74ABT244

Octal buffer/line driver; 3-state

The 74ABT244 is an 8-bit buffer/line driver with 3-state outputs. The device can be used as two 4-bit buffers or one 8-bit buffer. The device 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. This device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.

Features and benefits

  • Supply voltage range from 4.5 to 5.5 V

  • Octal bus interface

  • 3-State buffers

  • BiCMOS high speed and output drive

  • Output capability: +64 mA/–32 mA

  • Direct interface with TTL levels

  • Power-up 3-State

  • Live insertion capability

  • IOFF circuitry provides partial Power-down mode operation

  • Latch-up protection exceeds 500 mA per JESD78 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

  • Specified from -40 °C to +85 °C
