Simple CMOS linear front end for 5-MHz battery-operated counterreduces power drain and makes it proportional to input frequency,With no input,drain is only a few microamperes Half of COUNTER MC14583 CMOS Schmitt trigger forms front end operating from single 6-V battery used In counter,Upper frequency limit is about 3 MHz,and input sensitivity is 400 mV．-D Aldridge,CMOS Counter Circuitry,Slashes Battery Power Requirements,EDN Magazine,Oct,20,1974,p 65-71.
