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.
