1 General description

The 74LVC4T3144-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 high-impedance 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.
