MM74HC4050M

Buffers, Drivers, Receivers, Transceivers Overview

The MM74HC4050M is a hex non-inverting logic level down converter manufactured by onsemi. It utilizes advanced silicon-gate CMOS technology and features a modified input protection structure that allows the input voltage to exceed the supply voltage, enabling high-level logic translation to low-level logic while operating from a lower supply. The device operates within a wide power supply range of 2V to 6V. It provides a typical propagation delay of 8ns and supports a fanout of 10 LS-TTL loads. The component is housed in a 16-lead Small Outline Integrated Circuit (SOIC) package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Modified input protection structure enables input voltages to exceed the supply voltage for logic level translation
• Converts high-level logic signals to low-level logic while operating from a lower supply voltage
• Compatible with standard CD4050BC pinout and functionality

Buffers, Drivers, Receivers, Transceivers Applications

• Converting 0–15V CMOS logic to 0–5V logic
• Logic level translation between different voltage domains
• General purpose buffer or inverter applications without level translation

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer origin as the datasheet indicates Fairchild Semiconductor documentation, which may have been acquired by onsemi. Confirm the specific package variant matches the required footprint. Ensure the ordering code suffix aligns with the desired tape and reel configuration if applicable. Cross-reference the part number with current distributor catalogs to confirm availability and exact specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing circuits with significantly different voltage levels, such as translating 15V signals to 5V systems. It is suitable for designs requiring a wide operating voltage range and high noise immunity. Consider the package type based on board space constraints and thermal requirements. Verify compatibility with existing logic families and ensure the input voltage does not exceed absolute maximum ratings.

Buffers, Drivers, Receivers, Transceivers Part Context

The MM74HC4050 belongs to the HC logic family, known for high-speed CMOS operation similar to LS-TTL but with lower power consumption. It is functionally compatible with the CD4050BC. The device is designed for applications requiring robust input protection and reliable signal conversion across varying supply voltages.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The MM74HC4050 is pin and functionally compatible with the CD4050BC. When substituting, verify that the alternative device supports the same input voltage exceeding the supply capability and maintains equivalent propagation delays and output drive characteristics.
