Cmos Ic 4011. The proposed timer circuit is dependent on quad 2 input cmos ic 4011 u1. The standard 4000 series cmos ic is the 4011 which includes four independent two input nand gates.
Cd4011 is the most ordinarily utilize metal oxide semiconductor cmos chip. C1 discharges and the near zero voltage at its positive lead is applied to the high impedance inputs of the four gates of ic1 wired in parallel when p2 is momentarily closed. These devices are available from most semiconductor manufacturers such as fairchild semiconductor philips or texas instruments these are usually available in both through hole dil and soic format.
It is unused and in perfect condition.
What is the difference between nand and nor gate. A very long time constant is provided by r1 and c1. It is unused and in perfect condition. Cd4011 is the most ordinarily utilize metal oxide semiconductor cmos chip.
