Circuit 2
Gain Set. Set to logic high for gain of x2 (+6dB), or set to logic low for a gain of x1 (0dB). If
left floating, an internal pull-down resitor pulls this pin low (300k pull-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.
During high impedance state, there is a 2k
Ω pull-down present at each output. If left floating,
an internal pull-down resistor pulls this pin low (300k pull-down).
