General description

The 74HC240; 74HCT240 is a high-speed Si-gate CMOS device and is pin compatible with Low-Power Schottky TTL (LSTTL).

The 74HC240; 74HCT240 is a dual octal inverting buffer/line driver with 3-state outputs. The 3-state outputs are controlled by the output enable inputs 1OE and 2OE. A HIGH on nOE causes the outputs to assume a high impedance OFF-state.

The 74HC240; 74HCT240 is similar to the 74HC244; 74HCT244 but has inverting outputs.

Features

  • Inverting 3-state outputs
  • Multiple package options
  • Complies with JEDEC standard no. 7 A
  • ESD protection:
    • HBM JESD22-A114-D exceeds 2000 V
    • MM JESD22-A115-A exceeds 200 V
  • Specified from -40 Cel to +85 Cel and from -40 Cel to +125 Cel
