ABSTRACT:
When low-level data is output from a data output terminal, a plurality transistors, whose source-drain paths are inserted in parallel between the data output terminal and a power source terminal, begin to conduct at successively different time-points. Thus, the potential fluctuations produced in the power source voltage are dispersed over time, avoiding circuit component malfunction. Further reduction in noise can be achieved by making the gate drive voltage of the first transistor which conducts in a switching cycle when low-level data is output, smaller than that of the remaining transistors in the switching cycle, so that its current when conducting becomes smaller.
