SN74HC164D 8-Bit Shift Register Equivalent & Substitute Parts

Part Overview

The SN74HC164D is an 8-bit serial-input/parallel-output shift register manufactured by Texas Instruments in a 14-SOIC surface mount package. This component functions as a logic shift register with push-pull output, converting serial data input to parallel output across 8 bits. The SN74HC164D is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing production and maintenance applications. Active alternatives from multiple manufacturers provide direct functional replacement while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74HC164D is determined by strict equivalence across the following parameters:

• Logic Type: Shift Register (8-bit, 1 element)
• Function: Serial to Parallel conversion
• Output Type: Push-Pull
• Supply Voltage: 2V ~ 6V
• Package: 14-SOIC surface mount
• Mounting Type: Surface Mount
• Base Product Number: 74HC164 series

All substitute parts listed maintain identical functional specifications and package dimensions. Substitutes are grouped by manufacturer and product status (Active, Discontinued, or Obsolete). Operating temperature range variations are noted but do not prevent substitution in applications within the overlapping temperature window (-40°C ~ 125°C).

Parameter Comparison

Engineering Selection Recommendations

For applications requiring the SN74HC164D, the following selection criteria apply:

Primary Substitutes (Active Status, Full Temperature Range -40°C ~ 125°C):

• SN74HC164DR (Texas Instruments): Direct successor from original manufacturer with highest inventory availability (248,945 pcs). Identical specifications with Cut Tape & Digi-Reel packaging.
• 74HC164D,653 (Nexperia USA Inc.): Manufacturer-recommended substitute with active status and substantial inventory (40,100 pcs). Maintains full temperature range and ROHS3 compliance.
• 74HC164D-Q100J (Nexperia USA Inc.): Automotive-qualified variant (AEC-Q100) for applications requiring automotive-grade components.

Secondary Substitutes (Active Status, Extended Temperature Range -55°C ~ 125°C):

• MC74HC164ADR2G (onsemi): Highest inventory among extended-range options (125,200 pcs). Exceeds standard temperature specification.
• MC74HC164ADG (Motorola): Bulk packaging option with extended temperature range.

Conditional Substitutes (Limited Temperature Range -40°C ~ 85°C):

• MM74HC164M and MM74HC164MX (Fairchild Semiconductor): Suitable only for applications operating within -40°C ~ 85°C window. Not recommended for full temperature range applications.

Avoid:

• NLV74HC164ADR2G (onsemi): Obsolete status limits long-term availability despite current inventory.

Frequently Asked Questions (FAQ)

Q: Can I substitute SN74HC164D with any of the listed parts? A: Yes, all listed parts are functionally equivalent within their specified operating temperature ranges. Selection depends on your application's temperature requirements, packaging preference, and supply chain availability. For applications requiring the full -40°C ~ 125°C range, use SN74HC164DR, 74HC164D,653, or 74HC164D-Q100J.

Q: What is the difference between the various Nexperia part numbers (74HC164D,653 and 74HC164D-Q100J)? A: Both are Nexperia equivalents with identical electrical specifications and full temperature range (-40°C ~ 125°C). The 74HC164D-Q100J includes AEC-Q100 automotive qualification, making it suitable for automotive applications. The 74HC164D,653 is the standard industrial variant. Packaging differs: 74HC164D,653 uses Cut Tape & Digi-Reel, while 74HC164D-Q100J uses Tape & Reel.

Q: Why should I avoid the Fairchild MM74HC164M and MM74HC164MX parts? A: These parts have a reduced operating temperature range (-40°C ~ 85°C) compared to the original SN74HC164D (-40°C ~ 125°C). Use them only if your application operates exclusively within the -40°C ~ 85°C window. For full temperature range compatibility, select alternatives with -40°C ~ 125°C or -55°C ~ 125°C specifications.

Q: What does "Obsolete" status mean for NLV74HC164ADR2G? A: Obsolete status indicates the manufacturer has discontinued production. While current inventory exists (3,169 pcs), future availability is not guaranteed. For new designs or long-term production, select parts with Active status.

Q: Are all these parts ROHS3 compliant? A: Most listed parts are ROHS3 compliant. Fairchild Semiconductor parts (MM74HC164M, MM74HC164MX) do not specify RoHS status in available data. Verify RoHS compliance with your supplier if this is a requirement for your application.

Q: Can I use the extended temperature range parts (-55°C ~ 125°C) as direct replacements? A: Yes. Extended temperature range parts (MC74HC164ADR2G, MC74HC164ADG, NLV74HC164ADR2G) are fully compatible with applications designed for the standard range. The extended range provides additional margin for extreme environment applications.

Q: What packaging options are available? A: Packaging varies by manufacturer: Cut Tape & Digi-Reel (SN74HC164DR, 74HC164D,653), Tape & Reel (MC74HC164ADR2G, 74HC164D-Q100J, NLV74HC164ADR2G), Bulk (MC74HC164ADG), and Tube (original SN74HC164D). Select based on your procurement and assembly requirements.
