74AVC2T45

Dual-bit, dual-supply voltage level translator/transceiver; 3-state

The 74AVC2T45 is a dual-bit, dual-supply transceiver that enables bidirectional level translation. It features two data input-output ports (nA and nB), a direction control input (DIR) and dual-supply pins (V_CC(A) and V_CC(B)). Both V_CC(A) and V_CC(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 nA and DIR are referenced to V_CC(A) and pins nB are referenced to V_CC(B). A HIGH on DIR allows transmission from nA to nB and a LOW on DIR allows transmission from nB to nA.

The device is fully specified for partial power-down applications using I_OFF. The I_OFF circuitry disables the output, preventing any damaging backflow current through the device when it is powered down. In Suspend mode when either V_CC(A) or V_CC(B) are at GND level, both A and B are in the high-impedance OFF-state.
