WebIn high-speed digital circuits, a very important logic gate parameter is propagation delay: the delay time between a change-of-state on a gate’s input and the corresponding change-of-state on that gate’s output. Consult a manufacturer’s datasheet for any TTL logic gate and report the typical propagation delay times published there. WebThe TTL family allows a 2V - 5V difference to be counted as a HIGH and defines the threshold for output for HIGH as 2.7V to 5V. In the CMOS family, an input wanting to define HIGH must bring between 3.5V and 5V. But TTL only has to bring 2.7V, leaving a difference of almost a volt that is valid for TTL and invalid for CMOS.

Websources. Figure TTL-3 shows the situation when a TTL input is driven LOW by the output of another TTL gate. Transistor Q5A in the driving gate is ON, and thereby provides a path to ground for the current flowing out of the diode D1XB in the driven gate. When current flows into a TTL output in the LOW state, as in WebUsing a larger resistor would be possible - the logic threshold for TTL is a minimum of 0.8 volts, but one should remember that the skimpy noise margin of TTL is then eaten into, especially if the switch is distant from the gate. With CMOS logic it is possible to use either configuration with a higher-valued resistor (say 10K).
