Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74HC258N,652 is determined by the following critical parameters:

• Circuit configuration (4 x 2:1 multiplexer)
• Output current specifications (7.8mA high and low)
• Supply voltage range (2V ~ 6V minimum compatibility)
• Package type (16-DIP through-hole)
• Mounting compatibility (through-hole)

The identified substitute parts maintain these core electrical and mechanical parameters, ensuring functional equivalence in circuit applications. Variations in operating temperature range, product status, and compliance certifications are noted but do not affect core substitutability within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

SN74HC258N (Texas Instruments) is the primary recommended substitute. This part maintains all critical electrical parameters and package specifications while offering active product status, ensuring long-term availability and manufacturer support. RoHS3 compliance aligns with modern manufacturing standards. The operating temperature range of -40°C ~ 85°C covers standard industrial applications, though designs requiring the full -40°C ~ 125°C range should verify thermal requirements.

CD74HC257E (Harris Corporation) provides functional equivalence with an extended operating temperature range (-55°C ~ 125°C) suitable for extreme environment applications. However, this part is obsolete and RoHS non-compliant, limiting its use to legacy system maintenance or specialized applications where extended temperature performance is critical.

Selection between substitutes should prioritize application requirements for product availability, compliance certifications, and operating temperature specifications.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC257E replace the 74HC258N,652 in new designs?

A: The CD74HC257E maintains electrical and mechanical compatibility but is obsolete and RoHS non-compliant. New designs should use the SN74HC258N for long-term support and regulatory compliance.

Q: What is the difference between the 74HC257 and 74HC258 base product numbers?

A: Both are 4 x 2:1 multiplexers with identical electrical specifications. The CD74HC257E uses the 74HC257 base designation while the NXP and TI parts use 74HC258. These are functionally equivalent within the 74HC logic family.

Q: Does the SN74HC258N operate across the full -40°C ~ 125°C temperature range?

A: The SN74HC258N operates from -40°C to 85°C. Applications requiring operation above 85°C must verify thermal performance or consider the CD74HC257E, which extends to 125°C.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 16-DIP (0.300", 7.62mm) package with identical through-hole mounting, ensuring direct board-level substitution.

Q: What is the significance of RoHS compliance for this component?

A: RoHS3 compliance indicates the part meets restrictions on hazardous substances. The SN74HC258N and 74HC258N,652 are compliant, while the CD74HC257E is not. Compliance is required for most commercial and industrial applications.
