Figure P17.23 shows an improved version of the DTL circuit. One offset diode is replaced by transistor

Question:

Figure P17.23 shows an improved version of the DTL circuit. One offset diode is replaced by transistor $Q_{1}$, providing increased current drive to $Q_{o}$. Assume $\beta=20$ for both transistors.

(a) For $v_{X}=v_{Y}=5 \mathrm{~V}$, determine the currents and voltages listed in the figure.

(b) Calculate the maximum fanout for the low output condition.
