Correct Answer: As long as the CMOS supply voltage is 5 V, they can be interfaced; however, the fan-out of the CMOS is limited to two TTL gates.
4. Assume a 4-bit parallel in/serial out shift register is loaded with a binary number. How many clock pulses are required after the parallel load has occurred before the first bit in the sequence appears on the serial output line?
7. The gates in this figure are implemented using TTL logic. If the output of the inverter is open, and you apply logic pulses to point B, the output of the AND gate will be ________.
