MAX4547CEE Equivalent & Substitute Parts

Part Overview

The MAX4547CEE is a dual SPDT video switch IC manufactured by Analog Devices Inc./Maxim Integrated, designed for video signal routing and multiplexing applications. This component features a 2-channel configuration with break-before-make switching architecture and operates across a wide supply voltage range of 2.7V to 12V (single supply) or ±2.7V to 6V (dual supply).

The MAX4547CEE is classified as obsolete, which necessitates identification of functionally equivalent alternatives for new designs and ongoing production requirements. The primary substitute maintains identical electrical and mechanical specifications while offering improved product status and compliance certifications.

Engineering Selection Recommendations

The MAX4547CEE+ is the direct functional equivalent for MAX4547CEE applications. Selection between these parts should be based on the following criteria:

For New Designs and Production: MAX4547CEE+ is the appropriate choice. This part maintains active product status with full manufacturer support and carries ROHS3 compliance certification, meeting current regulatory requirements for electronic component procurement.

For Legacy System Maintenance: MAX4547CEE remains available in limited inventory (2100 units) for applications requiring exact original component matching. However, MAX4547CEE+ provides superior long-term availability and compliance posture.

Both parts are electrically and mechanically interchangeable with identical pin assignments, electrical performance, and thermal characteristics. No circuit modifications or design changes are required when transitioning between these variants.
