74AXP1T45 1-bit dual supply translating transceiver 3-state Rev. 1 25 June 2020 Product data sheet 1. General description The 74AXP1T45 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 and V ). Both V and V can be supplied at any CC(A) CC(B) CC(A) CC(B) voltage between 0.9 V and 5.5 V making the device suitable for translating between any of the low voltage nodes (0.9 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V and 5.0 V). No power supply sequencing is required and output glitches during power supply transitions are prevented using patented circuitry. As a result glitches will not appear on the outputs for supply transitions during power-up/down between 20 mV/s and 5.5 V/s. Pins A and DIR are referenced to V and pin B is referenced CC(A) to V . A HIGH on DIR allows transmission from A to B and a LOW on DIR allows transmission CC(B) from B to A. The device is fully specified for partial power-down applications using I . The I circuitry OFF OFF disables the output, preventing any damaging backflow current through the device when it is powered down. In suspend mode when either V or V are at GND level, both A and B are CC(A) CC(B) in the high-impedance OFF-state. 2.
