CD74HC40103M96

Counter Dividers Overview

The CD74HC40103M96 is an 8-bit synchronous binary down counter from Texas Instruments, part of the 74HC logic family. It features a single circuit with positive-edge triggered flip-flops and operates within a supply voltage range of 2 V to 6 V. The device supports both synchronous and asynchronous preset functions, along with an asynchronous master reset input. Designed for surface-mount applications, it utilizes a 16-SOIC package and maintains functionality across an extended industrial temperature range from -55°C to +125°C.

Counter Dividers Feature Summary

• Supports cascading operations via terminal enable and terminal count outputs for multi-stage counting applications
• Provides flexible data loading through independent synchronous and asynchronous preset inputs
• Includes an asynchronous master reset function that forces the counter to its maximum value regardless of other control states

Counter Dividers Applications

• N-divider frequency counters
• Programmable timing circuits
• Digital sequence generation systems

Counter Dividers Procurement Notes

Verify the specific suffix M96 against official datasheets to confirm tape-and-reel packaging specifications. Ensure compatibility with standard SOIC-16 footprints during PCB layout. Confirm RoHS compliance status directly with manufacturer documentation prior to final procurement decisions.

Counter Dividers Selection Notes

Select this component when an 8-bit down-counting capability is required within wide voltage operational limits. The HC series offers high-speed performance suitable for general-purpose digital logic. Consider the availability of both synchronous and asynchronous control inputs for complex state management requirements in embedded designs.

Counter Dividers Part Context

This integrated circuit belongs to the Texas Instruments CD74HC40103 series, representing high-speed CMOS logic technology. It serves as a direct successor or equivalent to legacy 74HC40103 devices, maintaining pinout compatibility while offering modern manufacturing standards and enhanced environmental compliance for contemporary electronic assemblies.

Counter Dividers FAQ

How does the asynchronous preset differ from the synchronous preset?

The asynchronous preset loads data immediately upon activation, ignoring clock signals, whereas the synchronous preset requires a positive clock edge to load data into the counter.

What is the function of the Terminal Enable (TE) input?

The TE input inhibits counting when held high. When low, it allows normal counting and activates the Terminal Count output when the counter reaches zero.
