SN74S240DWG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74S240DWG4 is an octal buffer and line driver manufactured by Texas Instruments, belonging to the SN74S logic series. It features eight independent channels with inverting polarity and three-state outputs, housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -40 °C to +85 °C. Key electrical parameters include a maximum high-level output current of -24 mA and a maximum low-level output current of 24 mA. Propagation delay is specified at 6 ns under standard test conditions.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the package type matches the required PCB footprint. Ensure the operating temperature range meets system environmental constraints. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed buffering with significant drive capability is required. The SN74S series offers faster propagation delays compared to standard LS or HC families. Consider the three-state output functionality for shared bus applications. Verify that the 5V supply voltage aligns with the system power rails.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74S (Schottky) logic family, known for high speed. It is functionally similar to other octal buffers like the SN74LS240 but with improved switching speeds. The 'G4' suffix typically denotes environmental compliance modifications. It serves as a critical interface component between microprocessors and peripheral devices.
