... The MAX4929E low-frequency 2:1 switch is ideal for HDMI™/DVI™ switching applications. The device fea- tures 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/out- puts are electrostatic-discharge (ESD)-protected to ± ...

... V+ GND applied in any order. Signals can be applied in any order as well. The MAX4929E features a voltage clamp function for the two 2:1 switch. Inputs to SCL_/SDA_ are V+ level compat- ible. Maximum output voltages of SCLO/SDAO are clamped to CLP. For optimum performance connect the EDID EPROM supply voltage to CLP (see Figure 6). For proper operation of the voltage clamp, connect SCLO/SDAO to CLP through the pullup resistors ...
