74AHCT541ABQ

Octal buffer/line driver; 3-state

The 74AHCT541A is an 8-bit buffer/line driver with 3-state outputs and TTL inputs. The device features two output enables (OE1 and OE2). A HIGH on OEn causes the associated outputs to assume a high-impedance OFF-state.

Designed to operate over a VCC range from 4.5 V to 5.5 V, the inputs are TTL compatible, which allows the device to be used to translate from 3.3 V to 5 V.

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

This device is fully specified for partial Power-down applications using IOFF. The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.

Features and benefits

  • Direct interface with TTL levels

  • Supply voltage range from 4.5 V to 5.5 V

  • Overvoltage tolerant inputs to 5.5 V

  • High noise immunity

  • CMOS low power dissipation

  • Typical tpd of 2.8 ns at 5 V

  • Typical VOL(p) < 0.8 V at VCC = 5 V, Tamb = 25 °C

  • Typical VOH(v) > 2.3 V at VCC = 5 V, Tamb = 25 °C

  • Supports mixed-mode voltage operation on all ports

  • IOFF circuitry provides partial Power-down mode operation

  • Latch-up performance exceeds 250 mA per JESD 78 Class II

  • ESD protection:

    • HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 3000 V

    • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 2000 V

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