Substitute Part Grouping Explanation

Substitution of the 74HCT365D,652 is determined by strict equivalence across the following critical parameters:

Logic type and function: Buffer, Non-Inverting
Element and bit configuration: 1 Element, 6 Bit per Element
Output control: 3-State output
Supply voltage compatibility: 4.5V ~ 5.5V
Package form factor: 16-SOIC surface mount
Compliance certifications: ROHS3 Compliant, REACH Unaffected

Substitute parts must maintain identical functional specifications and package dimensions to ensure direct replacement capability. Variations in output current ratings, operating temperature ranges, and product status do not preclude substitution when the core electrical and mechanical parameters align.

Engineering Selection Recommendations

All listed substitute parts maintain functional and electrical equivalence to the 74HCT365D,652 across core parameters. Selection should prioritize active product status for long-term availability and supply chain stability.

MC74HCT365ADR2G (onsemi, Active) and CD74HCT365M96 (Texas Instruments, Active) are recommended for new designs and ongoing procurement due to active product status and confirmed availability. Both parts maintain identical logic configuration, voltage supply range, package form factor, and compliance certifications.

MC74HCT365ADG (onsemi, Obsolete) provides functional equivalence but shares obsolete status with the original part, limiting its utility for long-term supply assurance.

Output current specifications vary between manufacturers: the original part and onsemi variants deliver 6mA output current, while the Texas Instruments variant delivers 4mA. This difference does not affect functional substitution when circuit design accommodates the specified output current rating.

All substitute parts are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance across applications.

Frequently Asked Questions (FAQ)

Q: Can CD74HCT365M96 directly replace 74HCT365D,652 in existing designs?

A: Yes. Both parts share identical logic type, element configuration, output type, voltage supply range, and 16-SOIC package dimensions. The CD74HCT365M96 operates across an extended temperature range (-55°C to 125°C versus -40°C to 125°C) and delivers lower output current (4mA versus 6mA). Verify that circuit design accommodates the 4mA output current specification before substitution.

Q: What is the difference between MC74HCT365ADG and MC74HCT365ADR2G?

A: Both parts are manufactured by onsemi and share identical electrical specifications, including 6mA output current and -55°C to 125°C operating temperature range. The primary difference is packaging: MC74HCT365ADG is supplied in Tube packaging, while MC74HCT365ADR2G is supplied in Tape & Reel (TR) format. MC74HCT365ADR2G maintains active product status, whereas MC74HCT365ADG is obsolete.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts—CD74HCT365M96, MC74HCT365ADG, and MC74HCT365ADR2G—are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance with environmental and hazardous substance restrictions.

Q: Does the 16-SOIC package dimension remain consistent across all substitutes?

A: Yes. All substitute parts use the 16-SOIC package with 0.154" width and 3.90mm width specification, ensuring mechanical compatibility with existing PCB layouts and footprints.

Q: Which substitute part offers the best long-term availability?

A: MC74HCT365ADR2G (onsemi, Active) and CD74HCT365M96 (Texas Instruments, Active) both maintain active product status, providing superior long-term availability and supply chain continuity compared to obsolete alternatives.
