The CD4022BPWRG4 is a 9-stage ripple carry binary counter part of the CMOS 4000 family. It was designed for applications that require low power, high speed clock logic and is used in many hand-held devices and other applications. The CD4022BPWRG4 application field is in logic, counters, dividers and other functions. The working principle of the CD4022BPWRG4 is that of a ripple-carry binary counter.

The CD4022BPWRG4 consists of four individual divide-by-2 counter blocks. Each block has four flip-flops and a two-input OR gate. When the clock pulse is low, the block will reset and all four outputs are at logic low. When the clock signal is high, the block is enabled and the output sequence is triggered. The block will cycle through the 8-bit code and continue cycling through until the reset is selected. The output sequence can be chosen by connecting the appropriate pins.

The power supply of the CD4022BPWRG4 consists of two pins, VDD and VSS. VDD is the positive power supply terminal which must be driven from a voltage supply that is between 3V and 15V. VSS is the negative power supply terminal and it should be connected to the system\'s common ground. The CD4022BPWRG4 is capable of supplying up to 20mA of current from VDD and up to 200mA from VSS.

The CD4022BPWRG4 has four active-high inputs: CLOCK, CLEAR, PARITYCHECK, and INTEROVERFLOW. CLOCK is the input signal used to clock the counter. CLEAR is an active-high input signal used to reset the counter to all logic low. PARITYCHECK is an active-high input signal used to detect odd or even count and to generate the appropriate PARITYCHECK output signal. INTEROVERFLOW is an active-high input signal used to detect overflow and to generate the appropriate INTEROVERFLOW output signal.

The CD4022BPWRG4 has eight active-high outputs: Qa-Qh. Qa and Qh are the two most significant outputs of the counter and the other six outputs, Qb-Qg, represent the remaining bits. The outputs can be wired to either one or two output loads. When wiring to two output loads, series resistors should be added in order to reduce the output loading. In addition, the FIRSTOUTpin indicates the first output of the counter and the LASTOUTpin indicates the last output of the counter.

The CD4022BPWRG4 is a versatile part that is suitable for use in many applications requiring logic and counting circuits. Its wide power supply range, low power consumption, and good performance make this part suitable for consumer devices, toys, and other manufactured products.
