STMUX7000QTR

STMUX7000 7-channel MUX/DEMUX for analog video signal Features ■ Low RON: 4.0 Ω typical ■ VCC operating range: 3.0 to 3.6 V ■ Enhanced ESD protection: > 8 kV (contact) and 8 kV (HBM) ■ Channel on capacitance: 7.8 pF typical ■ Designed for VGA signal switching ■ Integrated switches for RGB, HSYNC, VSYNC and DDC signals ■ Very low crosstalk: -45 dB at 250 MHz ■ > 1000 MHz -3 dB typical bandwidth (or data frequency) ■ Low power mode for minimum power consumption ■ Package: QFN32L Applications ■ Audio/video switching QFN32 (3 x 6 mm) Description The STMUX7000 is a 7-channel multiplexer/demultiplexer low RON bidirectional designed for analog video signal, such as VGA. It is designed for very low crosstalk, and high bandwidth to maintain high signal integrity. The analog video signal multiplexed from one of two selected sources in the notebook and docking station while the unselected switch goes to Hi-Z status. The device is also protected against high ESD that supports up to 8 kV contact on all I/O pins. The device can be put into low power mode consuming minimum power. Table 1.
