2. While monitoring each output by Vm4 or CRT, measure the input voltage Vm1 when the output goes from H

from H to L and L to H.

∆V

3. To measure delay time, change VIN from 0 V to 5 V and compare, with respect to each pin, the positive-going

4. Set the switch to OFF when measuring response time.
