CD74HC4050MT

Overview

The CD74HC4050MT is a high-speed CMOS logic hex non-inverting buffer manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 6V and features six independent channels in a 16-pin TSSOP package. The device provides standard output drive capabilities with maximum low-level output current of 5.2mA and maximum high-level output current of -5.2mA. Propagation delay varies from 85ns at 2V to 14ns at 6V. It supports an operating temperature range from -55°C to +125°C.

Feature Summary

• Hex non-inverting buffer configuration for signal conditioning
• High-speed CMOS technology with modified input protection structure
• Capable of level conversion from higher voltage logic to lower voltage logic
• Wide operating temperature range suitable for industrial environments

Applications

• Logic level translation between different voltage domains
• Bus driver applications requiring multiple channel buffering
• Signal buffering in high-speed digital circuits
• Interface circuits connecting LSTTL loads to CMOS sources

Procurement Notes

Verify the specific suffix MT indicates the TSSOP-16 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the component matches the exact part number CD74HC4050MT to guarantee pinout and electrical characteristics align with design requirements. Check for obsolescence notices as manufacturing statuses may change.

Selection Notes

Select this component when six non-inverting buffers are required in a compact surface-mount package. It is suitable for designs needing level shifting from up to 16V inputs down to 2V-6V logic levels. Consider the propagation delay specifications relative to the system clock speed. Verify that the TSSOP-16 footprint fits the PCB layout constraints compared to SOIC or DIP alternatives.

Part Context

This part belongs to the Texas Instruments HC series of high-speed CMOS logic devices. It is functionally related to the CD74HC4049, which offers inverting buffers with similar level-shifting capabilities. Both devices share the same silicon technology and protection structures but differ in logical polarity. The CD74HC4050 is designed for general-purpose buffering and voltage translation tasks in digital systems.

Replacement Considerations

CD74HC4049MT serves as a functional substitute if inverting logic is acceptable. CD54HC4050 variants offer military-grade temperature ranges but may require different packaging verification. Cross-manufacturer equivalents like HEF4050B exist but may have different electrical parameters and should be validated against specific application requirements.
