Description

The MAX4814E high-definition multimedia interface (HDMI) switch provides routing for low-frequency signals. The MAX4814E operates from a single +5.0V ±10% supply voltage and is ideal for connecting multiple HDMI sources to multiple loads.

The MAX4814E is a bidirectional 2:4 HDMI™ switch. Each switch consists of five single-pole/single-throw (SPST) channels. Two channels have a low 3Ω (typ) onresistance to route +5V and drain (ground return), and three channels to route data. The device features a mode input to control the device through an I²C interface or direct-control logic inputs.

The MAX4814E is available in a 64-pin (10mm x 10mm) TQFP package and operates over the -40°C to +85°C extended temperature range.
