MM74HC164MTC Equivalent & Substitute Parts

Part Overview

The MM74HC164MTC is an 8-bit parallel-in/serial-out shift register manufactured by onsemi, housed in a 14-TSSOP surface mount package. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The shift register performs serial-to-parallel conversion with push-pull output configuration, operating across a 2V to 6V supply voltage range and -40°C to 85°C temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MM74HC164MTC is determined by strict equivalence across the following parameters: logic type (shift register), bit configuration (8-bit), function (serial-to-parallel conversion), output type (push-pull), supply voltage range (2V ~ 6V minimum), package type (14-TSSOP), and mounting method (surface mount). All identified substitute parts maintain these core electrical and mechanical specifications. Packaging format variations (tube, cut tape, tape & reel) do not affect functional compatibility but may impact procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring the MM74HC164MTC, the following substitutes are recommended based on product status and compliance:

Primary Selection: MC74HC164ADTR2G (onsemi) or 74HC164PW,118 (Nexperia USA Inc.) are preferred due to active product status and extended operating temperature range (-55°C ~ 125°C and -40°C ~ 125°C respectively), providing superior thermal margin over the original part's -40°C ~ 85°C specification. Both maintain ROHS3 compliance and REACH unaffected status.

Secondary Selection: SN74HC164PWR (Texas Instruments) offers active product status with -40°C ~ 125°C operating range and ROHS3 compliance, suitable for applications within standard industrial temperature ranges.

Inventory Consideration: MC74HC164ADTR2G provides the highest inventory availability (125300 Pcs), supporting volume production requirements. 74HC164PW,118 offers substantial inventory (18818 Pcs) with active status.

All substitute parts share identical electrical specifications (2V ~ 6V supply, push-pull output, 8-bit serial-to-parallel function) and mechanical compatibility (14-TSSOP package, surface mount configuration).

Frequently Asked Questions (FAQ)

Q: Can MM74HC164MTC be directly replaced with any of these substitutes? A: Yes. All listed substitutes maintain identical logic function, bit configuration, output type, supply voltage range, and 14-TSSOP package specification. Direct pin-for-pin replacement is supported without circuit modification.

Q: What is the difference between packaging formats (tube, cut tape, tape & reel)? A: Packaging format affects procurement and assembly handling only. Tube packaging suits manual assembly; cut tape and tape & reel formats support automated pick-and-place equipment. Electrical and mechanical specifications remain identical across all packaging options.

Q: Why does MC74HC164ADTR2G have a wider operating temperature range? A: MC74HC164ADTR2G operates from -55°C ~ 125°C compared to MM74HC164MTC's -40°C ~ 85°C. This extended range provides additional thermal margin for demanding applications but does not affect compatibility in standard operating conditions.

Q: Are all substitutes RoHS3 compliant? A: Yes. All substitute parts listed maintain ROHS3 compliance and REACH unaffected status, matching the original MM74HC164MTC certification requirements.

Q: Which substitute offers the best availability? A: MC74HC164ADTR2G provides the highest inventory level at 125300 Pcs, followed by 74HC164PW,118 at 18818 Pcs. Both are suitable for volume production.
