CD74HC4050EG4

Overview

The CD74HC4050EG4 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 lines driving corresponding outputs. The device utilizes TSSOP-16 surface-mount packaging and supports an operating temperature range from -55 °C to +125 °C. Electrical characteristics include a maximum low-level output current of 5.2 mA, a maximum high-level output current of -5.2 mA, and a typical static current of 2 µA. Propagation delay varies with voltage, reaching 85 ns at 2 V, 17 ns at 4.5 V, and 14 ns at 6 V.

Feature Summary

• Provides level translation capabilities for converting higher voltage logic signals down to lower voltage logic levels.
• Features modified input protection structures designed to withstand negative electrostatic discharge events.

Applications

• High-to-low voltage level conversion in mixed-signal systems
• General-purpose buffering for digital signal lines
• Bus driver applications requiring non-inverted signal transmission

Procurement Notes

Verify the specific suffix 'EG4' against the manufacturer's official documentation to confirm RoHS compliance status and exact package variant. Ensure the ordering part number matches the required tape-and-reel or cut-tape configuration for your assembly process. Cross-reference the datasheet revision date to validate electrical parameters before finalizing procurement specifications.

Selection Notes

Select this component when a non-inverting buffer is required for HC-series logic families. It is suitable for designs needing wide temperature operation and robust input protection. Consider the TSSOP-16 footprint constraints and verify that the 2 V to 6 V supply range aligns with the system power architecture.

Part Context

This device belongs to the CD74HC4050 series of high-speed CMOS logic buffers. It serves as the non-inverting counterpart to the CD74HC4049 inverter buffer. Both devices share similar construction techniques but differ in signal polarity and specific level-shifting configurations within the Texas Instruments logic portfolio.

Replacement Considerations

The CD74HC4050PWR is a verified pin-compatible alternative within the same series offering identical logical functionality and electrical specifications.
