Key Parameters

Substitute Part Grouping Explanation

Substitution is strictly based on matching electrical functions, mechanical dimensions, and compliance. Key allowed parameters include: type (magnitude comparator), bit width (4), output logic (active high; functions A<B, A=B, A>B), voltage and current ratings, propagation delay, quiescent current, temperature range, package type and dimensions, mounting style, base product number, RoHS and REACH compliance, and ECCN status. Substitute parts must maintain these specifications as per product category norms.

Parameter Comparison

Engineering Selection Recommendations

Alternative selection for CD74HC85M is based on product status (obsolescence) and matching compliance requirements, including RoHS3, REACH status, and ECCN classification. CD74HC85M96 and 74HC85D,653 both maintain these attributes and feature identical key parameters within the logic IC category, fulfilling mandatory engineering requirements for substitution.

Frequently Asked Questions (FAQ)
