The cxas4244 is a four channel, bidirectional, SPDT, video analog switch for RGB and hybrid Multiplexing and multiplexing of video signals. Cxas4244 has low on resistance (5 Ω typ), high bandwidth

The cxas4244 is a four channel, bidirectional, SPDT, video analog switch for RGB and hybrid
Multiplexing and multiplexing of video signals. Cxas4244 has low on resistance (5 Ω typ), high bandwidth
(500MHz typ), fast switching time (10.0ns typ) and other excellent performance indexes can guarantee NTSC
The on resistance of the signal (RGB or composite video signal) is small and the gain is stable (DG = 0.6)

The cxas4244 is a four channel, bidirectional, SPDT, video analog switch for RGB and hybrid Multiplexing and multiplexing of video signals. Cxas4244 has low on resistance (5 Ω typ), high bandwidth
