of the device. Also, this pin, in conjunction with the Rx
resistor, determines the internal reference current for the
PD out pin. The voltage range is 2.7 to 5.5 V with respect to
the Gnd pin.

prescaler. The voltage range is 2.7 to 5.5 V with respect to
the Gnd pin. In standby mode, the V CC pin still draws a few
milliamps from the power supply. This current drain can be
eliminated with the use of transistor Q1 as shown in
Figure 21.

than the potential applied to the V DD and V CC pins. The
voltage range for V PD is 2.7 to 5.5 V with respect to the Gnd
pin.
