74AVC4T3144 Dual-Supply Level Translating Buffer

Nexperia 74AVC4T3144 Dual-Supply Level Translating Buffer is a 4-bit buffer/level translator with 3-state outputs. The 74AVC4T3144 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 Nexperia 74AVC4T3144 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.
