4:1 RGB Dual Gain Video MUX
Connecting the MUX inputs and outputs in parallel allows the
8 channel ISL59483 to be used as a 4:1 RGB MUX with
selectable gains of 1 or 2 (Figure 10). In this example, the high
input impedance of the MUX enables each input video line to
be shared by any number of MUX input pins. The gain select
logic function is created by providing complememtary logic to
the HIZ1 and HIZ2 pins. Channels CH0 through CH3 are
selected by connecting the MUX 1 and MUX 2 S0-1, 2 and
S1-1, 2 channel select inputs together to form channel select
(S0 and S1), as shown in the truth table in Figure 10.
