1. General description

The 74AVC4T3144-Q100 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 VCC(A) to VCC(B) and one input

from VCC(B) to VCC(A). OE, An and YA4 are referenced to VCC(A) and YBn and B4 are referenced to

VCC(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 IOFF. The IOFF circuitry

disables outputs, preventing any damaging backflow current through the device when it is powered

down. In suspend mode when either VCC(A) or VCC(B) are at GND level, all outputs are in the highimpedance

OFF-state.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.
