Information

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 ’HCT240 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. When OE is high, the outputs are in the high-impedance state.

Key Features

  • Operating Voltage Range of 4.5 V to 5.5 V
  • High-Current Outputs Drive Up To 15
  • LSTTL Loads
  • Low Power Consumption, 80-µA Max ICC
  • Typical tpd = 12 ns
  • ±6-mA Output Drive at 5 V
  • Low Input Current of 1 µA Max
  • Inputs Are TTL-Voltage Compatible
  • 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers
  • Technical Attributes
