MC74HC4049D

Inverter Gates Overview

The MC74HC4049D is a hex inverter manufactured by onsemi, designed as a high-to-low level converter within the 74HC series of high-speed CMOS logic devices. It features six independent inverting channels with overvoltage-tolerant inputs capable of withstanding up to 15V, enabling interface between higher voltage logic systems and lower voltage CMOS circuits. The device operates on a supply voltage range of 2.0V to 6.0V and utilizes a 16-pin SOIC (SOT109-1) surface-mount package. It exhibits low static current consumption and robust noise immunity due to its internal three-stage inverter structure.

Inverter Gates Feature Summary

• Provides high-to-low logic level shifting capability through overvoltage-tolerant inputs
• Integrates six independent inverting channels for parallel signal processing
• Ensures stable output performance with high noise immunity via internal circuit design

Inverter Gates Applications

• Converting logic levels from high-voltage sources to low-voltage CMOS systems
• Battery backup circuit interfaces requiring voltage translation
• General-purpose buffering and inversion in mixed-voltage digital environments

Inverter Gates Procurement Notes

Verify the specific manufacturer marking and date code upon receipt, as multiple vendors produce this component. Confirm that the received part matches the exact MC74HC4049D designation to ensure compatibility with onsemi specifications. Check for RoHS compliance status if required by your assembly standards. Ensure storage conditions adhere to moisture sensitivity level guidelines to prevent package damage before reflow soldering.

Inverter Gates Selection Notes

Select this component when interfacing 15V tolerant inputs with standard 5V or 3.3V CMOS outputs. It is suitable for applications requiring buffered inversion with high noise margins. Consider the 16-SOIC package constraints for PCB layout. Verify that the operating temperature range meets the environmental requirements of the final assembly, noting variations between commercial and automotive grades if applicable.

Inverter Gates Part Context

This device belongs to the widely adopted 74HC family of high-speed CMOS logic integrated circuits. It serves as a standard solution for voltage translation tasks where input signals exceed the supply voltage of the receiving logic stage. The component is produced by various semiconductor manufacturers, including Nexperia, NXP, Toshiba, and onsemi, ensuring broad industry availability and interchangeability for basic functional requirements.

Inverter Gates Replacement Considerations

Compatible substitutes include the 74HC4049D from other manufacturers such as Nexperia, NXP, and Toshiba. These parts share identical logical functionality and pinout configurations. Verify that alternative sources meet the same electrical specifications regarding input tolerance and propagation delay before substitution.
