SN74LS393N

Counter Dividers Overview

The SN74LS393N is a dual 4-bit counter integrated circuit from Texas Instruments, housed in a 14-pin PDIP package. It contains two independent counters: one configured as a binary counter and the other as a decade counter. Both counters operate asynchronously with negative-edge triggering and feature asynchronous reset inputs. The device functions within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range of 0°C to +70°C.

Counter Dividers Feature Summary

• Integrates two independent 4-bit counting stages within a single package
• Provides distinct binary and decade counting configurations for flexible design implementation
• Features asynchronous reset capability for immediate output clearing

Counter Dividers Applications

• Digital frequency division circuits
• Binary-coded decimal (BCD) counting systems
• Timing and sequencing logic modules

Counter Dividers Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm pinout compatibility and electrical specifications. Ensure the procurement channel provides valid traceability for the SN74LS393N part number. Confirm RoHS compliance status through the manufacturer's current production data sheets before finalizing acquisition.

Counter Dividers Selection Notes

Select this component when a design requires both binary and decade counting capabilities in a low-power Schottky logic family. The asynchronous nature of the counters suits applications where precise clock synchronization between stages is not critical. Verify that the 14-pin DIP package aligns with the target PCB footprint and assembly requirements.

Counter Dividers Part Context

This component belongs to the Texas Instruments SN74LS series, which utilizes Low Power Schottky technology to balance speed and power consumption. The SN74LS393N serves as a fundamental building block for digital logic designs requiring simple, reliable counting operations without complex synchronous control overhead.

Counter Dividers Replacement Considerations

Compatible substitutes include the SN74LS393DR and SN74LS393NSR. Verify that alternative packages maintain identical pin assignments and electrical characteristics to ensure direct interchangeability in existing designs.
