General Description

The MAX4814E high-definition multimedia interface

(HDMI™) switch provides routing for low-frequency sig-

nals. The MAX4814E operates from a single +5.0V

±10% supply voltage and is ideal for connecting multi-

ple 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) on-resis-

tance 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 I

C 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.
