MM74HC4050MTC Equivalent & Substitute Parts

Part Overview

The MM74HC4050MTC is a non-inverting buffer logic IC manufactured by onsemi, designed for 6-element buffering applications with push-pull output configuration. This device operates across a 2V to 6V supply voltage range and is housed in a 16-TSSOP surface mount package. The part is currently listed as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution for the MM74HC4050MTC is determined by strict equivalence across the following critical parameters:

Logic type and function: Buffer, Non-Inverting with 6 elements, 1 bit per element
Output configuration: Push-Pull topology
Output current capability: 5.2mA high and low
Supply voltage range: 2V ~ 6V minimum requirement
Package type: 16-TSSOP surface mount form factor
Base product number: 74HC4050

All substitute parts listed maintain identical functional specifications and package geometry, ensuring direct replacement capability in existing PCB designs. Variations in operating temperature range, product status, and packaging format (tube, tape & reel, cut tape) do not affect electrical substitutability but may impact procurement and application requirements.

Engineering Selection Recommendations

For applications currently using the MM74HC4050MTC, the following selection criteria apply:

Active Product Status Priority: The 74HC4050PW,118 (Nexperia) and CD74HC4050PWR (Texas Instruments) are both active products with full manufacturing support and extended operating temperature ranges (-40°C to 125°C and -55°C to 125°C respectively), providing superior long-term availability and design flexibility compared to the obsolete original part.

Compliance Considerations: All substitute parts from Texas Instruments and Nexperia carry ROHS3 compliance certification, meeting modern environmental and regulatory requirements. The original MM74HC4050MTC does not specify RoHS status.

Temperature Range Expansion: Substitute parts from Texas Instruments (CD74HC4050PW, CD74HC4050PWR, CD74HC4050PWT) extend the lower operating temperature limit to -55°C, providing enhanced performance margin for industrial and automotive applications requiring extended temperature operation.

Packaging and Procurement: Selection between substitute parts depends on procurement format requirements. Tape & Reel packaging (74HC4050PW,118 and CD74HC4050PWT) suits high-volume manufacturing. Cut Tape with Digi-Reel (CD74HC4050PWR) accommodates mixed-volume orders. Tube packaging (CD74HC4050PW) supports lower-volume requirements.

Frequently Asked Questions (FAQ)

Q: Can the 74HC4050PW,118 directly replace the MM74HC4050MTC in existing designs?

A: Yes. Both parts share identical logic function, output configuration, current ratings, supply voltage range, and 16-TSSOP package geometry. No circuit modifications are required for direct substitution.

Q: What is the significance of the extended operating temperature range in Texas Instruments parts?

A: The CD74HC4050PW, CD74HC4050PWR, and CD74HC4050PWT extend operation to -55°C minimum, compared to -40°C for the original part. This provides additional thermal margin for applications in cold environments or with stringent temperature specifications. The upper limit of 125°C also exceeds the original 85°C specification.

Q: Are all substitute parts electrically identical?

A: Yes. All substitute parts maintain the same 5.2mA output current, 2V to 6V supply voltage range, and 6-element non-inverting buffer configuration. Differences in product status, temperature range, and packaging format do not affect electrical performance or pin compatibility.

Q: Which substitute part should be selected for new designs?

A: The CD74HC4050PWR (Texas Instruments, active status) or 74HC4050PW,118 (Nexperia, active status) are recommended for new designs due to active product status and extended operating temperature ranges. Both ensure long-term availability and design support.

Q: Does packaging format affect electrical performance?

A: No. Tube, Tape & Reel, and Cut Tape formats are packaging and delivery methods only. They do not alter electrical specifications, performance, or functionality. Selection should be based on procurement volume and manufacturing process requirements.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts from Texas Instruments and Nexperia are ROHS3 compliant. The original MM74HC4050MTC does not specify RoHS status. For applications requiring RoHS compliance, substitute parts from these manufacturers are required.
