Applications Information
Logic Inputs
The logic control inputs can be driven up to +3.6V regardless of the supply voltage. For example, given a +3.3V supply, the output enables
or select pins may be driven low to 0V and high to 3.6V. Driving the control pin(s) Rail-to-Rail

Switching Waveforms
at Channel X
at Channel Y
Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control.
Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control.
All input impulses are supplied by generators having the following characteristics: PRR ≤ 10 MHz, Z
The outputs are measured one at a time with one transition per measurement.
