4. A CMOS port output is modelled as shown in Figure 3.4(b). It is powered from 5V. The value of RS(high) is estimated to be 120 U and the value of RS(low) 70 U. One port pin will light an LED when it is at Logic 1, and another will light an LED when it is at Logic 0. An LED current of 4 mA is required; for this the LEDs have a forward voltage of 1.8 V. Sketch a circuit showing how each LED is connected and calculate appropriate resistor values.
