74AXP4T245PW

4-bit dual supply translating transceiver; 3-state

The 74AXP4T245 is an 4-bit dual supply translating transceiver with 3-state outputs that enable bidirectional level translation. The device can be used as two 2-bit transceivers or as a 4-bit transceiver. It features four 2-bit input-output ports (nAn and nBn), a direction control input (nDIR), a output enable input (nOE) 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 nAn, nOE and nDIR are referenced to VCC(A) and pins nBn are referenced to VCC(B). A HIGH on nDIR allows transmission from nAn to nBn and a LOW on nDIR allows transmission from nBn to nAn. The output enable input (nOE) can be used to disable the outputs so the buses are effectively isolated.

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 nAn and nBn are in the high-impedance OFF-state.

Features and benefits

  • Wide supply voltage range for VCC(A) and VCC(B): 0.9 V to 5.5 V

  • Low input capacitance; CI = 1.2 pF (typical)

  • Low output capacitance; CO = 3.6 pF (typical)

  • Low dynamic power consumption; CPD = 10 pF (typical)

  • Low static power consumption; ICC = 2 μA (25 °C maximum)

  • High noise immunity

  • Complies with JEDEC standard:

    • JESD8-12 (1.1 V to 1.3 V; inputs)

    • JESD8-11 (1.4 V to 1.6 V)

    • JESD8-7 (1.65 V to 1.95 V)

    • JESD8-5 (2.3 V to 2.7 V)

    • JESD8C (2.7 V to 3.6 V)

    • JESD12-6 (4.5 V to 5.5 V)

  • ESD protection:

    • HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2 kV

    • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1 kV

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

  • Inputs accept voltages up to 5.5 V

  • Typical data rate figures:

    • 320 Mbps when translating from 1.8 V to 3.3 V (up translation)

    • 175 Mbps when translating from 3.3 V to 1.8 V (down translation)

  • Low noise overshoot and undershoot < 10% of VCCO

  • IOFF circuitry provides partial power-down mode operation

  • Specified from -40 °C to +125 °C

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.
