SN74LS193NSR

Counter Dividers Overview

The SN74LS193NSR is a synchronous 4-bit up/down binary counter from the Texas Instruments SN74LS series. It features dual independent clock inputs for separate up and down counting operations, along with an asynchronous clear input. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a maximum count rate of 25 MHz. It is housed in a 16-pin Small Outline Package (SOIC) and functions reliably across an operating temperature range of 0°C to +70°C.

Counter Dividers Feature Summary

• Synchronous 4-bit bidirectional binary counting capability
• Dual independent clock inputs for separate up and down operations
• Asynchronous clear function for immediate reset

Counter Dividers Applications

• Digital frequency division circuits
• Time-base generation systems
• Pulse sequence control logic

Counter Dividers Procurement Notes

Verify the package designation matches the 16-pin SOIC specification. Confirm the suffix indicates tape and reel packaging. Ensure the component meets RoHS compliance requirements. Check that the manufacturer is Texas Instruments. Validate the operating temperature range against application needs.

Counter Dividers Selection Notes

Select this component when synchronous bidirectional counting is required in LS logic environments. It serves as a direct replacement for through-hole DIP versions in surface-mount designs. Consider the 25 MHz speed limit and 5V supply constraint. Verify pin compatibility if substituting other 74LS counters.

Counter Dividers Part Context

This part belongs to the standard 74LS family of logic integrated circuits. It provides a surface-mount alternative to the through-hole SN74LS193N. The device implements standard TTL-compatible logic levels. It is designed for general-purpose digital counting applications requiring reliable performance in industrial temperature ranges.

Counter Dividers Replacement Considerations

SN74LS193DR is a manufacturer-recommended surface-mount substitute.
