SN74LV240DWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV240DWR 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 and inverting polarity. The device operates within a supply voltage range of 2.7 V to 3.6 V. Key electrical parameters include a maximum propagation delay of 10 ns at 3.3 V, high-level output current of -12 mA, and low-level output current of 24 mA. It is housed in a 20-pin SOIC package and supports surface-mount installation 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 component meets RoHS compliance standards applicable to your manufacturing region. Ensure the ordering quantity aligns with standard reel sizes to avoid cut-tape handling requirements. Cross-reference the manufacturer's latest datasheet revision to confirm pinout consistency and electrical specifications before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring octal buffering with three-state control in low-voltage environments. It is suitable for applications where 3.3 V logic levels are standard. Consider the propagation delay characteristics relative to system timing requirements. Evaluate the package constraints against available PCB real estate for the 20-SOIC form factor.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LV series of low-voltage CMOS logic devices. It shares functional similarities with other octal buffers like the SN74LVC240 but is optimized for the 2.7 V to 3.6 V supply range. The 'DWR' designation indicates the SOIC-20 package variant supplied in a reel format, distinguishing it from tube-packaged versions.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LV240DW serves as a direct equivalent in tube packaging. SN74LVC240DWR offers similar functionality within a slightly broader voltage range. SN74ABT240DWR provides higher drive currents but requires different voltage levels.
