CD74HC4050M

Overview

The CD74HC4050M is a high-speed CMOS logic hex non-inverting buffer manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and features six independent input-output channels in a 16-pin SOIC package. The device provides balanced propagation delays, with typical values of 85 ns at 2 V, 17 ns at 4.5 V, and 14 ns at 6 V. It supports low-level output currents of 5.2 mA and high-level output currents of -5.2 mA. The component functions effectively as a logic level converter, capable of translating higher voltage inputs down to lower logic levels while maintaining signal integrity across an industrial temperature range.

Feature Summary

• Functions as a hex non-inverting buffer for signal transmission
• Capable of converting high-level logic voltages to lower logic levels
• Features modified input protection structures against negative electrostatic discharge

Applications

• Logic level translation from high voltage domains to low voltage domains
• Bus driving applications requiring standard or bus driver outputs
• General buffering of digital signals in CMOS logic circuits

Procurement Notes

Verify the specific suffix 'M' corresponds to the SOIC-16 package configuration required for your design. Confirm that the operating voltage range of 2 V to 6 V aligns with your system's power supply rails. Ensure compatibility with the HC logic family specifications regarding noise immunity and propagation delay characteristics for your target application frequency.

Selection Notes

Select this component when a non-inverting buffer is needed for level shifting between different voltage domains. It is suitable for applications requiring moderate drive strength and wide operating temperature ranges. Consider the SOIC-16 package constraints for PCB layout. Verify that the input voltage limits do not exceed the maximum ratings defined in the datasheet for safe operation.

Part Context

This part belongs to the CD74HC4050 series of high-speed CMOS logic devices. It is functionally related to the CD74HC4049, which offers inverting buffer capabilities. Both components share similar manufacturing technologies and protection structures, allowing them to be used interchangeably in buffering roles where inversion polarity differs. They are designed to replace older logic families with improved power consumption and speed characteristics.

Replacement Considerations

CD74HC4049M serves as the inverting equivalent within the same series.
