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

www.DataSheet4U.com 19-1056; Rev 0; 11/07 DVI/HDMI 2:4 Low-Frequency Fan Out Switch 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. ♦ +5V/Drain Switched ♦ HPD (Hot-Plug Detect) Switching ♦ DDC (Display Data Channel) Switching ♦ Direct Entry or I2C Control ♦ Low 1µA Quiescent Current ♦ ±6kV Human Body Model (HBM) ESD Protection on Switch I/Os ♦ Companion IC to the MAX3845 ♦ Provides I2C Control for the MAX3845 ♦ Compact 64-Pin, 10mm x 10mm TQFP Package ♦ Optimized Layout to Support 4:4 or 2:8 Configuration with Two Devices Features MAX4814E Applications Commercial/Industrial HDMI/DVI Switch Boxes High-End Consumer Switchers AV Receivers with Switching PART Ordering Information TEMP RANGE PINPACKAGE 64 TQFP-EP* PKG CODE C64E-10 MAX4814EECB+ -40°C to +85°C +Denotes a lead-free package. *EP = Exposed paddle.

EFN must not be connected to ground. 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 (VDD = +5V ±10%, TA = -40°C to +85°C, unless otherwise noted.
