Pin 5 = ground, pin 7 influx current: T4 output
Pin 5 = VCC, pin 7 influx current: T4 output
The pin 5 voltage when the pin 2 output
appears when slowly raising the voltage
applied to pin 5 from 0 V.
The input signal should be 300 mVp-p:
T2 output
The pin 5 voltage when the pin 2 output
appears when slowly lowering the voltage
applied to pin 5 from 5 V.
The input signal should be 300 mVp-p:
T2 output
Stipulated as the output ratio when a
10 mVp-p amplitude sine wave is input to
pin 1: T2 output
Measure the output amplitude when a
300 mVp-p amplitude sine wave is input to
pin 1: T2 output
The V1 level when T1 switches from low to
high when slowly raising V1 from 0 V: T1
output
The V1 level when T1 switches from high to
low when slowly lowering V1 from 5 V: T1
output
With a 2-kΩ load: T1 output
