MAX4814EECB+

Video Processing Overview

The MAX4814EECB+ is a bidirectional 2:4 DVI/HDMI low-frequency fanout switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5.0V ±10% supply voltage and provides routing for low-frequency signals in HDMI/DVI applications. The device features five SPST channels per switch, with two channels having a typical on-resistance of 3 Ω to route +5V and drain, and three channels with a typical on-resistance of 12 Ω to route data. It supports I²C or direct-control logic inputs, offers ±6kV HBM ESD protection on switch I/Os, and operates over an extended temperature range of -40°C to +85°C.

Video Processing Feature Summary

• Dual control modes via I²C interface or direct-entry logic inputs
• Integrated Hot-Plug Detect (HPD) and Display Data Channel (DDC) switching capabilities
• Low quiescent current consumption with ±6kV Human Body Model ESD protection

Video Processing Applications

• Commercial and industrial HDMI/DVI switch boxes
• High-end consumer video switchers
• AV receivers with integrated switching functionality

Video Processing Procurement Notes

Verify the component authenticity through authorized distributors or official manufacturer channels. Confirm that the ordering suffix matches the lead-free package specification and ensure the operating temperature range aligns with your system requirements. Cross-reference the pin configuration and electrical characteristics with the latest official datasheet before integration.

Video Processing Selection Notes

Select this component when designing systems requiring low-frequency signal routing for HDMI or DVI interfaces. Ensure the design accommodates the +5V supply requirement and utilizes the appropriate control mode (I²C or direct logic). Consider the 64-pin TQFP package dimensions for PCB layout constraints and verify compatibility with companion ICs like the MAX3845 if full HDMI signal switching is required.
