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.
