MAX4885E is a 1:2 VGA switch launched by Maxim, with ±15kV HBM ESD protection, 1GHz bandwidth, low 5Ω (typical) On-Resistance (R, G, B signals), low 6pF (typical) On-Capacitance (R, G, B signals), low R, G, B Skew -50ps (typical)
The MAX4885E integrates high‑bandwidth analog switches and level‑translating buffers to provide a 1:2 VGA signal multiplexer. It supports RGB, HSYNC, VSYNC and DDC signals, offering low on‑resistance, low capacitance and near‑zero power consumption, making it suitable for notebook docking stations, digital projectors, monitors and KVM switches.
Key electrical specifications include a 1 GHz bandwidth, typical on‑resistance of 0.5 Ω, typical on‑capacitance of 15 pF, ±15 kV HBM ESD protection on all external pins, operating temperature range –40 °C to +85 °C, and a 24‑pin 4 mm × 4 mm TQFN package. The device operates from a +5 V supply with a quiescent current of about 1 µA.
