NOTES:
1. Decrease VCC from 5.0 V to 4.0 V and note the VCC value when VO1 (observed on CRT1) transitions to an abrupt LOW state.
2. Increase VCC from 4.0 V to 5.0 V and note the VCC value when VO1 (observed on CRT1) transitions to an abrupt HIGH state.
3. Increase the Clock voltage (VCLK) from 0 V to 3.0 V and observe the value of VCLK when ICLK transitions to an abrupt increase.
4. Measured with VO0 = 1.0 V.
5. Increase VCC from 0 V to 2.0 V and note the VCC value when VO1 (observed on CRT1) transitions to an abrupt LOW state. The VO1 value
will initially track the VCC voltage increase until the internal circuit bias becomes active, at which time the VO1 value will return to a LOW state.
6. Increase VCC from 0 V to 2.0 V and note the VCC value when VO2 (observed on CRT2) starts to track the VCC voltage.
