74AVC1T45 Dual-supply voltage level translator/transceiver; 3-state Product data sheet
●The 74AVC1T45 is a single bit, dual supply transceiver with 3-state output that enables bidirectional level translation. It features two 1-bit input-output ports (A and B), a direction control input (DIR) and dual supply pins (V-CC(A) and V-CC(B)). Both V-CC(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 and DIR are referenced to V-CC(A)and pin B is referenced to V-cc(B). A HIGH on DIR allows transmission from A to B and a LOW on DIR allows transmission from B to A.
●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.
● Features and benefits:
■Wide supply voltage range:
▲V-CC(A): 0.8 V to 3.6 V

▲320 Mbit/s (< 1.8 V to 3.3 V translation)
▲320 Mbit/s (translate to 2.5 V or 1.8 V)
▲280 Mbit/s (translate to 1.5 V)
▲240 Mbit/s (translate to 1.2 V)

■Inputs accept voltages up to 3.6 V
■Low noise overshoot and undershoot < 10 % of V-cc
■ I-OFF circuitry provides partial Power-down mode operation
■Multiple package options
■Specified from -40 °C to +85 °C and -40 °C to +125 °C
