74AXP2T45GX

2-bit dual supply translating transceiver; 3-state

The 74AXP2T45 is a 2-bit, dual supply transceiver with 3-state outputs that enables bidirectional level translation. It features two 2-bit input-output ports (nA and nB), a direction control input (DIR) and dual supply pins (VCC(A) and VCC(B)). Both VCC(A) and VCC(B) can be supplied at any 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/μs and 5.5 V/s. Pins A and DIR are referenced to VCC(A) and pin B is referenced to VCC(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 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, both A and B are in the high-impedance OFF-state.

Sample

As a Nexperia customer you can order samples via our sales organization.

If you do not have a direct account with Nexperia our network of global and regional distributors is available and equipped to support you with Nexperia samples. Check out the list of official distributors.

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
