SN74HC541DWG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC541DWG4 is an octal buffer and line driver featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an operating temperature range from -40°C to +85°C. The device utilizes a 20-pin Small Outline Integrated Circuit (SOIC) package with a width of 7.5 mm. Key electrical characteristics include a maximum static current of 20 µA at 6 V and output drive capabilities of ±7.8 mA. The logic series is designated as HC, providing CMOS low power consumption while maintaining compatibility with standard TTL input levels.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the suffix G4 indicates lead-free construction and RoHS compliance per Texas Instruments documentation. Confirm the DW package code corresponds to the standard 20-pin SOIC physical dimensions. Ensure the operating temperature grade matches system requirements, as industrial variants may differ. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state capability is required for 2 V to 6 V logic systems. The HC series offers faster switching speeds compared to legacy LS families while maintaining lower power dissipation. Consider the SOIC-20 package constraints regarding board space and thermal management. Verify that the dual enable inputs align with the system's bus control architecture.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Texas Instruments 74HC logic family, which represents high-speed CMOS technology compatible with TTL inputs. The 541 variant specifically provides unidirectional octal buffering. The 'G4' suffix denotes environmental compliance, indicating the absence of halogenated flame retardants and adherence to lead-free manufacturing processes defined by the manufacturer.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct functional equivalents include the SN74HC541DR and SN74HC541DWR, which share identical logical operations and pinouts but may differ in reel packaging quantities. Alternative packages such as TSSOP-20 (SN74HC541PW) require footprint adaptation. Verify that substitute parts maintain the same voltage and temperature specifications.
