74AHC541; 74AHCT541

Octal buffer/line driver; 3-state

The 74AHC541; 74AHCT541 is an 8-bit buffer/line driver with 3-state outputs. The device features two output enables (OE1 and OE2). A HIGH on OEn causes the associated outputs to assume a high-impedance OFF-state. Inputs are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments.

Features and benefits

  • Wide supply voltage range from 2.0 to 5.5 V

  • Balanced propagation delays

  • High noise immunity

  • All inputs have a Schmitt-trigger action

  • Overvoltage tolerant inputs to 5.5 V

  • CMOS low power dissipation

  • Input levels:

    • For 74AHC541: CMOS level

    • For 74AHCT541: TTL level

  • Latch-up performance exceeds 100 mA per JESD 78 Class II Level A

  • 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 from -40 °C to +125 °C
