CD40102-Presettable 2-decade BCD down counter
Package DIP Series CD4000 (CMOS)
CD40102 overview
CD40102 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC's) constructed with N- and P-channel enhancement mode transistors. CD40102 has Presettable 2-decade BCD down counter
CD40102 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.
