CD74HC164ME4 Equivalent & Substitute Parts

Part Overview

The CD74HC164ME4 is an 8-bit serial-input/parallel-output shift register manufactured by Texas Instruments in a 14-SOIC surface mount package. This component is classified as Last Time Buy, indicating limited availability from the original manufacturer. The shift register converts serial data input into parallel output across 8 bits, operating at supply voltages between 2V and 6V with a push-pull output configuration. Due to its Last Time Buy status, identifying qualified substitute parts is essential for design continuity and long-term component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC164ME4 is determined by strict equivalence across the following parameters: 8-bit shift register configuration, serial-to-parallel function, push-pull output type, 2V to 6V supply voltage range, 14-SOIC package geometry, and surface mount mounting type. All substitute parts listed maintain these core electrical and mechanical specifications. Packaging format (tube, tape & reel, or bulk) does not affect functional equivalence but may impact procurement and handling. Operating temperature range variations are noted where they differ from the original part. RoHS and REACH compliance status are provided for regulatory assessment.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement of the CD74HC164ME4, the CD74HC164M96 from Texas Instruments is the primary recommendation. Both parts share identical electrical specifications and RoHS3 compliance, with the substitute offering Active product status and higher inventory availability in tape & reel packaging.

The MC74HC164ADR2G from onsemi provides an alternative with Active status, ROHS3 compliance, and the highest inventory level (125,200 pcs). This part maintains the full operating temperature range of -55°C to 125°C and is suitable for applications requiring extended temperature performance.

The 74HC164D,653 from Nexperia USA Inc. and 74HC164S14-13 from Diodes Incorporated are both Active products with substantial inventory. Both operate across the full 2V to 6V supply range and maintain ROHS3 compliance. The Nexperia part supports -40°C to 125°C, while the Diodes part also operates to -40°C minimum.

The MM74HC164M and MM74HC164MX from Fairchild Semiconductor are Active alternatives with the same 2V to 6V supply specification. However, these parts have a reduced operating temperature range of -40°C to 85°C, making them suitable only for applications not requiring the full -55°C to 125°C performance envelope of the original part.

The NLV74HC164ADR2G from onsemi is classified as Obsolete and should be avoided for new designs despite its availability.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for the CD74HC164ME4?

A: All listed substitute parts maintain the core functional specifications: 8-bit shift register, serial-to-parallel conversion, push-pull output, 2V to 6V supply voltage, and 14-SOIC package. However, operating temperature range varies. Parts with -40°C to 85°C ratings (MM74HC164M, MM74HC164MX) are not suitable if your application requires the full -55°C to 125°C range of the original part.

Q: What is the difference between packaging formats (Tube, Tape & Reel, Bulk)?

A: Packaging format affects handling, storage, and automated assembly compatibility but does not alter electrical performance. Tube packaging is suitable for manual handling and small quantities. Tape & reel format is optimized for pick-and-place assembly equipment. Bulk packaging is typically used for high-volume procurement. Select based on your manufacturing process requirements.

Q: Why is the CD74HC164ME4 marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments is discontinuing this part. Existing inventory is limited, and no further production is planned. Transitioning to an Active substitute part ensures long-term component availability for future production runs and design revisions.

Q: Are all substitute parts RoHS3 compliant?

A: Most substitute parts listed are ROHS3 compliant. The MM74HC164M, MM74HC164MX, and MC74HC164ADG do not specify RoHS status in the provided data. Verify RoHS compliance with the manufacturer if regulatory certification is required for your application.

Q: Which substitute offers the best inventory availability?

A: The 74HC164S14-13 from Diodes Incorporated has the highest inventory level at 128,980 pcs, followed by MC74HC164ADR2G from onsemi at 125,200 pcs. Both are Active products with full RoHS3 compliance and suitable for immediate procurement.
