BH7659S / BH7659FS
The BH7659S / BH7659FS are input signal switching ICs developed for high resolution displays that have three fc =
250MHz wide-band video switching circuits for RGB video signal switching and four CMOS analog switching circuits for
switching between H
D
and V
D
signals as well as I
