SN74LS93NS

Counter Dividers Overview

The SN74LS93NS is a 4-bit binary counter integrated circuit manufactured by Texas Instruments. It operates within the LS logic series and features asynchronous reset functionality with negative-edge triggered flip-flops. The device supports an operating supply voltage range of 4.75 V to 5.25 V and functions at temperatures between 0°C and 70°C. It is housed in a 14-SOIC package (0.209 inch width) for surface mount installation.

Counter Dividers Feature Summary

• Asynchronous reset capability for immediate output clearing
• Negative-edge triggered counting mechanism
• Surface mount packaging for automated assembly

Counter Dividers Applications

• Digital frequency division circuits
• Binary counting sequences
• Timing control logic

Counter Dividers Procurement Notes

Verify the specific suffix 'NS' corresponds to the 14-SOIC surface mount package rather than the standard PDIP through-hole variant. Confirm the manufacturer is Texas Instruments, as other vendors produce compatible LS-series counters. Ensure the component meets the required industrial temperature range specifications for the intended application environment.

Counter Dividers Selection Notes

Select this component when a surface mount solution is required for 4-bit binary counting applications. The LS series offers a balance of speed and power consumption suitable for general-purpose digital logic. Verify that the 14-pin SOIC footprint aligns with the PCB layout constraints and that the 5V logic level compatibility matches the system design requirements.

Counter Dividers Part Context

This part belongs to the Texas Instruments SN74LS family of logic devices. It serves as a surface mount alternative to the through-hole SN74LS93N. The device provides basic binary counting capabilities using standard TTL-compatible inputs and outputs, making it suitable for integration into larger digital systems requiring sequential logic operations.
