CD74HC4050E

Overview

The CD74HC4050E 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. The device utilizes silicon gate technology for fast switching speeds, with typical propagation delays specified at various voltage levels. It supports surface-mount installation in TSSOP-16 packages and offers robust output drive capabilities suitable for interfacing with TTL loads.

Feature Summary

• Provides six independent non-inverting buffering channels for signal transmission
• Capable of level conversion from higher voltage logic inputs to lower voltage outputs
• Features enhanced input protection structures against negative electrostatic discharge

Applications

• Logic level translation between different voltage domains
• Bus driver applications requiring multiple channel buffering
• General-purpose signal buffering in digital circuits

Procurement Notes

Verify the specific suffix 'E' indicates the TSSOP-16 package variant when ordering. Confirm that the required operating temperature range covers -55°C to +125°C for your application environment. Ensure compatibility with the target PCB footprint for the thin-shrink small-outline package before procurement.

Selection Notes

Select this component when six-channel non-inverting buffering is required alongside voltage level shifting capabilities. It serves as an alternative to the inverting CD74HC4049 when phase preservation is necessary. Consider its wide supply voltage range and industrial temperature rating for versatile deployment in mixed-signal systems.

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 provides inverting buffers. Both components share similar electrical characteristics but differ in signal polarity. The CD74HC4050 is designed for applications requiring non-inverted signal transmission across varying logic levels.

Replacement Considerations

The CD74HC4050PWR is a pin-compatible surface-mount alternative in the same family. For inverting buffer requirements, the CD74HC4049 serves as the functional counterpart. Verify package dimensions and lead configurations when substituting between DIP and TSSOP variants.
