which reduces the input impedance. This also raises the fc value of the HPF formed at the input pin block, so the capacitance of the input
coupling capacitor must be increased according to equation (a). The recommended values for calculation results are listed in the table
below.
time there is no need to change the capacitance of the input coupling capacitor.
When three bias input type models (BH76361FV or BH76363FV) are used in parallel, they can be used for RGB signal switching
applications. Likewise, when one clamp input type model (BH76360FV or BH76362FV) is connected in parallel with two bias input type
models (a total of three ICs used in parallel), they can be used for component signal switching applications. The same method can be used
to determine the capacitance of I/O coupling capacitors of these applications.
When several of these ICs are used, it enables applications in which separate images are output to the car navigation system's front and
When a clamp is used as the input type, the original input impedance becomes much greater, and if two or three are used at the same

When several ICs are used at the same time, the number of parallel connections of input impedance equals the number of ICs being used,
