74AVC4T3144GU12X

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 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 lOFF. 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.
