MAX4887 - Triple Video Switch

General 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).

Key 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) that places all inputs and outputs in a high-impedance state. The MAX4887 is available in a small 3mm x 3mm, 16pin TQFN pac.

MAX4887 19-3972; Rev 0; 2/06 Triple Video Switch General 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 lownoise 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.
