General Description
The MAX4885 integrates high-bandwidth analog switches and level-translating buffers to implement a complete 1:2 or 2:1 multiplexer for VGA signals. The device provides switching for RGB, display data channel (DDC), and horizontal and vertical synchronization (HSYNC, VSYNC) signals. A low-noise charge pump with internal capacitors provides a boosted gate-drive voltage to improve performance of the RGB switches.

Features
♦ +5V Single-Supply Operation
♦ Programmable Voltage Clamp for Open-Drain DDC Signals
♦ Low 5Ω (typ) On-Resistance (R, G, B Signals)
♦ Low 13pF (typ) On-Capacitance (R, G, B Signals)
♦ Break-Before-Make Switching Protects Against Circuit Shorts
♦ ±8kV HBM ESD Protection on Externally Routed Pins
♦ Low 300µA Supply Current (Lower than 1µA with Charge Pump Disabled)
♦ Space-Saving, Lead-Free, 32-Pin (5mm x 5mm) TQFN Package
