For the low power TTL inverter of Figure P7.11, obtain the following: (a) Sketch the VTC. (b) Calculate the maximum fan-out = N = IOL/IIL. (c) Calculate the average power dissipation. Use βF = 90, βR = 0.05, VBE(FA) = VBC(RA) = 0.7 V, VBE(SAT) = 0.8 V, and VCT(SAT) = 0.2 V. Use σo = 0.85 for the output low state.
