Description
The MAX4887 triple, high-frequency switch is intended for notebooks and monitors to permit RGB signals to be switched from one driver to one of two loads (1:2) or one of two sources to be connected to one load (2:1). The MAX4887 high-performance switch utilizes n-channel architecture with internal high-drive pullup from a low-noise charge pump, resulting in very low on-capacitance.
The MAX4887 features 5Ω(typ) on-resistance switches with 10pF on-capacitances for routing RGB video signals. A logic input enables or disables the internal charge pump for optimal frequency performances when operating at lower input voltages resulting in standby supply current less than 3µA. All RGB inputs/outputs are ESD protected to ±8kV Human Body Model (HBM) and feature a global input (EN-bar) that places all inputs and outputs in a high-impedance state.
The MAX4887 is available in a small 3mm x 3mm, 16-pin TQFN package for ease of assembly and flowthrough layout, resulting in minimum space requirement and simplicity in board layout. The MAX4887 operates over the -40°C to +85°C temperature range.
