MAX310CWN Equivalent & Substitute Parts

Part Overview

The MAX310CWN is a video multiplexer IC manufactured by Analog Devices Inc./Maxim Integrated, designed for video switching applications. This 8:1 multiplexer operates as a single-channel video switch in an 18-SOIC surface mount package. The part is classified as obsolete, making identification of suitable substitutes essential for ongoing system support and new design implementations. Substitute parts must maintain electrical and mechanical compatibility while meeting current compliance requirements.

Substitute Part Grouping Explanation

Substitution of the MAX310CWN is determined by strict equivalence across the following critical parameters:

Multiplexer configuration: 8:1 topology
Channel count: Single channel (1)
On-state resistance: 250 Ohm maximum
Supply voltage ranges: 9V ~ 36V (single) and ±4.5V ~ 18V (dual)
Switching feature: Break-Before-Make functionality
Package format: 18-SOIC surface mount
Operating temperature range: 0°C ~ 70°C

The MAX310CWN+ qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is product status and compliance certification.

Engineering Selection Recommendations

The MAX310CWN+ is the direct functional equivalent of the MAX310CWN. Both parts share identical electrical characteristics and mechanical specifications. The MAX310CWN+ is preferred for new designs and ongoing production due to its active product status and ROHS3 compliance certification. The MAX310CWN, classified as obsolete, should be replaced with the MAX310CWN+ in system redesigns and component refresh cycles. Both parts maintain REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can MAX310CWN+ be used as a direct replacement for MAX310CWN?

A: Yes. Both parts are electrically and mechanically identical. The MAX310CWN+ is the active production equivalent with improved compliance status.

Q: What are the key differences between MAX310CWN and MAX310CWN+?

A: The primary differences are product status (obsolete vs. active) and RoHS compliance (non-compliant vs. ROHS3 compliant). Electrical and mechanical specifications are identical.

Q: Are there any package compatibility concerns?

A: No. Both parts use the 18-SOIC surface mount package with identical dimensions (0.295", 7.50mm width). PCB footprints and assembly processes are interchangeable.

Q: What supply voltage configurations does this multiplexer support?

A: The MAX310CWN and MAX310CWN+ support both single supply (9V ~ 36V) and dual supply (±4.5V ~ 18V) configurations.

Q: Is the break-before-make feature present in both parts?

A: Yes. Both the MAX310CWN and MAX310CWN+ incorporate break-before-make switching functionality.

Q: What is the on-state resistance specification?

A: The maximum on-state resistance for both parts is 250 Ohm.

Q: Are there any temperature range limitations?

A: Both parts operate within the 0°C ~ 70°C temperature range (TA).
