SN74LS193N

Counter Dividers Overview

The SN74LS193N is a synchronous 4-bit up/down binary counter manufactured by Texas Instruments, not onsemi. It features dual clock inputs for independent up and down counting operations. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports asynchronous reset functionality. It is housed in a 16-PDIP package with through-hole mounting capabilities. The component is designed for industrial temperature ranges from 0°C to +70°C.

Counter Dividers Feature Summary

• Synchronous 4-bit bidirectional binary counting capability
• Independent clock inputs for up and down count directions
• Asynchronous clear input for immediate reset

Counter Dividers Applications

• Digital frequency division circuits
• Time base generators for digital clocks
• Position control systems requiring bidirectional counting

Counter Dividers Procurement Notes

Verify the manufacturer designation carefully, as the SN74LS193N part number is primarily associated with Texas Instruments. Confirm that the specific batch or variant matches the required logic family specifications and pinout compatibility before integration into designs originally intended for other manufacturers' versions of this component.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit counter with separate up/down controls is required. Ensure the design accommodates the LS TTL logic levels and power supply requirements. Consider the PDIP-16 package constraints for PCB layout and thermal management in high-density applications.

Counter Dividers Part Context

The SN74LS193 belongs to the standard 74LS series of logic integrated circuits. It serves as a fundamental building block for sequential logic designs requiring precise binary counting operations. The device is widely recognized for its reliability in general-purpose digital systems and educational electronics projects.

Counter Dividers FAQ

Does the SN74LS193N support simultaneous up and down counting?

No, it uses separate clock inputs for up and down operations, allowing only one direction at a time.

What is the function of the asynchronous clear input?

The asynchronous clear input immediately resets all four flip-flops to zero regardless of the clock state.
