DVI/HDMI 2:4 Low-Frequency Fan Out Switch
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 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.
