CD74HC4050NSR

Overview

The CD74HC4050NSR 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 a maximum low-level output current of 5.2mA and a maximum high-level output current of -5.2mA. Propagation delay varies with voltage, reaching 85ns at 2V, 17ns at 4.5V, and 14ns at 6V. It supports an operating temperature range from -55°C to +125°C.

Feature Summary

• Provides six independent non-inverting buffer channels for signal conditioning
• Capable of translating higher voltage logic levels down to lower voltage logic levels
• Features modified input protection structures to withstand negative electrostatic discharge events

Applications

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

Procurement Notes

Verify the specific suffix NSR indicates the tape-and-reel packaging format when ordering. Confirm that the TSSOP-16 package dimensions align with your PCB footprint requirements. Ensure the component meets RoHS3 compliance standards if required by your manufacturing process. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity.

Selection Notes

Select this component when a hex non-inverting buffer is required for HC logic families. Consider the 2V to 6V operating range for compatibility with various power supplies. Evaluate the propagation delay specifications against your system timing constraints. Verify that the TSSOP package style fits your surface-mount assembly capabilities.

Part Context
