6
EN1
Circuit 2 Device enable (active low) w/internal pull-down resistor. A logic High puts device into power-down mode
26
EN2
leaving the logic circuitry active. This state is not recommended for logic control where more than one
MUX-amp share the same video output line.
7
HIZ1
Circuit 2 Output disable (active high) w/internal pull-down resistor. A logic high puts the output in a high
27
HIZ2
impedance state. Use this state when more than one MUX-amp share the same video output line.
