Working Principles

The CD4522BPWRE4 is a CMOS logic IC that functions as a decade counter/divider. It counts in a BCD sequence, with the ability to reset to zero using the MR (Reset) input. The clock inputs (CP1 and CP0) control the counting operation, while the enable input (ENP) enables or disables the counting process. The outputs (QA, QB, QC, QD) represent the BCD count, with active-low logic levels.

Detailed Application Field Plans

The CD4522BPWRE4 can be used in various applications, including:

1. Digital frequency dividers
2. Time delay circuits
3. Event counters
4. Industrial automation systems
5. Electronic voting machines

Detailed and Complete Alternative Models

Some alternative models to the CD4522BPWRE4 include:

1. CD4017BE: Decade Counter/Divider with 10 decoded outputs
2. CD4022B: Octal Counter/Divider with 8 decoded outputs
3. CD4510B: Binary Up/Down Counter with synchronous reset

These alternative models offer similar functionality but may have different pin configurations and specifications.
