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.
The MAX4929E is a low‑frequency 2:1 switch designed for HDMI/DVI applications. It provides a voltage‑clamp function, ±6 kV HBM ESD protection on all I/Os, and can operate from a single 5 V supply or dual/triple supplies. The device is offered in 20‑pin QSOP and 20‑pin 4 mm × 4 mm TQFN packages.
The datasheet includes absolute maximum ratings, electrical characteristics, pin descriptions, timing diagrams, and typical operating curves. It also explains how two MAX4929E devices can be combined to form a 4:1 switch and notes that power‑supply sequencing is not required.
