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 sig-
nals. 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 out-
puts 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 require-
ment and simplicity in board layout. The MAX4887
operates over the -40°C to +85°C temperature range.
