SN74HCT240DWR Description

Short technical summary and product information.

The SN74HCT240DWR is an octal buffer and line driver designed by Texas Instruments. This component features 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 electrical specifications include an operating voltage range of 4.5V to 5.5V, with high-current outputs capable of driving up to 15 LSTTL loads. The device exhibits low power consumption, with a maximum ICC of 80µA. Typical propagation delay (tpd) is 12 ns. The inputs are TTL-voltage compatible, and the outputs are 3-state, making them suitable for driving bus lines or buffering memory address registers.

 

This buffer/line driver is designed to improve performance and density in bus-oriented systems. It is packaged in a 20-SOIC (Surface Mount) configuration, with an operating temperature range of -40°C to 85°C. The component is classified under the HCT technology family.

 

Applications for the SN74HCT240DWR include memory address drivers, clock drivers, and bus-oriented receivers and transmitters. Its design facilitates efficient data transfer and signal management in digital systems.
