SN74LS193NS

Counter Dividers Overview

The SN74LS193NS is a synchronous 4-bit up/down binary counter manufactured by Texas Instruments. It operates within the LS logic series and features dual independent clock inputs for up-counting and down-counting operations. The device supports asynchronous parallel data loading via dedicated preset inputs and includes an asynchronous clear function. It is housed in a 16-pin Small Outline Package (SOIC) with a standard 0.300-inch width. The component functions reliably at supply voltages between 4.75 V and 5.25 V, suitable for standard digital logic applications requiring bidirectional counting capabilities.

Counter Dividers Feature Summary

• Synchronous 4-bit bidirectional binary counting architecture

• Integrated asynchronous master reset for system initialization

Counter Dividers Applications

• Digital frequency division circuits
• Programmable timing sequences
• Position control systems
• Event counting modules

Counter Dividers Procurement Notes

Verify the package designation matches the 16-SOIC form factor required for your PCB layout. Confirm that the LS logic family voltage levels align with your system's I/O specifications. Ensure the operating temperature range of 0°C to 70°C meets your environmental constraints. Cross-reference the manufacturer part number against official distributor catalogs to confirm authenticity and current production status before finalizing orders.

Counter Dividers Selection Notes

Select this component when synchronous operation with separate up/down clocks is necessary. The LS series offers moderate speed suitable for general-purpose digital designs. Consider the SOIC package for surface-mount assembly requirements. Verify compatibility with existing 5V logic families in the signal chain. Evaluate power consumption characteristics relative to other logic families if energy efficiency is a primary design constraint.

Counter Dividers Part Context

This component belongs to the Texas Instruments 74LS193 family of synchronous counters. It serves as a fundamental building block for digital state machines and timing generators. The LS variant provides a balance of speed and power dissipation compared to standard TTL or high-speed CMOS alternatives. It is widely used in educational kits and industrial control panels where reliable binary counting is essential.
