SN74HC240NSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC240NSR is an octal buffer and line driver manufactured by Texas Instruments, belonging to the HC logic series. It features eight unidirectional channels with three-state outputs controlled by a low-active enable signal. The device operates within a supply voltage range of 2 V to 6 V and supports a load capacitance of 50 pF. It provides high-level output current of -7.8 mA and low-level output current of 7.8 mA. The component functions reliably across an operating temperature range of -40°C to +85°C and is housed in a 20-pin Small Outline Integrated Circuit (SOIC) package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'NSR' against the manufacturer's official documentation to confirm the tape-and-reel packaging configuration and lead-free status. Ensure the ordering part number matches the required SOIC package width and pin count. Cross-reference RoHS compliance certificates with the latest datasheet revisions to guarantee regulatory adherence for your manufacturing process.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring eight-channel buffering with tri-state capability. It is suitable for applications needing operation across a wide voltage range from 2 V to 6 V. Consider its 7.8 mA drive strength for moderate capacitive loads. Verify that the 20-SOIC package dimensions fit your PCB layout constraints and thermal requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74HC240 family of octal buffers and line drivers. It shares functional characteristics with variants such as SN74HC240N and SN74HC240ANSR, differing primarily in packaging style and reel specifications.
