CD40103BPW

Counter Dividers Overview

The CD40103BPW is an 8-stage binary down-counter integrated circuit manufactured by Texas Instruments, belonging to the 4000B series of CMOS logic devices. It features a serial/parallel input capability and supports asynchronous preset and synchronous count operations triggered on the rising edge of the clock signal. The device operates within a supply voltage range of 3V to 18V and provides complementary outputs for each stage. Designed for surface-mount applications, it utilizes a 16-pin TSSOP package and ensures reliable performance across an extended industrial temperature range from -55°C to +125°C.

Counter Dividers Feature Summary

• Supports both serial and parallel data loading modes for flexible configuration
• Provides complementary Q and Q-bar outputs for all eight counting stages
• Features asynchronous preset functionality for immediate initialization
• Operates reliably with high noise immunity typical of CMOS technology

Counter Dividers Applications

• Digital frequency division circuits
• Event counting systems
• Timing sequence generation modules
• Address decoding networks

Counter Dividers Procurement Notes

Verify the specific suffix 'PW' confirms the TSSOP-16 surface mount package variant rather than through-hole options. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the ordering part number matches the exact pinout and electrical specifications required for your design integration.

Counter Dividers Selection Notes

Select this component when an 8-bit down-counting function with parallel load capability is required in a compact surface-mount form factor. Consider the wide operating voltage range suitable for various logic families. Evaluate the propagation delay characteristics against your system's maximum clock frequency requirements to ensure timing integrity.

Counter Dividers Part Context

This component is part of the extensive CD4000B family of standard CMOS logic ICs produced by Texas Instruments. These devices are widely recognized for their compatibility with standard TTL logic levels at lower voltages and their robust performance in general-purpose digital applications. The 4000B series offers a broad selection of gates, flip-flops, and counters for diverse electronic designs.

Counter Dividers Replacement Considerations

Check for direct equivalents such as the CD40103BE or other variants within the same 4000B series that may offer different packaging options like DIP while maintaining identical logical functionality and pin configurations.
