MAX4814E 19-1056 Rev 0 11/07 DVI/HDMI 2:4 Low-Frequency Fanout Switch General Description Features The MAX4814E high-definition multimedia interface +5V/Drain Switched (HDMI) switch provides routing for low-frequency sig- HPD (Hot-Plug Detect) Switching nals. The MAX4814E operates from a single +5.0V DDC (Display Data Channel) Switching 10% supply voltage and is ideal for connecting multi- 2 Direct Entry or I C Control ple HDMI sources to multiple loads. Low 1A Quiescent Current The MAX4814E is a bidirectional 2:4 HDMI switch. Each 6kV Human Body Model (HBM) ESD Protection switch consists of five single-pole/single-throw (SPST) on Switch I/Os channels. Two channels have a low 3 (typ) on-resis- Companion IC to the MAX3845 tance to route +5V and drain (ground return), and three 2 Provides I C Control for the MAX3845 channels to route data. The device features a mode 2 input to control the device through an I C interface or Compact 64-Pin, 10mm x 10mm TQFP Package direct-control logic inputs. Optimized Layout to Support 4:4 or 2:8 Configuration with Two Devices The MAX4814E is available in a 64-pin (10mm x 10mm) TQFP package and operates over the -40C to +85C extended temperature range.

EFN must not be connected to ground. DD 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. ELECTRICAL CHARACTERISTICS (V = +5V 10%, T = -40C to +85C, unless otherwise noted.
