CD74HCT541M

Overview

The CD74HCT541M is an octal buffer and line driver manufactured by Texas Instruments, belonging to the HCT logic family. It features eight non-inverting inputs and outputs with three-state capability for bus-oriented applications. The device operates within a supply voltage range of 4.5 V to 5.5 V. It utilizes a 20-pin SOIC package suitable for surface-mount technology. Key electrical characteristics include a high-level output current of -6 mA and a low-level output current of 6 mA. The component supports a wide operating temperature range from -55°C to +125°C.

Feature Summary

• Provides eight non-inverting buffers with three-state outputs for efficient bus management
• Compatible with standard TTL logic levels due to HCT series specifications
• Designed for high-temperature operation up to 125°C in industrial environments

Applications

• Bus-oriented memory and address drivers
• Clock distribution circuits
• Data acquisition systems requiring signal buffering

Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to confirm exact package dimensions and tape-and-reel specifications. Ensure the ordering part number matches the required temperature grade and RoHS compliance status as defined in the latest datasheet revision. Cross-reference the manufacturer code to distinguish between original production and authorized contract manufacturing sources.

Selection Notes

Select this component when designing systems that require robust signal buffering across a wide industrial temperature range. The HCT logic compatibility ensures seamless integration with existing TTL-based architectures. Consider the three-state output feature for implementing shared data buses where multiple devices must share communication lines without interference.

Part Context

This device is part of the broader CD74HCT541 family of octal buffers. It shares functional similarities with other SN74HCT541 variants but may differ in packaging or manufacturing origin. The HCT series bridges the performance gap between older TTL technologies and modern CMOS standards, offering improved noise immunity while maintaining compatible input thresholds.
