CD4522BM

Counter Dividers Overview

The CD4522BM is a CMOS programmable BCD divide-by-N counter integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 18 V and supports synchronous counting modes with both up and down direction capabilities. The device features a 4-bit binary-coded decimal architecture housed in a 16-pin SOIC package, designed for applications requiring precise frequency division or time-base generation.

Counter Dividers Feature Summary

• Supports programmable BCD divide-by-N functionality for flexible frequency division ratios
• Enables synchronous counting operations with selectable up or down direction control
• Provides load/preset input capability for direct initialization of the count state

Counter Dividers Applications

• Frequency divider circuits
• Time-base generators
• Digital clock systems

Counter Dividers Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and temperature rating. Ensure compatibility with system voltage levels and logic families. Confirm RoHS compliance status through current manufacturer declarations before procurement integration.

Counter Dividers Selection Notes

Select this component when a synchronous BCD counter with bidirectional counting is required. Compare pinout compatibility with existing designs. Verify that the SOIC package dimensions fit the available PCB real estate constraints.

Counter Dividers Part Context

This part belongs to the CD4000B series of high-speed CMOS logic devices. It shares functional similarities with other counters like the CD4520 but offers specific BCD decoding and programmability features tailored for divide-by-N applications within industrial and consumer electronics.

Counter Dividers Replacement Considerations

Check for CD4522BNSRG4 as a potential alternative variant. Verify pin compatibility and electrical specifications before substitution.
