SN54HC240 Datasheet Octal Buffers And Line Drivers

Manufacturer: Texas Instruments

Overview: SN54HC240, SN74HC240 SCLS128G – DECEMBER 1982 – REVISED APRIL 2022 SNx4HC240 Octal Buffers and Line Drivers With 3-State Outputs.

General Description

These octal buffers and line drivers are designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters.

The ’HC240 devices are organized as two 4-bit buffers/drivers with separate output-enable (OE) inputs.

When OE is low, the device passes inverted data from the A inputs to the Y outputs.

Key Features

  • Wide Operating Voltage Range of 2 V to 6 V.
  • High-Current Outputs Drive Up To 15 LSTTL Loads.
  • Low Power Consumption, 80-µA Max ICC.
  • Typical tpd = 9 ns.
  • ±6-mA Output Drive at 5 V.
  • Low Input Current of 1 µA Max.
  • 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers 2.
