Note 1: The KEY input equivalent circuit is shown to the right. When the

control pin is open, the input is pulled up to a high level

(approximately 1.4 V). This applies the channel A input signal

to the output. A low level changes the output to the channel B

input signal.

Note 2: This value measured with a capacitor connected between the

input terminal and ground. See Figure 7.

Note 3: This value measured with a 5 kΩ resistor and series capacitor

connected between the input terminal and ground. See Figure

8.

Note 4: Power dissipation is 200 mW when mounted as recommended.

Derate at 1.6 mW/°C for operation above 25 °C.
