CD4040 12-stage Binary/Ripple Counter
Package SOIC, PDIP, SOP Series CD4000 (CMOS)
CD4040 overview
CD4040 belongs to 4000 Series CMOS Logic Family of Integrated Circuits (IC's) constructed with N- and P-channel enhancement mode transistors. CD4040 has12-stage Binary/Ripple Counter
CD4040 has a supply voltage range of 5V to 20V, which is much higher than any contemporary logic family. It has buffered output which improves transfer characteristics by providing very high gain. All inputs are protected against static discharge with diodes to VDD and VSS.
