SN74HCS594QBQBRQ1

Shift Registers Overview

The SN74HCS594QBQBRQ1 is an automotive-grade, 8-bit serial-in, parallel-out shift register with a storage register. It operates within a supply voltage range of 2 V to 6 V and supports an ambient temperature range from -40°C to +125°C. The device features Schmitt-trigger inputs for noise rejection and balanced CMOS push-pull outputs capable of ±7.8 mA drive current at 6 V. It is qualified under AEC-Q100 standards and utilizes a 16-pin WBQFN package.

Shift Registers Feature Summary

• AEC-Q100 qualification for automotive environments
• Schmitt-trigger inputs for noisy signal tolerance
• Balanced CMOS push-pull output drivers
• Wettable flank QFN package availability

Shift Registers Applications

• Output expansion
• LED matrix control
• 7-segment display control
• 8-bit data storage

Shift Registers Procurement Notes

Verify the specific ordering suffix matches the required package type, as the SN74HCS594-Q1 family includes multiple options such as TSSOP, SOIC, WQFN, and SOT-23-THN. Confirm that the WBQB designation corresponds to the wettable flank variant if automatic optical inspection compatibility is required. Ensure the component meets the specified AEC-Q100 grade requirements for the target automotive application.

Shift Registers Selection Notes

Select this component when designing systems requiring robust noise immunity due to its Schmitt-trigger input architecture. It is suitable for applications needing simple GPIO control without complex communication interfaces. Consider the wide operating voltage range for flexibility in power supply design. Verify thermal performance requirements against the junction-to-ambient resistance values provided for the specific package selected.

Shift Registers Part Context

This part belongs to the Texas Instruments SN74HCS594-Q1 family of automotive logic devices. It is designed to replace standard logic components in harsh automotive environments. The HCS series combines high-speed CMOS technology with Schmitt-trigger functionality. The device provides a reliable solution for shifting and storing digital data in vehicle electronics and infotainment systems.

Shift Registers Replacement Considerations

Direct substitutes include other SN74HCS594-Q1 variants with different packages, such as SN74HCS594PWQ1 or SN74HCS594DRQ1. Non-automotive equivalents like the SN74HCS594 may be considered if AEC-Q100 qualification is not mandatory.
