CIRCUIT
DESCRIPTION
Circuit 3 Output of amplifier C1
Circuit 3 Output of amplifier B1
Circuit 4A Negative power supply #1 and #2
Circuit 3 Output of amplifier A1
Circuit 4A Positive Power Supply #1 and #2
Circuit 2
Device enable (active low) with internal pull-down resistor. A logic High puts device into power-down
mode 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.
Circuit 2
Output disable (active high) with internal pull-down resistor. A logic high puts the output in a high
impedance state. Use this state when more than one MUX-amp share the same video output line.
