MAX7432EUD+

Overview

The MAX7432EUD+ is a high-speed, low-power video multiplexer manufactured by Analog Devices Inc. under the Maxim Integrated brand. It integrates four independent 2:1 analog switches within a single TSSOP-14 package. The device supports dual supply voltages of +5V and -5V, enabling it to handle bipolar video signals with rail-to-rail output swing. Key electrical specifications include a bandwidth of 100MHz at -3dB, a settling time of 6ns to 0.1%, and an on-resistance of 18 ohms. It operates with a quiescent current of 10mA per channel and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates four independent 2:1 analog switches for signal routing
• Supports bipolar video signals with rail-to-rail output capability
• Features low on-resistance for minimal signal attenuation
• Operates on dual +/-5V supplies for comprehensive signal handling

Applications

• Video surveillance systems requiring multi-channel input selection
• Medical imaging equipment signal routing
• Test and measurement instrumentation front ends

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure storage conditions adhere to moisture sensitivity level guidelines to maintain package integrity during assembly processes.

Selection Notes

Select this component when designing circuits requiring simultaneous switching of multiple video lines with low distortion. Evaluate power dissipation limits in dense PCB layouts. Consider thermal management strategies if operating near maximum temperature ratings. Verify that the TSSOP-14 footprint matches the target board design constraints.

Part Context

This part belongs to the MAX7432 family of video multiplexers designed for professional video applications. It shares functional similarities with other Maxim video switch ICs but offers specific performance characteristics tailored for high-fidelity signal transmission. The EUD+ suffix indicates a lead-free, RoHS-compliant variant packaged in a thin-shrink small-outline package.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult official Analog Devices cross-reference tools or contact technical support for validated alternatives compatible with the MAX7432EUD+ specifications.
