Vsth1, Vsth2 Switching Selectional Voltage
1. The condition is as Table. SG1 is as the input signal of pin 2, pin 5, pin 7, and SG7 is as the input signal of pin 8,
pin 9. There is no input at another pins.
2. Input 0 V at pin 19, confirm that there are signals output from T.P.21, T.P.22, T.P.25, T.P.27, T.P.30, T.P.35.
3. Increase gradually the voltage of terminal pin 19. Read the voltage when there is no signal output from the
terminals listed as above.
The voltage is as Vsth1.
4. SG1 as the input signal of pin 11, pin 13, pin 16, and SG7 as the input signal of pin 17, pin 18. There is no input at
another pins.
5. Inputs 5 V at pin 19, confirm that there is no signal output from T.P.21, T.P.22, T.P.25, T.P.27, T.P.30, T.P.35.
6. Decreasing gradually the voltage of terminal pin 19. Read the voltage when there are signals output from the
terminals listed as above. The voltage is as Vsth2.
