The MAX4929E is a low-frequency 2:1 switch 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 HDMI/DVI switch designed for applications such as HD television receivers, HD monitors, and high‑resolution computer monitors. It provides voltage‑clamp protection, ESD protection up to +6 kV HBM, and operates from a single 5 V supply or dual/triple supplies.
Key features include low 20 pF typical input capacitance, DDC switching, hot‑plug‑detect translation, and the ability to form a 4:1 switch with two devices without additional active components. The device is offered in 20‑pin QSOP and 20‑pin 4 mm × 4 mm TQFN packages and is specified for an operating temperature range of –40 °C to +85 °C.
