CD74AC193M

Counter Dividers Overview

The CD74AC193M is a synchronous 4-bit binary up/down counter manufactured by Harris Corporation. It features independent clock inputs for counting up and down, along with an asynchronous clear input. The device operates within a supply voltage range of 2V to 6V and supports data rates up to 50MHz. It is housed in a 16-pin SOIC package and functions across an industrial temperature range of -55°C to 125°C.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting capability with separate up and down clock inputs
• Asynchronous master reset function for immediate initialization
• High-speed operation supporting frequencies up to 50MHz
• Wide operating voltage range from 2V to 6V

Counter Dividers Applications

• Frequency division circuits
• Digital timing sequences
• Counting applications in industrial control systems

Counter Dividers Procurement Notes

Verify the manufacturer origin, as Harris Corporation assets were acquired by L3Harris Technologies. Confirm the specific suffix 'M' corresponds to the 16-SOIC package variant. Check RoHS compliance status, as older Harris CMOS logic may not meet current environmental standards. Ensure the component matches the AC series specifications rather than HC or HCT variants.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit bidirectional counter is required with high-speed performance. The AC series offers faster propagation delays compared to standard HC logic. Verify that the 16-SOIC package fits the PCB layout constraints. Consider the 2V-6V supply range compatibility with the system's power rails before integration.

Counter Dividers Part Context

This part belongs to the 74AC family of high-speed CMOS logic devices originally produced by Harris Semiconductor. The CD74AC193 specifically implements a presettable synchronous 4-bit binary up/down counter architecture. Following corporate restructuring, these products are now managed under L3Harris Technologies, Inc., maintaining the original functional specifications.

Counter Dividers Replacement Considerations

Compatible substitutes include the SN74AC193 from Texas Instruments and the MC74AC193 from ON Semiconductor. Ensure the replacement maintains the 16-SOIC package and AC series speed grades.
