CD40161BPWR

Counter Dividers Overview

The CD40161BPWR is a synchronous programmable 4-bit binary counter manufactured by Texas Instruments. It operates within the 4000/14000/40000 series of CMOS logic devices and utilizes a TSSOP-16 surface-mount package. The component supports an upward counting direction with a maximum operating frequency of 2 MHz at nominal supply voltage. It features a load/preset input capability and requires a power supply range between 3 V and 18 V. The device functions reliably across an extended temperature range from -55 °C to 125 °C.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting operation with positive edge triggering
• Programmable preset functionality for direct data loading
• Wide operational voltage range supporting diverse system requirements
• Extended industrial temperature rating for harsh environments

Counter Dividers Applications

• Digital timing sequences and event counters
• Frequency division circuits in clock management systems
• Address generation for memory or I/O decoding
• Control logic for digital state machines

Counter Dividers Procurement Notes

Verify the specific suffix BPWR against the manufacturer's official datasheet to confirm the TSSOP-16 package type and lead-free RoHS compliance status. Ensure that the ordering information matches the exact functional specifications required for the design, as suffixes may indicate variations in packaging or material composition rather than electrical performance changes.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit binary counter is required with programmable preset capabilities. It is suitable for designs needing wide voltage tolerance and high-temperature stability. Consider the TSSOP-16 package constraints for PCB layout and ensure the system clock frequency remains within the specified 2 MHz limit for reliable operation.

Counter Dividers Part Context

This part belongs to the Texas Instruments CD4000 series of CMOS logic integrated circuits. These devices are widely used in general-purpose digital applications due to their low power consumption and compatibility with standard logic families. The CD40161 variant specifically provides binary counting functions, distinguishing it from other series members like shift registers or gates.

Counter Dividers Replacement Considerations

Compatible substitutes include the CD40161BCN and CD40161BE, which offer similar binary counting functionalities. Verify pinout compatibility and electrical characteristics before substitution to ensure seamless integration into existing circuit designs without requiring schematic modifications.
