CD4522 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC’s) constructed with N- and P-channel enhancement mode transistors. CD4522 has been Programmed, BCD Divide-by-N Counter
CD4522 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.
CD4522 Features
- Internally synchronous for high internal and external speeds.
- Logic edge-clocked design increments on positive Clock transition or on negative Clock Inhibit transition.
- Standard Symmetrical Output Characteristics
