MC74VHC541DTG

Overview

The MC74VHC541DTG is an octal buffer and line driver manufactured by onsemi, belonging to the VHC logic series. It features eight non-inverting inputs with three-state outputs housed in a 20-pin TSSOP package. The device operates within a supply voltage range of 2.0 V to 5.5 V. Key electrical specifications include a maximum propagation delay of 12 ns at a load capacitance (CL) of 50 pF. Output drive capabilities are rated at 8 mA for both high and low states. The component supports operation across an extended temperature range from -55°C to +125°C.

Feature Summary

• Provides bidirectional data bus buffering between different logic families
• Features three-state outputs to facilitate direct connection to system buses
• Supports wide supply voltage operation from 2.0 V to 5.5 V

Applications

• Bidirectional level translation between CMOS and TTL logic systems
• Memory address and data bus buffering in computing architectures
• Clock distribution and signal buffering in high-speed digital circuits

Procurement Notes

Verify the specific suffix 'DTG' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the ordered quantity matches the standard tube packaging format associated with this surface-mount variant. Cross-reference the date code to verify manufacturing recency and storage conditions prior to installation.

Selection Notes

Select this component when bidirectional bus driving is required with low power consumption. The VHC series offers faster switching speeds compared to standard HC logic while maintaining CMOS input characteristics. Consider the -55°C to +125°C operating range for industrial or automotive environments where wider thermal tolerance is necessary compared to commercial grade parts.

Part Context

This part belongs to the MC74VHC541 family of octal buffers. It serves as a high-performance alternative to older 74HCT or 74HC variants, offering improved speed and lower power dissipation. The device is designed for applications requiring robust signal integrity across varying voltage domains, making it suitable for modern mixed-voltage digital systems.
