SN74LS93N

Counter Dividers Overview

The SN74LS93N is a synchronous 4-bit binary counter integrated circuit manufactured by Texas Instruments. It operates within the standard TTL logic family and requires a supply voltage ranging from 4.75 V to 5.25 V. The device features asynchronous reset functionality and utilizes negative-edge triggering for clock inputs. Designed for through-hole mounting, it is housed in a standard 14-pin PDIP package. The component supports a maximum counting rate of 42 MHz and functions reliably across an operating temperature range of 0°C to +70°C.

Counter Dividers Feature Summary

• Provides four independent binary counting stages with ripple output capabilities
• Includes dedicated asynchronous reset inputs for immediate state clearing
• Utilizes negative-edge triggered clocking for precise timing synchronization

Counter Dividers Applications

• Digital frequency division circuits
• Binary sequence generation systems
• Timing control modules in industrial equipment

Counter Dividers Procurement Notes

Verify that the specific part number matches the required PDIP-14 through-hole package configuration. Confirm the logic family designation corresponds to Low-power Schottky (LS) specifications to ensure compatibility with existing system voltage levels. Check manufacturing date codes against project lifecycle requirements to avoid obsolescence risks during long-term deployment phases.

Counter Dividers Selection Notes

Select this component when a simple, robust binary counter is needed for low-speed digital applications. It serves as a suitable alternative to more complex programmable counters where fixed binary division ratios are sufficient. Consider the power dissipation characteristics inherent to the LS series compared to modern CMOS alternatives if energy efficiency is a primary design constraint.

Counter Dividers Part Context

This component belongs to the widely adopted SN74xx series of digital logic integrated circuits. It represents a standard solution for basic counting operations in legacy and current industrial designs. The SN74LS93N is frequently used in conjunction with other TTL logic gates to create complex sequential circuits without requiring microprocessors.

Counter Dividers Replacement Considerations

The SN74LS93NS variant offers identical logical functionality but utilizes a surface-mount SOIC package instead of the through-hole DIP format.
