74HC4050DB,118

Overview

The Nexperia 74HC4050DB,118 is a hex non-inverting buffer featuring over-voltage tolerant inputs rated up to 15 V. It operates on a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device utilizes the SO16 plastic small outline package (SOT109-1) with a body width of 3.9 mm. Propagation delay ranges from 14 ns to 22 ns at 6.0 V, while transition times vary between 13 ns and 19 ns under similar conditions.

Feature Summary

• Provides high noise immunity and CMOS low power dissipation characteristics.
• Features overvoltage tolerant inputs capable of handling signals up to 15 V for level shifting applications.
• Includes robust ESD protection exceeding 2000 V via Human Body Model and 1000 V via Charged Device Model.
• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B standards.

Applications

• HIGH-to-LOW level shifting in digital circuits
• Buffering logic signals with high noise immunity requirements
• General purpose buffering within industrial or automotive environments

Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the 74HC4050 family includes variants such as TSSOP16. Confirm the temperature grade aligns with system requirements, noting that this part supports extended industrial temperatures up to +125 °C. Ensure compliance with RoHS directives and check for any recent product change notices regarding packaging or assembly updates before finalizing procurement.

Selection Notes

Select this component when interfacing 15 V logic sources with lower voltage systems requiring non-inverted outputs. The wide supply voltage range accommodates various standard logic families. Consider the SO16 package dimensions if board space allows, as alternative packages like TSSOP are available for different footprint constraints. Verify input leakage current specifications against strict low-power design limits.

Part Context

This device belongs to the 74HC series of high-speed CMOS logic products manufactured by Nexperia. It serves as a fundamental building block for signal conditioning and routing in complex electronic designs. The 74HC4050 specifically addresses the need for level translation without inversion, distinguishing it from standard buffers that lack overvoltage tolerance.

Replacement Considerations

The 74HC4050PW,118 offers identical electrical functionality but utilizes a TSSOP16 package instead of the SO16 form factor. Designers must verify pinout compatibility and physical footprint differences when substituting these parts. Other generic hex buffers lacking 15 V input tolerance are not suitable replacements for level-shifting tasks.
