74AHCT240

Octal buffer/line driver; inverting; 3-state

The 74AHCT240 is an 8-bit inverting buffer/line driver with 3-state outputs. This device can be used as two 4-bit buffers or one 8-bit buffer. It features two output enables (1OE and 2OE), each controlling four of the 3-state outputs. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state. Inputs are over voltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments.

Features and benefits

  • Balanced propagation delays

  • All inputs have a Schmitt-trigger action

  • Inputs accepts voltages higher than VCC

  • Operates with TTL input levels

  • 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
