partial power-down applications using I
OFF
. The I
OFF
circuitry
disables outputs, preventing any damaging backflow current through the device when it is powered
down. In suspend mode when either V
CC(A)
or V
CC(B)
are at GND level, all outputs are in the high-
impedance OFF-state.
