PURPOSE:To control the holding circuit without external connection, by connecting one data output, at least, of the control circuit, where the address input and the data output of the memory are input and output to the logical operation circuit, to the address input side. CONSTITUTION:Input signal converting part 3 converts the input signal such as a switch turn-on and off signal to an IC-level signal and outputs it as address signals A1-An of memory element 1. Data outputs D1-Dn of memory element 1 are converted to the signal of a driving part level from the IC level by output signal converting part 4 to drive the solenoid and so on. Output D0 of memory element 1 is connected directly to input address A0 to form a holding circuit. |
