General description

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

The 74AHC244; 74AHCT244 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.

Features

  • Balanced propagation delays
  • All inputs have a Schmitt-trigger action
  • Inputs accepts voltages higher than VCC
  • For 74AHC244 only: operates with CMOS input levels
  • For 74AHCT244 only: operates with TTL input levels
  • ESD protection:
    • HBM JESD22-A114E exceeds 2000 V
    • MM JESD22-A115-A exceeds 200 V
    • CDM JESD22-C101C exceeds 1000 V
  • Multiple package options
  • Specified from -40 Cel to +85 Cel and from -40 Cel to +125 Cel
