Product Information

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

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