74AHC(T)244-Q100

Octal buffer/line driver; 3-state

The 74AHC244-Q100; 74AHCT244-Q100 is a high-speed Si-gate CMOS device.

The 74AHC244-Q100; 74AHCT244-Q100 has octal non-inverting buffer/line drivers with 3-state outputs. The 3-state outputs are controlled by the output enable inputs (nOE). A HIGH on nOE causes the outputs to assume a high-impedance OFF-state.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.

Features

  • Automotive product qualification in accordance with AEC-Q100 (Grade 1)
    • Specified from -40 °C to +85 °C and from -40 °C to +125 °C
  • Balanced propagation delays
  • All inputs have a Schmitt trigger action
  • Inputs accept voltages higher than VCC
  • For 74AHC244-Q100 only: operates with CMOS input levels
  • For 74AHCT244-Q100 only: operates with TTL input levels
  • ESD protection:
    • MIL-STD-883, method 3015 exceeds 2000 V
    • HBM JESD22-A114F exceeds 2000 V
    • MM JESD22-A115-A exceeds 200 V (C = 200 pf, R = 0 Ω)
  • Multiple package options
