SN74LVC541ARGYRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC541ARGYRG4 is an octal buffer and line driver from the Texas Instruments LVC logic family, housed in a 20-VQFN package. It features non-inverting polarity with three-state outputs. The device operates within a supply voltage range of 1.65 V to 3.6 V. Key electrical parameters include a high-level output current of -24 mA and a low-level output current of 24 mA. Static current is specified at 10 uA. Propagation delay is 5.6 ns at 2.7 V and 5.1 ns at 3.3 V. The component supports an operating temperature range from -40°C to +125°C.

• Clock buffering and distribution networks
• Memory interface drivers
• Mobile and handheld equipment with low voltage constraints

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and green material status as per manufacturer standards. Confirm the VQFN-20 package dimensions match your PCB footprint requirements precisely. Ensure the design accounts for the thermal dissipation characteristics inherent to the exposed pad VQFN configuration during operation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state control is required for low-voltage applications. The LVC series offers faster switching speeds compared to standard LV devices while maintaining compatibility with 3.3V and 2.5V logic levels. Consider the VQFN package for space-constrained designs requiring efficient thermal management through the bottom pad.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC541A family of octal buffers. Variants exist in different packages such as SOIC, TSSOP, and PWREP. The ARGYR designation specifically identifies the VQFN package variant. The G4 suffix typically denotes environmental compliance attributes defined by Texas Instruments for lead-free and halogen-free manufacturing processes.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LVC541ARGYR is the direct equivalent without the G4 suffix, differing primarily in compliance documentation rather than function. Other package variants like SN74LVC541ADWR or SN74LVC541APWR offer identical logical functionality but require different footprints. Cross-package substitution requires careful review of pinout compatibility and thermal performance.
