HDMI 2:1 Low-Frequency Translating Switch

www.DataSheet4U.com 19-0860; Rev 0; 10/07 HDMI 2:1 Low-Frequency Translating Switch General Description The MAX4929E low-frequency 2:1 switch is ideal for HDMI™/DVI™ switching applications. The device features a voltage clamp function to protect low-voltage systems at the output. The MAX4929E operates with a single 5V supply or dual or triple supplies. The MAX4929E provides clamping and voltage translation without additional components. All external inputs/outputs are electrostatic-discharge (ESD)-protected to ±6kV Human Body Model (HBM). The MAX4929E is available in 20-pin QSOP and 20-pin, 4mm x 4mm, TQFN packages. The device is specified for the extended -40°C to +85°C operating temperature range. o DDC Switches Low 20pF (typ) Capacitance o Protects EDID (Extended Display Identification Data) EPROM or MCU from Excess Voltage o Hot-Plug Detect Signal Translates MCU Voltage to TTL Levels o Two Devices Can Be Used to Form a 4:1 Switch No Added Active Components Needed o ±6kV ESD Protection HBM on All External I/Os o Available in Lead-Free, 20-Pin TQFN or 20-Pin QSOP Packages Features MAX4929E Applications HD Television Receivers HD Monitors High-Resolution Computer Monitors Ordering Information PART TEMP RANGE PINPACKAGE 20 QSOP 20 TQFN-EP* PKG CODE E20-1 T2044-3 MAX4929EEEP+ -40°C to +85°C HDMI is a trademark of HDMI Licensing, LLC.

Note 2: Pullup resistor of RP = 1kΩ at SCLO and SDAO. These resistors are necessary for the clamp/translation to operate correctly. Note 3: Crosstalk is measured between any two analog inputs, crosstalk = 20log(VOUT / VIN). Note 4: Off-isolation = 20log10 (VSCLO / VSCL_), VSCLO = output, VSCL_ = input to off switch. Note 5: Referenced to GND.
