Abstract

PURPOSE:To avoid malfunction by ensuring the reset of C-MOS logic circuit, through the delivery of the reset pulse at the power supply application, even at the momentary interruption of power supply voltage and lowering. CONSTITUTION:After the switch 3 is closed by giving the control power supply between the terminals 1 and 2, while the input voltage e3 of the NAND circuit 10 is lower than the threshold voltage eTH, the circuit 10 is inverted and reset pulse is produced from the output terminal 11. The C-MOS logic circuit connected to the terminals 12 and 13 with this pulseis is initially reset at the same time when the power supply is applied. Next, when the power supply is momentarily interrupted for time t1, the reset pulse is made similarly for eTH>e3, and if the power supply is interrupted for time t2 longer than time t1, the reset pulse is similarly generated for eTH>e3. Further, if the voltage of the power supply 4 is lowered from the normal voltage value for a given rate, the reset pulse is produced. Thus, the C-MOS logic circuit can surely be reset to avoid malfunction.
