ENABLE

Circuit 2

Device enable (active low). Internal pull-down resistor ensures device is active with no

connection to this pin. A logic High puts device into power-down mode and only the logic

circuitry is active. Logic states are preserved post power-down.

26

HIZ

Circuit 2

Output disable (active high). Internal pull-down resistor ensures the device will be active with no

connection to this pin. A logic high, puts the outputs in a high impedance state. Use this state

to control logic when more than one MUX-amp share the same video output line.
