74AXP1T34GX

Dual supply translating buffer

The 74AXP1T34 is a dual supply translating buffer. It features one input (A), an output (Y) and dual supply pins (VCCI and VCCO). The inputs are referenced to VCCI and the output is referenced to VCCO. All inputs can be connected directly to VCCI or GND. VCCI can be supplied at any voltage between 0.7 V and 2.75 V and VCCO can be supplied at any voltage between 1.2 V and 5.5 V. This feature allows voltage level translation.

Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.

This device ensures very low static and dynamic power consumption across the entire supply range and is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.

Not recommended for new designs (NRND).

Features and benefits

  • Wide supply voltage range:

    • VCCI: 0.7 V to 2.75 V

    • VCCO: 1.2 V to 5.5 V

  • Low input capacitance; CI = 0.6 pF (typical)

  • Low output capacitance; CO = 1.8 pF (typical)

  • Low dynamic power consumption; CPD = 0.4 pF at VCCI = 1.2 V (typical)

  • Low dynamic power consumption; CPD = 7.1 pF at VCCO = 3.3 V (typical)

  • Low static power consumption; ICCI = 0.5 μA (85 °C maximum)

  • Low static power consumption; ICCO = 1.8 μA (85 °C maximum)

  • High noise immunity

  • Complies with JEDEC standard:

    • JESD8-12A.01 (1.1 V to 1.3 V; A input)

    • JESD8-11A.01 (1.4 V to 1.6 V)

    • JESD8-7A (1.65 V to 1.95 V)

    • JESD8-5A.01 (2.3 V to 2.7 V)

    • JESD8-C (2.7 V to 3.6 V; Y output)

    • JESD12-6 (4.5 V to 5.5 V; Y output)

  • ESD protection:

    • HBM ANSI/ESDA/JEDEC JS-001 Class 2 exceeds 2000 V

    • CDM JESD22-C101E exceeds 1000 V

  • Latch-up performance exceeds 100 mA per JESD78D Class II

  • Inputs accept voltages up to 2.75 V

  • Low noise overshoot and undershoot < 10% of VCCO

  • IOFF circuitry provides partial power-down mode operation

  • Multiple package options

  • Specified from -40 °C to +85 °C

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.
