Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD74AC623M96G4 are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Logic Type: Transceiver, Non-Inverting
• Number of Elements: 1
• Number of Bits per Element: 8
• Output Type: 3-State
• Current - Output High, Low: 24mA, 24mA
• Voltage - Supply: 1.5V ~ 5.5V
• Operating Temperature: -55°C ~ 125°C (TA)
• Package / Case: 20-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

Two substitute parts meet these criteria:

1. CD74AC245M96 (Parametric Equivalent) - Active product status, Tape & Reel packaging
2. CD74AC623M (Direct Manufacturer Part) - Active product status, Tube packaging

Both substitutes maintain identical electrical specifications and physical package dimensions, ensuring functional and mechanical compatibility with the obsolete CD74AC623M96G4.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are qualified replacements for the obsolete CD74AC623M96G4 based on complete electrical and mechanical parameter equivalence.

CD74AC245M96 is recommended for new procurement and high-volume applications. This part carries active product status from Texas Instruments and is supplied in Tape & Reel packaging, which is standard for automated assembly processes. Full ROHS3 compliance and unlimited moisture sensitivity rating ensure regulatory and environmental compatibility.

CD74AC623M is recommended for direct replacement in existing designs or lower-volume requirements. This part maintains active product status and is supplied in Tube packaging. It shares identical electrical specifications and package dimensions with the main part, providing seamless functional substitution. Full ROHS3 compliance and unlimited moisture sensitivity rating are maintained.

Both parts are manufactured by Texas Instruments and carry identical compliance certifications (ROHS3, REACH Unaffected, EAR99 ECCN classification).

Frequently Asked Questions (FAQ)

Q: Can CD74AC245M96 be used as a direct replacement for CD74AC623M96G4?

A: Yes. CD74AC245M96 meets all electrical and mechanical requirements. Both devices are 1-element, 8-bit non-inverting transceivers with 3-state output, 24mA output current capability, 1.5V–5.5V supply voltage range, and identical 20-SOIC package dimensions. The primary difference is packaging format (Tape & Reel versus the original packaging) and active product status.

Q: Can CD74AC623M be used as a direct replacement for CD74AC623M96G4?

A: Yes. CD74AC623M is electrically and mechanically identical to CD74AC623M96G4. Both share the same base product number (74AC623), logic type, bit configuration, output characteristics, and 20-SOIC package. The primary difference is packaging format (Tube versus the original packaging) and active product status.

Q: What is the difference between CD74AC245M96 and CD74AC623M?

A: Both parts are functionally equivalent transceivers with identical electrical specifications. The difference lies in the base product number (74AC245 versus 74AC623) and packaging format (Tape & Reel versus Tube). Both are active products from Texas Instruments and meet all parameter requirements for substitution.

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

A: No. All three parts carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected, EAR99 ECCN classification, and Moisture Sensitivity Level 1 (Unlimited). All are suitable for regulated applications.

Q: Which substitute part should be selected for new designs?

A: CD74AC245M96 is recommended for new designs due to its active product status and Tape & Reel packaging, which is optimized for automated assembly. CD74AC623M is suitable if Tube packaging is preferred or if design continuity with the original part number is required.

Q: Are the 20-SOIC packages identical between all three parts?

A: Yes. All three parts use the 20-SOIC package with identical dimensions: 0.295" width, 7.50mm width specification. Pin configuration and footprint are identical, ensuring direct PCB compatibility.
