74HC4050D,653

Overview

The Nexperia 74HC4050D,653 is a hex non-inverting buffer with overvoltage tolerant inputs, designed for HIGH-to-LOW level shifting applications. It operates on a supply voltage range of 2.0 V to 6.0 V and features inputs tolerant up to 15 V. The device utilizes CMOS technology for low power dissipation and high noise immunity. It is housed in a 16-lead SO plastic small outline package (SOT109-1) suitable for surface mounting. The component supports an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Overvoltage tolerant inputs allow interfacing with signals up to 15 V while powered by lower voltages.
• Non-inverting logic function provides direct signal transmission without phase inversion.
• CMOS construction ensures low power consumption and high noise immunity.
• ESD protection exceeds 2000 V per Human Body Model and 1000 V per Charged Device Model.

Applications

• HIGH-to-LOW level shifting between different logic families
• Digital buffering in mixed-voltage systems
• Signal translation interfaces

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 74HC4050 family includes alternative packages like TSSOP. Confirm the temperature grade corresponds to the application environment, noting that the 'D' suffix indicates the extended industrial range. Ensure compliance with JEDEC standards relevant to the target system voltage requirements before finalizing procurement.

Selection Notes

Select this component when non-inverting buffering with high input voltage tolerance is required. The 15 V input tolerance makes it suitable for driving lower voltage CMOS circuits from higher voltage sources. Consider the 16-pin SO package constraints regarding board space and thermal dissipation. Verify that the static and dynamic characteristics meet the system's speed and load requirements.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices manufactured by Nexperia. The 74HC4050 specifically functions as a hex buffer, distinct from inverters or gates within the same logic family. It is designed to bridge voltage domains, allowing safe interface between 15 V logic levels and standard 2 V to 6 V CMOS supplies.

Replacement Considerations

The 74HC4050PW is a pin-compatible alternative using a TSSOP16 package. Other manufacturers may offer equivalent hex buffers with similar overvoltage tolerances, but verification of electrical parameters and pinout compatibility is required.

FAQ

What is the maximum input voltage the 74HC4050 can tolerate?

The inputs are overvoltage tolerant up to 15 V, regardless of the supply voltage.

Does the 74HC4050 invert the input signal?

No, it is a non-inverting buffer; the output follows the input state directly.

What is the recommended supply voltage range?

The recommended operating supply voltage (VCC) ranges from 2.0 V to 6.0 V.
