MC74VHC541DT

Overview

The MC74VHC541DT is an octal buffer and line driver manufactured by onsemi, belonging to the VHC logic family. It features eight non-inverting channels with three-state outputs, designed for surface-mount applications in a TSSOP-20 package. The device operates within a supply voltage range of 2.0V to 5.5V and supports a wide operating temperature range from -55°C to +125°C. Key electrical characteristics include a maximum propagation delay of 12ns at 5V, output drive currents of ±8mA, and low static current consumption typical of CMOS technology.

Feature Summary

• Provides eight non-inverting buffered channels with independent three-state control for bus-oriented memory and clock driving.
• Operates across a wide supply voltage range from 2.0V to 5.5V, ensuring compatibility with various system power rails.
• Features high noise immunity and low power dissipation inherent to advanced CMOS VHC logic technology.
• Supports extended industrial temperature ranges up to 125°C for reliable operation in demanding environments.

Applications

• Bus-oriented architectures requiring isolated data buffering
• Clock distribution networks in high-speed digital systems
• Memory mapping circuits utilizing three-state control

Procurement Notes

Verify the specific suffix 'DT' against official onsemi documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure the ordered component matches the required lead-free status and RoHS compliance specifications defined in the current datasheet revision. Cross-reference the full part number with manufacturer obsolescence notices to confirm active manufacturing status before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring octal buffering with three-state capability within a compact TSSOP-20 footprint. The VHC series offers superior speed compared to standard HC logic while maintaining low power consumption. Consider the extended -55°C to +125°C temperature range if the application involves harsh environmental conditions or industrial equipment standards.

Part Context

This device is part of the broader 74VHC541 family of octal buffers. Variants exist in different packages such as SOIC and SOP, and with different suffixes indicating specific packaging types like tubes or reels. The VHC family represents a performance tier between standard HC and AHCT logic, balancing speed and power efficiency for general-purpose digital interfacing tasks.

Replacement Considerations

Direct pin-compatible alternatives may include the MC74VHC541DTR2G or other VHC-series octal buffers from onsemi. Verify that substitute parts maintain identical voltage ranges, output drive strengths, and package dimensions to ensure seamless integration without circuit redesign.
