MC74HC541ADTEL

Overview

The MC74HC541ADTEL is an octal non-inverting buffer and line driver manufactured by onsemi. It features three-state outputs compatible with CMOS, NMOS, and TTL logic families. The device operates within a supply voltage range of 2.0V to 6.0V and supports a wide operating temperature range from -40°C to +125°C. Packaged in a TSSOP-20 surface-mount format, it provides high noise immunity and low input current characteristics typical of advanced CMOS technology.

Feature Summary

• Octal non-inverting buffer design for bus-oriented systems
• Three-state output capability with dual active-low enables
• Wide operating voltage range supporting 2.0V to 6.0V
• Extended industrial temperature rating up to +125°C

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented systems

Procurement Notes

Verify the specific suffix 'ADTEL' against official datasheets to confirm package dimensions and tape/reel specifications. Ensure compatibility with existing PCB footprints for TSSOP-20 packages. Confirm RoHS compliance status for the specific manufacturing lot prior to integration into final assemblies.

Selection Notes

Select this component when designing systems requiring octal buffering with high noise immunity and wide voltage flexibility. It serves as a direct pin-compatible replacement for LS541 devices. Consider the extended temperature range for applications exposed to harsh environmental conditions or high thermal loads.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices. It functions similarly to the MM74HC541 but is branded under onsemi's manufacturing lines. The device is designed to interface directly with various logic families while maintaining low power consumption and high drive capabilities suitable for driving large bus capacitors.

Replacement Considerations

Direct substitutes include the MM74HC541 and generic 74HC541 equivalents from other manufacturers. Verify that alternative sources maintain the same TSSOP-20 footprint and electrical characteristics to ensure seamless integration without redesigning the host circuit board.
