CD40102BPWR

Counter Dividers Overview

The CD40102BPWR is a CMOS integrated circuit from the Texas Instruments CD4000B series, housed in a 16-pin TSSOP package. It functions as an 8-stage synchronous down counter configured as two cascaded 4-bit BCD counters. The device features active-low control inputs for clock enable, asynchronous clear, and synchronous or asynchronous preset capabilities. It operates within a supply voltage range of 3 V to 18 V and supports a typical clock frequency of 3.6 MHz at 10 V. The component is rated for industrial temperatures from -55°C to +125°C.

Counter Dividers Feature Summary

• Configured as two cascaded 4-bit BCD counters with a single zero-detect output
• Supports both synchronous and asynchronous preset operations
• Features active-low logic for all control inputs and carry-out signals

Counter Dividers Applications

• Divide-by-N counters
• Programmable timers
• Interrupt timers
• Cycle and program counters

Counter Dividers Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-16 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the specified 3 V to 18 V operating voltage range and industrial temperature limits.

Counter Dividers Selection Notes

Select this component for designs requiring dual-decade BCD counting with synchronous operation. It serves as a direct alternative to the CD40102BMS in surface-mount applications. Verify that the active-low interface logic aligns with the system's control requirements before finalizing the bill of materials.

Counter Dividers Part Context

This part belongs to the CD4000B series of CMOS logic devices, which are standardized for high-voltage operation and wide temperature ranges. The CD40102B variant specifically provides decade counting functionality, distinguishing it from binary counter counterparts like the CD40103B within the same family.

Counter Dividers Replacement Considerations

The CD40102BNSR is a verified pin-compatible replacement offering the same SOIC-16 package and functional specifications.
