MC74VHC541DWR2G

Overview

The MC74VHC541DWR2G is an octal buffer and line driver manufactured by onsemi, belonging to the VHC logic series. It features eight non-inverting inputs and outputs housed in a 20-pin TSSOP package. The device operates within a supply voltage range of 2V to 5.5V, supporting low-voltage applications. It provides three-state outputs with a maximum output current of 8mA for both high and low states. The component exhibits a propagation delay of 12ns and functions reliably across an extended temperature range from -55°C to 125°C.

Feature Summary

• Octal configuration providing eight independent non-inverting signal paths
• Three-state output capability enabling bus-oriented system designs
• Extended operating temperature range suitable for demanding environments

Applications

• Bus-oriented architectures requiring signal buffering
• Clock distribution networks
• Memory module data line drivers

Procurement Notes

Verify the specific suffix DWR2G against official datasheets to confirm the TSSOP-20 package and tape-and-reel orientation. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles defined in the manufacturer's handling guidelines before integration into production workflows.

Selection Notes

Select this component when designing systems requiring wide voltage operation down to 2V combined with robust thermal performance up to 125°C. The VHC series offers superior speed compared to standard HC logic while maintaining CMOS power efficiency, making it suitable for portable and industrial applications.

Part Context

This part belongs to the MC74VHC541 family of octal buffers. It serves as a non-inverting variant within the broader 74-series logic ecosystem, specifically optimized for high-speed, low-power applications. The device complements other logic families by bridging different voltage domains in mixed-signal circuit designs.

Replacement Considerations

Direct substitutes include the MC74VHC541DTG (TSSOP package) and the MC74VHCT541ADWR2G (TTL-compatible input thresholds). Verify pinout compatibility and electrical characteristics such as propagation delay and drive strength when evaluating alternative sources.
