SN74AHCT594DG4

Shift Registers Overview

The SN74AHCT594DG4 is an 8-bit shift register with output registers manufactured by Texas Instruments. It belongs to the 74AHCT logic family, designed for operation with a 5V supply voltage. The device features serial-to-parallel data conversion capabilities and utilizes a 16-pin SOIC surface-mount package. It supports asynchronous clearing of the storage register and provides registered parallel outputs. The component operates within a temperature range of -40°C to +125°C.

Shift Registers Feature Summary

• Serial-to-parallel data shifting functionality
• Registered parallel outputs
• Asynchronous clear capability for the storage register

Shift Registers Applications

• General-purpose digital data storage
• Parallel output expansion in embedded systems
• Interface bridging between serial controllers and parallel peripherals

Shift Registers Procurement Notes

Verify the exact suffix 'DG4' against current manufacturer documentation, as lead generations may vary. Confirm RoHS compliance status directly with the supplier or official datasheet, as environmental declarations can change. Ensure the SOIC-16 footprint matches your PCB design constraints before finalizing procurement orders.

Shift Registers Selection Notes

Select this component when a 5V logic interface is required for shift register applications. The AHCT series ensures compatibility with standard TTL logic levels while offering CMOS performance characteristics. Consider the 16-SOIC package size for space-constrained surface-mount designs requiring robust thermal performance across wide industrial temperature ranges.

Shift Registers Part Context

This part is a specific variant of the SN74AHCT594 series, distinguished by its green (RoHS-compliant) manufacturing process indicated by the G4 suffix. It falls under Texas Instruments' broad portfolio of high-speed CMOS logic devices, serving as a foundational building block for sequential logic circuits in consumer and industrial electronics.

Shift Registers Replacement Considerations

Direct substitutes include the SN74AHCT594DR and SN74AHCT594D. Cross-brand equivalents from manufacturers like Nexperia or ON Semiconductor should be verified for pinout and electrical parameter compatibility.
