CD4522BNSR

Counter Dividers Overview

The CD4522BNSR is a CMOS programmable BCD divide-by-N counter integrated circuit manufactured by Texas Instruments. It operates within the 4000/14000 logic series and features a synchronous counting mode with a downward count direction. The device is housed in a 16-pin SOIC package and supports a supply voltage range of 3 V to 18 V. It functions as a decade counter with load/preset inputs and is rated for operation between -55 °C and +125 °C.

Counter Dividers Feature Summary

• Programmable BCD divide-by-N functionality
• Synchronous down-counting operation
• Integrated load and preset input capabilities

Counter Dividers Applications

• Frequency division circuits
• Digital timing systems
• Programmable counter applications

Counter Dividers Procurement Notes

Verify the specific suffix 'G4' against the requested part number, as it indicates lead-free status and RoHS compliance. Confirm the SOIC-16 package type matches the design requirements. Ensure the operating temperature range aligns with the intended environment. Check for any specific ordering prefixes or suffixes that may affect availability or specifications.

Counter Dividers Selection Notes

Select this component when a synchronous, downward-counting decade counter is required. It is suitable for designs needing programmable division ratios via BCD inputs. Consider the wide supply voltage range and industrial temperature rating for robust performance. Compare with other members of the 4000/14000 series if alternative pinouts or speeds are needed.

Counter Dividers Part Context

This device belongs to the Texas Instruments CD4000 series of CMOS logic devices. It is functionally similar to the CD4522BNSRG4, which shares the same core specifications but includes RoHS-compliant packaging details. The series is known for low power consumption and high noise immunity in digital logic applications.
