CCA stands for common ampere Select one : False or True

The output of the comparator  will be one of three possibilities 0VDC, +5VDC (positive saturation), -5VDC(negative saturation)   If 4 volts is applied to the inverting input of an op amp comparator, and -5 volts is applied to the non-inverting input, the output will be at a __________ volt saturation.

Draw the circuit diagram of a asynchronous counter which can count from 000 to 100.
