SN74LV240ADWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV240ADWR is an octal buffer and line driver manufactured by Texas Instruments, belonging to the LV (Low-Voltage CMOS) logic family. It features eight independent channels with three-state outputs housed in a 20-pin SOIC package. The device operates within a supply voltage range of 2.7 V to 3.6 V. It supports both inverting and non-inverting configurations via external control inputs. Key electrical characteristics include a propagation delay of 5.8 ns at 3.3 V, high-level output current of -12 mA, and low-level output current of 24 mA. The component is designed for surface-mount installation and functions reliably across an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DWR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the RoHS compliance status aligns with current environmental regulations for your manufacturing region. Ensure the ordering quantity matches the reel specifications provided by the manufacturer or authorized distributors to avoid handling discrepancies.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring octal buffering with three-state outputs at 3.3 V logic levels. It is suitable for applications demanding moderate drive strength and propagation delays around 5.8 ns. Consider alternative families like LVC or ABT if lower static power consumption or higher drive currents are necessary for the specific system requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments SN74LV series, which bridges the performance gap between standard 5 V logic and lower voltage CMOS technologies. The SN74LV240A variant specifically offers improved switching speeds compared to older LS or ALS equivalents while maintaining pinout compatibility with legacy designs. It serves as a critical interface component in mixed-voltage digital systems.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LV240ADW is the tube-packaged equivalent of the same functional device. SN74LVT240ADWR shares identical functionality but operates within a slightly different voltage window defined by the LVT specification. Verify pin compatibility before substituting with other octal buffer variants from different manufacturers.
