SN74HC590ADT

Counter Dividers Overview

The SN74HC590ADT is an 8-bit binary counter integrated circuit manufactured by Texas Instruments. It belongs to the HC logic series and features a synchronous up-counting mechanism with positive-edge triggering. The device includes an 8-bit parallel output register equipped with three-state outputs for bus-driven applications. It operates within a supply voltage range of 2 V to 6 V and supports an asynchronous reset function. The component is housed in a 16-SOIC surface-mount package and is rated for operation between -40°C and +85°C.

Counter Dividers Feature Summary

• Synchronous 8-bit binary counting with positive-edge clock triggering
• Parallel output register with three-state outputs for efficient bus interfacing
• Asynchronous reset capability for immediate state clearing
• Wide operating voltage range supporting 2 V to 6 V supply rails

Counter Dividers Applications

• Digital counting systems requiring precise event tracking
• Bus-driven data storage applications utilizing three-state outputs
• Timing and sequencing circuits in industrial control environments
• Frequency division networks in communication equipment

Counter Dividers Procurement Notes

Verify the specific suffix 'DT' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as manufacturing practices may evolve. Check for end-of-life notices or production change notifications from Texas Instruments prior to finalizing procurement plans to ensure long-term availability.

Counter Dividers Selection Notes

Select this component for designs requiring synchronous counting with registered outputs. The three-state outputs facilitate direct connection to shared data buses without external buffering. Ensure the system voltage falls within the 2 V to 6 V range. Consider the SOIC-16 package dimensions for PCB layout constraints compared to through-hole alternatives.

Counter Dividers Part Context

This part is a member of the SN74HC590A family, which standardizes 8-bit counters across various packaging options. Variants such as SN74HC590ADW and SN74HC590ADR share identical electrical characteristics but differ in reel quantities or minor physical tolerances. The HC series provides CMOS performance with compatibility to standard TTL logic levels.

Counter Dividers Replacement Considerations

SN74HC590ADR is a manufacturer-recommended alternative offering equivalent functionality in a different reel configuration.
