Counter Dividers Procurement Notes

Verify the specific suffix E4 against official manufacturer documentation to confirm RoHS compliance and lead-free status. Confirm that the SOIC-16 package dimensions match your PCB footprint requirements. Ensure the supply voltage provided aligns with the 2 V to 6 V operational range specified in the datasheet. Check for any recent product change notifications regarding pinout or electrical characteristics updates.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit counter with independent load and reset controls is required. The HC series offers faster switching speeds compared to standard 74LS counterparts while maintaining compatible logic levels. Consider the 16-SOIC package for surface-mount assembly constraints. Verify that the input voltage levels are compatible with the driving logic family used in the system design.

Counter Dividers Part Context

This part belongs to the Texas Instruments CD74HC191 family of high-speed CMOS logic devices. It is functionally equivalent to other industry-standard 4-bit synchronous counters but utilizes TI's specific manufacturing processes. The M96 suffix typically denotes a specific tape-and-reel packaging configuration intended for automated surface-mount assembly lines.
