Negative Supply Voltage. Bypass V
capacitors as close to the device as possible with the smaller value capacitor closest to the device.
Noninverting Differential Select Input. Setting SEL = high and SEL = low (differential high) enables all four
channels to operate asynchronously. Setting SEL = low and SEL = high (differential low) enables all four
channels to operate in synchronous mode.
Inverting Differential Select Input
Inverting Differential Clock Input. A rising edge on CLK (and falling on CLK) transfers data from the inputs to
the outputs when SEL = differential low.
Noninverting Differential Clock Input
Noninverting Differential Output Enable Input. Setting EN = high and EN = low (differential high) enables the
outputs. Setting EN = low and EN = high (differential low) drives the output low.
