SN74LS240DWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LS240DWR is an octal buffer and line driver manufactured by Texas Instruments, belonging to the 74LS logic series. It features eight independent channels with inverting polarity and three-state outputs, housed in a 20-pin SOIC surface-mount package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a functional temperature range from 0°C to 70°C. Electrical characteristics include a maximum high-level output current of -15 mA and a low-level output current of 24 mA.

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 74LS logic family meets the system's power consumption and speed requirements, as this series differs significantly from modern CMOS alternatives in terms of static power draw and propagation delay characteristics.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring standard TTL-compatible logic levels with moderate drive capabilities. Ensure the application environment remains within the specified 0°C to 70°C operating temperature range. Consider the 20-SOIC package dimensions for PCB layout constraints and verify that the 4.75 V to 5.25 V supply voltage aligns with the target circuit design.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the widely used 74-series logic family, specifically the Low-power Schottky (LS) variant known for balanced performance between speed and power dissipation. The SN74LS240DWR shares functional compatibility with other octal buffers like the SN74LS240N, differing primarily in its surface-mount SOIC packaging and reel-based delivery method suitable for high-volume manufacturing.
