Notes 4.To measure VOH(CS),insert a 1MΩ 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 VSH,raise VIN
from 4V and measure the input voltage Vm1 when the output goes from H to L and L to H.∆Vs is VSH-VSL.
6. To measure delay time, change VIN from 0V to 5V and compare,with respect to each pin,the positive-going edge observed on a monitor with that
of VIN.To measure response time,change VIN from 5V to 4V and compare,with respect to each pin,the negative-going edge observed on a monitor
with that of VIN.
7.Set the switch to OFF when measuring response time.
