The 4-digit 8-segment digital tube drive circuit is shown in the figure. It is mainly composed of IC1, IC2, IC3 and 4 digital tubes. The display driving
signal is sent to the ICl MSM5512RS circuit. After being processed by Icl, it controls IC2 and IC3 respectively. IC2 outputs the positive polarity control signal of the digital tube
. IC3 outputs the common negative polarity control signal of the digital tube.
