U74HC240 - OCTAL BUFFERS AND LINE DRIVERS

General Description

The U74HC240 is a octal buffer and line driver with 3-state outputs.

It is organized as two 4-bit buffers/drivers with separate output-enable ( OE ) inputs.

When OE is high, the Y outputs are in a high-impedance state and the outputs neither load nor drive the bus lines.

Key Features

  • S.
  • Wide supply voltage range from 2V to 6V.
  • Max tpd of 9 ns from A to Y at 6V.
  • Low power consumption, ICC = 8 μA (Max. ) at 6V.
  • ±6 mA output driver at 5V.
  • Low Input Current of 1 μA Max.

UNISONIC TECHNOLOGIES CO., LTD U74HC240 OCTAL BUFFERS AND LINE DRIVERS WITH 3-STATE OUTPUTS  DESCRIPTION The U74HC240 is a octal buffer and line driver with 3-state outputs. It is organized as two 4-bit buffers/drivers with separate output-enable ( OE ) inputs. When OE is high, the Y outputs are in a high-impedance state and the outputs neither load nor drive the bus lines. When OE is low, the device passes inverted data from the A inputs to the Y outputs. The U74HC240 is designed to improve the performance and density of 3-state memory address drivers, clock drivers and bus-oriented receivers and transmitters.
