H2).
VoL1, VoL2 Low level output voltage
The condition is as Table. Set SW19 to GND (OPEN), input 0V at
input terminal. Measure the output voltage, the voltage is as VoL1
(VoL2).
Vith1, Vith2 Input selectional voltage
The condition is as table. Set SW19 to GND (OPEN), increasing
gradually the voltage of input terminal from 0V, measure the voltage
of input terminal when output terminal is 4.5V. The input voltage is
as Vith1 (Vith 2).
Trd1, Trd2 Rising delay time
Tfd1, Tfd2 Falling delay time
The condition is as table. Set SW19 to GND (OPEN), SG7 is as the
input signal of input terminal, measure the waveform of output. Ris-
ing delay time is as Trd1 (Trd2). Falling delay time is as Tfd1 (Tfd2).
Reference to the Fig. as shown below.
Vsth1, Vsth2 Switching selectional voltage
1. The condition is as table. SG1 is as the input signal of Pin 2,
Pin5, Pin7, and SG7 is as the input signal of Pin8, Pin9. There is
no input at another pins.
2. Input 0V at Pin19, confirm that there are signals output from
T.P.19, T.P.20, T.P.23, T.P.25, T.P.28, T.P.31.
3. Increase gradually the voltage of terminal Pin19. 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 Pin11, Pin13, Pin16, and SG7 as the
input signal of Pin17, Pin18. There is no input at another pins.
5. Inputs 5V at Pin19, confirm that there is no signal output from
T.P.19, T.P.20, T.P.23, T.P.25, T.P.28, T.P.31.
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.
