SpletThe main disadvantage of TTL with a simple output stage is the relatively high output resistance at output logical "1" that is completely determined by the output collector resistor. It limits the number of inputs that can be connected (the fanout ). SpletDisadvantages of TTL serial It features a poor noise margin; hence relatively noisy Secondly, it has relatively high power consumption, especially at high frequencies. Furthermore, a TTL signal has relatively low speed and frequency. TTL vs rs232: What’s the difference? Fig 4: A USB to TTL convertor The two protocols differ in the following ways:
