SN74HCT240PWT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HCT240PWT is an octal buffer and line driver manufactured by Texas Instruments, belonging to the 74HCT logic series. It features two independent four-bit buffers with inverting polarity and three-state outputs, housed in a 20-TSSOP surface-mount package. The device operates within a supply voltage range of 4.5V to 5.5V and supports a wide operating temperature range from -40°C to +85°C. It provides symmetrical output drive currents of 6mA for both high and low states, ensuring robust signal transmission in digital systems requiring level shifting or bus driving capabilities.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number including the suffix 'PWT' to confirm the TSSOP-20 package and tape-and-reel quantity. Confirm RoHS compliance status as per the latest manufacturer documentation. Check for alternate suffixes such as 'G4' which may indicate specific lead-free or environmental certifications. Ensure the source document matches the exact component designation to avoid confusion with non-inverting variants like the SN74HCT244.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when inverting functionality is required for octal data paths. The HCT series ensures compatibility with standard 5V CMOS devices while offering faster switching speeds than legacy LS series. Consider the three-state feature for bidirectional bus applications where output enablement must be controlled. Verify that the 6mA drive current meets the load requirements of the destination circuitry.

Buffers, Drivers, Receivers, Transceivers Part Context

This component is part of the widely used 74HCT family of logic integrated circuits. It serves as a digital buffer designed to isolate stages or drive heavy loads on digital buses. The octal structure allows for parallel processing of eight bits simultaneously. It is distinct from non-inverting counterparts and different packages such as SOIC or DIP versions available within the same logical family.
