Channel 1 input for output amplifier "A"
Not Internally Connected; it is recommended these pins be tied to ground to
minimize crosstalk.

Device enable (active low). Internal pull-down resistor ensures the device will be
active with no connection to this pin. A logic High on this pin puts device into power-
down mode. In power-down mode only logic circuitry is active. All logic states are
preserved post power-down. This state is not recommended for logic control where
more than one MUX-amp share the same video output line.
Device latch enable on the ISL59424. A logic high on LE will latch the last (S0, S1)
logic state. HIZ and ENABLE functions are not latched with the LE pin.
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.
