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.
