CD74HC164M 8-Bit Shift Register Equivalent & Substitute Parts

Part Overview

The CD74HC164M is an 8-bit serial-input/parallel-output shift register manufactured by Texas Instruments in a 14-SOIC surface mount package. This logic component converts serial data streams into parallel outputs, functioning as a fundamental building block in digital systems requiring data serialization and timing control.

The CD74HC164M carries a Last Time Buy product status, indicating that Texas Instruments has discontinued active production. This status necessitates identifying functionally equivalent alternatives from active manufacturers to ensure supply chain continuity and long-term design reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74HC164M is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• Logic Type: Shift Register
• Number of Bits per Element: 8
• Function: Serial to Parallel
• Output Type: Push-Pull
• Package / Case: 14-SOIC (0.154", 3.90mm Width)
• Voltage - Supply: 2V ~ 6V

Acceptable Variation Parameters:

• Operating Temperature Range: Minimum -55°C to -40°C; Maximum 85°C to 125°C
• Product Status: Active or Last Time Buy (Obsolete parts require inventory verification)
• Packaging Format: Tube, Tape & Reel, Cut Tape, or Bulk (mechanical handling only)
• Manufacturer: Any qualified semiconductor manufacturer

All substitute parts listed maintain identical functional specifications and pinout compatibility with the CD74HC164M within the 14-SOIC package footprint.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation - Active Status with Extended Temperature Range: CD74HC164M96 (Texas Instruments) and MC74HC164ADR2G (onsemi) are preferred substitutes. Both maintain Active product status, support the full -55°C to 125°C operating temperature range, and carry ROHS3 compliance with MSL 1 rating. CD74HC164M96 provides direct manufacturer continuity from Texas Instruments with Tape & Reel packaging suitable for automated assembly.

Secondary Recommendation - Active Status with Reduced Temperature Range: 74HC164D,653 (Nexperia USA Inc.) and 74HC164S14-13 (Diodes Incorporated) are functionally equivalent alternatives with Active status. Both support -40°C to 125°C operating range, meeting most industrial and commercial applications. These options provide supply diversification across multiple qualified manufacturers.

Fairchild Semiconductor Options: MM74HC164M and MM74HC164MX maintain Active status but operate within -40°C to 85°C range. Selection of these parts requires confirmation that the reduced upper temperature limit (85°C versus 125°C) aligns with application thermal requirements.

Obsolete Status Consideration: NLV74HC164ADR2G (onsemi) carries Obsolete product status. While parametrically equivalent with -55°C to 125°C range, this part should be selected only when existing inventory is confirmed available and long-term supply is not required.

Frequently Asked Questions (FAQ)

Q: Can I directly replace CD74HC164M with any of the listed substitutes? A: Yes, all listed parts are pin-compatible and functionally equivalent within the 14-SOIC package. Electrical performance and logic operation are identical across all substitutes when operating within their specified voltage and temperature ranges.

Q: What is the difference between Tube and Tape & Reel packaging? A: Packaging format affects handling and assembly methodology only. Tube packaging is suitable for manual assembly and lower-volume applications. Tape & Reel packaging is optimized for automated pick-and-place assembly systems. The electronic component itself is identical.

Q: Why do some substitutes have a -40°C minimum temperature instead of -55°C? A: Operating temperature range represents the manufacturer's tested and guaranteed performance envelope. Parts rated -40°C to 125°C are suitable for industrial and commercial applications. Parts rated -55°C to 125°C extend into military and aerospace temperature ranges. Selection depends on application requirements.

Q: Is the CD74HC164M96 a direct replacement for CD74HC164M? A: Yes. CD74HC164M96 is the active production equivalent from Texas Instruments, differing only in packaging format (Tape & Reel versus Tube) and product status (Active versus Last Time Buy). Electrical specifications and pinout are identical.

Q: What does ROHS3 compliance mean for substitution? A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead and other hazardous materials. All listed substitutes maintain ROHS3 compliance, ensuring environmental and regulatory compatibility.

Q: Can I use MC74HC164ADG (Motorola) in high-volume production? A: MC74HC164ADG is available in Bulk packaging, which is typically used for component distribution rather than automated assembly. Confirm packaging availability and handling requirements with your supplier before committing to production volumes.

Q: Should I avoid NLV74HC164ADR2G due to Obsolete status? A: NLV74HC164ADR2G should be selected only if existing inventory is available and your application does not require long-term supply continuity. For new designs or ongoing production, select from Active status alternatives.
