The NCS6433 is a wide bandwidth, bidirectional, Quad 2:1, NMOS-based video switch suitable for dealing with video signals such as RGB, composite, S-Video, and component video (YPbPr). The NCS6433 is controlled by a single switch-enabled (OE) input. When OE is low the switch is enabled and the A port is connected to the B port. When OE is high the switch is disabled and the high-impedance state exists between the A and B ports. The line select (SEL) input controls the data path of the multiplexer/demultiplexer. The NCS6433 has a wide bandwidth, low crosstalk, low on resistance, and fast switching times making it suitable for high-frequency video applications in high definition LCD TV's.
