SN74LS293DR

Counter Dividers Overview

The SN74LS293DR is a binary counter integrated circuit manufactured by Texas Instruments, belonging to the LS logic series. It features a 4-bit up-counting architecture and operates within a supply voltage range of 4.75 V to 5.25 V. The device supports a minimum operating temperature of 0°C and a maximum of +70°C. It is housed in a 14-pin SOIC surface-mount package and utilizes asynchronous negative edge triggering for its clock inputs.

Counter Dividers Feature Summary

• Asynchronous 4-bit binary counting capability with dedicated clock inputs
• Compatible with standard TTL and CMOS logic families
• Surface-mount packaging designed for automated PCB assembly

Counter Dividers Applications

• Digital frequency division circuits
• Binary sequence generation systems
• Event counting applications

Counter Dividers Procurement Notes

Verify the specific suffix 'DR' confirms the tape-and-reel packaging format required for your manufacturing line. Confirm that the LS logic family specifications align with your system's voltage and speed requirements. Ensure the 14-pin SOIC footprint matches your board design constraints before finalizing procurement orders.

Counter Dividers Selection Notes

Select this component when a compact surface-mount solution for 4-bit binary counting is required. It serves as an alternative to through-hole DIP variants like the SN74LS293N. Consider the LS series propagation delays and power consumption characteristics relative to other logic families available from Texas Instruments.

Counter Dividers Part Context

This part belongs to the SN74LS293 family of decade and 4-bit binary counters. It shares functional similarities with the SN74LS293D but differs in packaging. The DR suffix specifically denotes the reel-based packaging used for high-volume surface-mount production processes.

Counter Dividers Replacement Considerations

The SN74LS293D is a direct pin-compatible substitute offering identical functionality in a tube package. Other LS-series binary counters may require logic level adjustments or pin reconfiguration.
