Also, for most technologies the optimum fanout for such buffers generally varies from 2.7 to 5.3. A fan out of 4 is the answer to the canonical problem stated as follows: Given a fixed size inverter, small in comparison to a fixed large load, minimize the delay in driving the large load. See more In digital electronics, Fan-out of 4 is a measure of time used in digital CMOS technologies: the gate delay of a component with a fan-out of 4.

WebDerivation of delay in a logic gate. Delay is expressed in terms of a basic delay unit, τ = 3RC, the delay of an inverter driving an identical inverter without any additional capacitance added by interconnects or other loads; the unitless number associated with this is known as the normalized delay. (Some authors prefer define the basic delay unit as … WebIn digital circuitry, fan-out is a measure of the maximum number of digital inputs that the output of a single logic gate can feed without disrupting the circuitry's operations. Most transistor-to-transistor logic ( TTL) gates can support up to 10 other digital gates or devices. Thus, a typical TTL gate has a fan-out of 10.
