General 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) on-resistance 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.

ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS
(VDD= +5V ±10%, TA= -40°C to +85°C, unless otherwise noted. Typical values are at TA= +25°C, VDD= +5V. Note 2.)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
