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 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
±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.
