CD74AC164M Equivalent & Substitute Parts

Part Overview

The CD74AC164M is an 8-bit shift register logic IC manufactured by Texas Instruments in a 14-SOIC surface mount package. This component performs serial-to-parallel data conversion with push-pull output configuration, operating across a supply voltage range of 1.5V to 5.5V and temperature range of -55°C to 125°C. The CD74AC164M is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74AC164M is determined by strict equivalence across the following critical parameters:

• Logic type and function (Shift Register, Serial to Parallel conversion)
• Bit configuration (1 Element, 8 Bits per Element)
• Output type (Push-Pull)
• Electrical specifications (Supply voltage 1.5V ~ 5.5V, Operating temperature -55°C ~ 125°C)
• Physical package (14-SOIC with 0.154" width, 3.90mm)
• Mounting type (Surface Mount)
• Compliance certifications (ROHS3, REACH Unaffected)

The CD74AC164M96 qualifies as a direct substitute based on identical electrical and mechanical parameters. The primary difference is packaging format: the main part is supplied in Tube packaging, while the substitute is supplied in Tape & Reel (TR) format. Both parts share the same base product number (74AC164) and are manufactured by Texas Instruments.

Parameter Comparison

Engineering Selection Recommendations

The CD74AC164M96 is a direct functional and electrical equivalent to the CD74AC164M. Both parts maintain identical electrical performance specifications, compliance certifications, and physical package dimensions. The CD74AC164M96 is currently in active production status, whereas the CD74AC164M is discontinued, making the CD74AC164M96 the appropriate selection for new designs and ongoing component procurement.

The packaging difference (Tube versus Tape & Reel) does not affect component functionality or performance. Selection between these formats depends on assembly process requirements and volume considerations. Tape & Reel packaging is standard for automated pick-and-place assembly operations, while Tube packaging is suitable for manual assembly or lower-volume applications.

Frequently Asked Questions (FAQ)

Q: Can the CD74AC164M96 be used as a direct replacement for the CD74AC164M?

A: Yes. Both parts are electrically and mechanically identical. They share the same base product number (74AC164), manufacturer (Texas Instruments), and all critical parameters including supply voltage, operating temperature range, output type, and 14-SOIC package dimensions.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging supplies components in plastic tubes suitable for manual handling and lower-volume assembly. Tape & Reel packaging supplies components on continuous carrier tape wound on reels, optimized for automated surface mount assembly equipment. Both formats contain the same component with identical electrical specifications.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the CD74AC164M and CD74AC164M96 carry identical RoHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level 1 (Unlimited) ratings.

Q: Why is the CD74AC164M discontinued?

A: The CD74AC164M is listed as discontinued at DiGi Electronics. The CD74AC164M96 remains in active production and serves as the current production equivalent.

Q: Are pin configurations identical between these parts?

A: Yes. Both parts use the 14-SOIC package with identical pin assignments and electrical characteristics.
