CD4522BPW

Counter Dividers Overview

The CD4522BPW is a CMOS programmable BCD divide-by-N counter manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 18 V and features a synchronous counting mode with a downward count direction. The device is housed in a 16-pin SOIC package and supports load/preset inputs for configuration. It is designed for industrial temperature ranges, functioning reliably between -55°C and +125°C. The component belongs to the 4000/14000/40000 logic series and includes a maximum operating frequency of 1.5 MHz at nominal supply.

Counter Dividers Feature Summary

• Supports programmable BCD divide-by-N functionality via external resistor or capacitor connections
• Features synchronous operation with a dedicated clock input and clear function
• Includes load and preset capabilities for flexible initialization states

Counter Dividers Applications

• Frequency division circuits requiring specific integer ratios
• Programmable timing generators using RC networks
• Digital counters in control systems

Counter Dividers Procurement Notes

Verify the exact suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure the ordering part number matches the required RoHS compliance status and lead time specifications provided by authorized distributors. Cross-reference the pinout diagram with your PCB footprint design to prevent installation errors.

Counter Dividers Selection Notes

Select this component when a synchronous BCD counter with programmable modulus is required. Consider the 3 V to 18 V operating range for compatibility with various logic families. Verify that the 1.5 MHz maximum frequency meets your system clock requirements. Check if the SOIC-16 package fits your board space constraints compared to alternative packages like TSSOP.

Counter Dividers Part Context

This device is part of the standard 4000-series CMOS logic family, known for high noise immunity and wide power supply flexibility. It serves as a fundamental building block for digital timing and counting applications. The 'B' suffix typically denotes improved performance characteristics over earlier generations within the same logical architecture.

Counter Dividers Replacement Considerations

Check for direct equivalents such as the CD4522BM96 or other variants within the CD4522B series. Verify pin compatibility and electrical parameters before substitution. Alternative manufacturers may offer compatible parts under different naming conventions.
