SN74LS193DR

Counter Dividers Overview

The SN74LS193DR is a synchronous 4-bit up/down binary counter manufactured by Texas Instruments. It operates within the LS logic series and features dual clock inputs for independent up and down counting operations. The device includes an asynchronous clear input for immediate reset functionality. It is housed in a 16-SOIC surface-mount package with a standard supply voltage range of 4.75 V to 5.25 V. The component supports a maximum counting rate of 32 MHz and functions reliably across an operating temperature range of 0°C to +70°C.

Counter Dividers Feature Summary

• Synchronous 4-bit up/down binary counting capability with separate clock inputs
• Asynchronous clear input for immediate reset of all counter stages
• Surface-mount packaging suitable for automated assembly processes

Counter Dividers Applications

• Digital frequency division circuits
• Time-base generation systems
• Binary sequence generation applications

Counter Dividers Procurement Notes

Verify the specific suffix 'DR' indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status as per current manufacturer documentation, noting potential variations in lead-free specifications over time. Ensure the ordering quantity aligns with reel requirements if bulk procurement is intended. Cross-reference the manufacturer part number with distributor codes to avoid substitution errors during acquisition.

Counter Dividers Selection Notes

Select this component for designs requiring synchronous bidirectional counting in a compact surface-mount form factor. The LS logic family offers a balance of speed and power consumption suitable for general-purpose digital applications. Consider the 16-SOIC package dimensions for PCB layout constraints. Verify that the 32 MHz maximum frequency meets the system timing requirements before finalizing the design.

Counter Dividers Part Context

This device belongs to the Texas Instruments SN74LS193 family of synchronous counters. It is functionally compatible with other LS-series logic devices but requires appropriate voltage levels and load conditions. The DR suffix specifically denotes the reel-packaged variant of the SN74LS193D, distinguishing it from tube-packed versions while maintaining identical electrical characteristics and pinout configurations.

Counter Dividers Replacement Considerations

SN74LS193D is the tube-packaged equivalent with identical electrical performance.
