CD74HC191M96

Counter Dividers Overview

The CD74HC191M96 is a synchronous 4-bit binary up/down counter manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports a maximum counting rate of 35 MHz. The device features asynchronous reset and preset capabilities, triggered on the positive edge of the clock signal. It is housed in a 16-SOIC surface-mount package with an operating temperature range from -55°C to 125°C.

Counter Dividers Feature Summary

• Synchronous 4-bit binary up/down counting functionality
• Asynchronous reset and parallel load inputs
• High-speed operation with 35 MHz counting rate
• Wide supply voltage compatibility from 2 V to 6 V

Counter Dividers Applications

• Digital frequency division circuits
• Time-base generation for digital clocks
• Position control systems requiring bidirectional counting
• Event counting in industrial automation

Counter Dividers Procurement Notes

Verify the specific suffix M96 corresponds to the tape-and-reel packaging configuration when ordering. Confirm RoHS3 compliance status as required by project specifications. Ensure the 16-SOIC footprint matches the PCB design constraints. Check for any recent product change notices regarding pinout or electrical characteristics before finalizing the bill of materials.

Counter Dividers Selection Notes

Select this component for applications requiring bidirectional synchronous counting with wide voltage flexibility. The HC logic family ensures compatibility with standard CMOS interfaces. Consider the 35 MHz speed limit for high-frequency timing requirements. The extended temperature range makes it suitable for harsh industrial environments where standard commercial grade parts may fail.

Counter Dividers Part Context

This part belongs to the Texas Instruments CD74HC series of high-speed CMOS logic devices. The 74HC191 is a widely used standard logic counter. The M96 suffix typically denotes specific packaging and handling options provided by the manufacturer for automated assembly processes.

Counter Dividers Replacement Considerations

CD74HC191M is the tube-packaged equivalent. CD74HC191N is the DIP alternative. Verify pin compatibility and electrical parameters before substituting.
