NOTES: A. When the inputs are open circuited, the output is high. A capacitor may be used for dc isolation of the line-terminating resistor.
At the frequency of operation, the impedance of the capacitor should be relatively small.
B. Use of a capacitor to control response time is optional.
Example: let f = 5 MHz
