MAX4929E 19-0860 Rev 0 10/07 HDMI 2:1 Low-Frequency Translating Switch General Description Features The MAX4929E low-frequency 2:1 switch is ideal for DDC Switches HDMI/DVI switching applications. The device fea- Low 20pF (typ) Capacitance tures a voltage clamp function to protect low-voltage Protects EDID (Extended Display Identification systems at the output. The MAX4929E operates with a single 5V supply or dual or triple supplies. The Data) EPROM or MCU from Excess Voltage MAX4929E provides clamping and voltage translation Hot-Plug Detect Signal without additional components. All external inputs/out- Translates MCU Voltage to TTL Levels puts are electrostatic-discharge (ESD)-protected to 6kV Human Body Model (HBM). Two Devices Can Be Used to Form a 4:1 Switch No Added Active Components Needed The MAX4929E is available in 20-pin QSOP and 20-pin, 4mm x 4mm, TQFN packages. The device is specified 6kV ESD Protection HBM on All External I/Os for the extended -40C to +85C operating temperature Available in Lead-Free, 20-Pin TQFN or 20-Pin QSOP range.
