74VHC244; 74VHCT244

Octal buffer/line driver; 3-state

The 74VHC244; 74VHCT244 are a high-speed Si-gate CMOS devices.

The 74VHC244; 74VHCT244 have 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.

特性

  • Balanced propagation delays

  • All inputs have a Schmitt-trigger action

  • Inputs accepts voltages higher than VCC

  • Input levels:

    • The 74VHC244 operates with CMOS input level

    • The 74VHCT244 operates with TTL input level

  • 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
