SN74LV541ATRGYR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV541ATRGYR is an octal buffer and driver manufactured by Texas Instruments, designed for operation within a 4.5-V to 5.5-V VCC range. It features eight non-inverting channels with three-state outputs, housed in a 20-VQFN package measuring 3.5x4.5 mm. The device supports mixed 3.3-V/5-V system environments, allowing inputs to be driven by either voltage level. It includes an Ioff circuit to disable outputs during power-down, preventing destructive current backflow. Operating temperatures range from -40°C to 125°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides eight-channel buffering with three-state output capability for bus driving applications.
• Supports mixed 3.3-V and 5-V system environments through TTL-voltage compatible inputs.
• Integrates Ioff circuitry to prevent destructive current backflow when the device is powered down.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'TRGYR' corresponds to the 20-VQFN (3.5x4.5) package and tape-and-reel packaging configuration. Confirm that the 4.5-V to 5.5-V supply voltage requirement aligns with the target system design, as this variant differs from lower-voltage LVC series options. Ensure thermal management strategies account for the specified operating temperature range of -40°C to 125°C.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 5-V logic family buffer is required for high-speed data transmission or clock distribution. The choice is appropriate for designs needing isolation between input sources and output loads while maintaining compatibility with both 3.3-V and 5-V signaling standards. Consider the VQFN package size constraints and thermal dissipation requirements relative to alternative surface-mount packages.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LV541A family of octal buffers and drivers. It shares functional similarities with other devices in the LV and LVC series but is specifically optimized for 5-V operation. The family is commonly used in digital logic circuits requiring signal amplification and direction control across multiple lines simultaneously.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitute part numbers include SN74LV541APWR and SN74LVC541ARGYR. Verify pinout compatibility and voltage specifications before substitution, as LVC variants operate at different supply voltages compared to the LV series.
