Notes 4.To measure V
OH
(CS),insert a 1M
resistor between the CS pin and GND.
5. While monitoring each output by Vm4 or CRT,measure the input voltage Vm1 when the output goes from H to L and L to H.Regarding V
SH
,raise V
IN
from 4V and measure the input voltage Vm1 when the output goes from H to L and L to H.
Vs is V
SH
-V
SL
.
6. To measure delay time, change V
IN
from 0V to 5V and compare,with respect to each pin,the positive-going edge observed on a monitor with that
of V
IN
.To measure response time,change V
IN
from 5V to 4V and compare,with respect to each pin,the negative-going edge observed on a monitor
with that of V
IN
.
7.Set the switch to OFF when measuring response time.
