    74AVCH2T45GN

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

    The 74AVCH2T45 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 (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 nA and DIR are referenced to VCC(A) and pins nB are referenced to VCC(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 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.

    The 74AVCH2T45 has active bus hold circuitry which is provided to hold unused or floating data inputs at a valid logic level. This feature eliminates the need for external pull-up or pull-down resistors.

    Features and benefits

    • Wide supply voltage range: 0.8 V to 3.6 V for VCC(A) and VCC(B)

    • High noise immunity

    • Suspend mode

    • Bus hold on data inputs

    • Inputs accept voltages up to 3.6 V

    • Low noise overshoot and undershoot < 10 % of VCC

    • IOFF circuitry provides partial Power-down mode operation

    • Maximum data rates:

      • 500 Mbps (1.8 V to 3.3 V translation)

      • 320 Mbps (< 1.8 V to 3.3 V translation)

    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.
