The 74AVC1T8128 is a single dual-supply translating 2-input NOR with enable input. It features two data input pins (A, B), one enable input pin (E), one data output pin (Y) and dual-supply pins (VCC(A) and VCC(B)). Both VCC(A) and VCC(B) can be supplied at any voltage between 0.8 V and 3.6 V making the device suitable for translating between any of the low voltage nodes (0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V). Pins A, B and E are referenced to VCC(A) and pin Y is referenced to VCC(B). The logic equation provided at the Y output is: * Y = E + A•B The device is fully specified for partial power-down applications using IOFF. The IOFF circuitry disables the output, 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, the Y output is in the high-impedance OFF-state.
