SN74AHCT594NSR

Shift Registers Overview

The SN74AHCT594NSR is an octal edge-triggered D-type flip-flop with three-state outputs manufactured by Texas Instruments. It belongs to the SN74AHCT series, utilizing CMOS technology compatible with TTL logic levels. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum propagation delay of 10.6 ns. It features low output drive capabilities of 8 mA for both high and low states. The component is housed in a 20-pin SOIC package and is rated for operation across an extended temperature range from -40°C to +125°C.

Shift Registers Feature Summary

• Octal configuration providing eight independent D-type flip-flops within a single integrated circuit.
• Three-state outputs allow direct connection to bus systems without external buffer drivers.
• Edge-triggered data storage ensures synchronous operation aligned with clock signal transitions.
• CMOS construction enables compatibility with standard TTL input voltage thresholds.

Shift Registers Applications

• Parallel data buffering in digital communication interfaces
• Synchronous state storage within microprocessor-based control systems
• Bus interface circuits requiring tri-state isolation

Shift Registers Procurement Notes

Verify the specific suffix 'NSR' corresponds to the SOIC-20 package and reel packaging format as documented in official Texas Instruments ordering information. Confirm that the AHCT logic family designation matches the required 4.5 V to 5.5 V operating voltage and TTL input compatibility for the target application design.

Shift Registers Selection Notes

Select this component when an octal storage solution with bus-compatible tri-state outputs is required. The AHCT series is appropriate for designs needing CMOS efficiency with TTL-level input interfacing. Ensure the system operates strictly within the specified 4.5 V to 5.5 V power supply constraints to maintain valid logic levels and timing specifications.

Shift Registers Part Context

This part is a member of the Texas Instruments SN74AHCT logic family, which bridges CMOS performance with TTL compatibility. The SN74AHCT594 variant specifically provides octal storage functionality. It serves as a standard industrial-grade logic component for general-purpose digital circuitry requiring reliable data latching and bus driving capabilities.

Shift Registers Replacement Considerations

Compatible substitutes include the SN74AHCT594DR and SN74AHCT594N, provided the pinout and electrical characteristics remain identical. Verify package dimensions and thermal properties before substitution.
