There are 10 digital tubes and 10 74HC164s. 74HC164 is an 8-bit serial-input and parallel-output shift register. These 10 74HC164s are probably used for static driving of 10-bit digital tubes. As for other chips, it is impossible to guess without the electrical schematic. Details Published on 2020-9-5 18:45
