Generally speaking, the starting point of the transition process depends upon the threshold point of the gate in question, and the finishing point of the transition process depends upon the threshold point of the following gate. TTL ICs are usually distinguished by numerical designation as the 5400 and 7400 series. For example, for AND gate when both inputs are true 1, the output is also true 1. Logic gates are used to carry out logical operations on single or multiple binary inputs and give one binary output. 8 0 obj Now connect, in parallel, the remaining 5 inverters to the output of the inverter, and measure the propagation delay of the first inverter again.
