MM74HC164MTCX Equivalent & Substitute Parts

Part Overview

The MM74HC164MTCX is an 8-bit serial-in parallel-out shift register manufactured by onsemi, housed in a 14-TSSOP surface mount package. This logic component operates across a 2V to 6V supply voltage range and functions as a serial-to-parallel converter with push-pull output configuration. The part is currently active in production status. Equivalent and substitute parts are necessary when the primary part experiences supply constraints, inventory limitations, or when design flexibility across multiple manufacturers is required for procurement optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MM74HC164MTCX is determined by strict adherence to the following parameters:

Critical Parameters (Must Match Exactly):

• Logic Type: Shift Register
• Function: Serial to Parallel
• Number of Bits per Element: 8 Bit
• Number of Elements: 1
• Output Type: Push-Pull
• Voltage - Supply: 2V ~ 6V
• Package / Case: 14-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount
• Base Product Number: 74HC164

Allowable Variations:

• Operating Temperature range may extend beyond the original specification
• Manufacturer may differ
• Packaging format (Tape & Reel, Cut Tape, Tube) may differ

All substitute parts listed below meet these substitution criteria and maintain electrical and mechanical compatibility with the MM74HC164MTCX.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

MC74HC164ADTR2G (onsemi) offers the highest inventory availability at 125,300 pieces and extends the operating temperature range to -55°C ~ 125°C, providing enhanced thermal performance over the MM74HC164MTCX. This part maintains onsemi manufacturing continuity and ROHS3 compliance.

74HC164PW,118 (Nexperia USA Inc.) provides substantial inventory depth at 18,818 pieces with active product status and extended operating temperature range to -40°C ~ 125°C. This part is available in Cut Tape and Digi-Reel packaging formats.

74HC164T14-13 (Diodes Incorporated) offers active product status with 3,156 pieces in inventory and -40°C ~ 125°C operating temperature range, providing manufacturer diversity for supply chain resilience.

SN74HC164PWR (Texas Instruments) maintains active product status with 2,100 pieces available and -40°C ~ 125°C operating temperature range, supplied in Cut Tape and Digi-Reel packaging.

Secondary Substitutes (Discontinued Status):

SN74HC164PW and SN74HC164PWT (Texas Instruments) are discontinued at DiGi Electronics but remain available in limited quantities (2,000 and 2,027 pieces respectively). These parts are suitable only when existing inventory is confirmed and long-term supply is not required.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical electrical specifications within the 2V ~ 6V supply voltage range.

Frequently Asked Questions (FAQ)

Q: Can I substitute MM74HC164MTCX with MC74HC164ADTR2G?

A: Yes. MC74HC164ADTR2G is a direct functional equivalent with identical logic type, bit configuration, output type, and package specifications. The extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 85°C) provides additional thermal margin and does not create compatibility issues in applications designed for the MM74HC164MTCX.

Q: What is the difference between the various Texas Instruments part numbers (SN74HC164PW, SN74HC164PWR, SN74HC164PWT)?

A: These three Texas Instruments parts are functionally equivalent 8-bit shift registers with identical electrical specifications. The differences are in packaging format: SN74HC164PW is supplied in Tube packaging, SN74HC164PWR in Cut Tape and Digi-Reel format, and SN74HC164PWT in Tape & Reel format. SN74HC164PWR and SN74HC164PWT maintain active product status, while SN74HC164PW is discontinued at DiGi Electronics.

Q: Are all substitute parts in the same 14-TSSOP package?

A: Yes. All substitute parts listed are housed in the 14-TSSOP (0.173", 4.40mm Width) surface mount package, ensuring mechanical and electrical compatibility with the MM74HC164MTCX without PCB redesign.

Q: Which substitute part has the best inventory availability?

A: MC74HC164ADTR2G from onsemi has the highest inventory at 125,300 pieces, followed by 74HC164PW,118 from Nexperia USA Inc. at 18,818 pieces.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All substitute parts listed are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the MM74HC164MTCX.

Q: Can I use a substitute part with an extended operating temperature range in an application designed for -40°C ~ 85°C?

A: Yes. Parts with extended temperature ranges (such as MC74HC164ADTR2G at -55°C ~ 125°C) are fully compatible with applications specified for narrower ranges. The extended range provides additional design margin without creating functional or reliability concerns.
