Title: Semiconductor integrated circuit
Inventor: NISAKA MINORU
IPC: G06F1/24
Filed: 1986-05-02
Abstract: PURPOSE:To reduce the chip size of a LSI by adding plural switch circuits and a switch control circuit to a semiconductor integrated circuit IC to obtain a capacitor needed for an automatic clearing circuit and a noise absorbing circuit. CONSTITUTION:Switch circuits 5 and 6 conduct with application of a power supply VCC and at the same time a transistor 1 also conducts. Then a capacitor 2 starts charging and at the same time an automatic clearing circuit 3 starts its action. The working of the circuit 3 is stopped when the charging of the capacitor 2 is finished. A switch control circuit 8 detects the stop of the circuit 3 and produces the timing signal to set both circuits 5 and 6 under nonconductive states. Then a switch circuit 7 conducts and noise absorbing circuit 4 is connected to the capacitor 2. The capacitor 2 is used to absorb noises out of the key input signal 10. The circuit 3 works only when the power supply VCC is applied with the timing quite different from that of the circuit 4. Thus just a single capacitor 2 can be used by both circuits 3 and 4 under the control of the circuit 8.
