74LVC4245AD

Octal dual supply translating transceiver; 3-state

The 74LVC4245A is an octal dual supply translating transceiver featuring 3-state bus compatible outputs in both send and receive directions. It is designed to interface between a 3 V and 5 V bus in a mixed 3 V and 5 V supply environment. The device features an output enable input (OE) and a send/receive input (DIR) for direction control. A HIGH on OE causes the outputs to assume a high-impedance OFF-state, effectively isolating the buses. In suspend mode, when either supply is zero, there is no current path between supplies. VCCA ≥ VCCB, except in suspend mode. Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.

Features and benefits

  • 5 V tolerant inputs/outputs, for interfacing with 5 V logic

  • Wide supply voltage range:

    • 3 V bus (VCC(B)): 1.5 V to 3.6 V

    • 5 V bus (VCC(A)): 1.5 V to 5.5 V

  • CMOS low-power consumption

  • TTL interface capability at 3.3 V

  • Overvoltage tolerant control inputs to 5.5 V

  • High-impedance when VCC(A) = 0 V

  • Complies with JEDEC standard no. JESD8B/JESD36

  • Latch-up performance meets requirements of JESD78 Class 1

  • ESD protection:

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

    • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V

  • Multiple package options

  • Specified from -40 °C to +85 °C and -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.
