4016 CMOS analog switch selects 1.5-megohm timing resistor Rt1 when control input line is high, to give negative-going 100-Hz output pulses. When input is low, CMOS switch S2 is on, selecting 1.2-meg-ohm timing resistor Rt2 to give 120-Hz output.-W. G. Jung, IC Timer Cookbook, Howard W. Sams, Indianapolis, IN, 977, p 136-137.
