74LVC594AD-Q100J

Shift Registers Overview

The Nexperia 74LVC594AD-Q100J is an 8-bit serial-in/serial or parallel-out shift register with a storage register, housed in an SO16 (SOT109-1) package. It operates within a supply voltage range of 1.2 V to 3.6 V and supports input voltages up to 5.5 V. The device features separate clocks for the shift and storage registers, allowing independent control. It includes Schmitt-trigger inputs for noise tolerance and IOFF circuitry for partial power-down protection. Qualified to AEC-Q100 Grade 1 standards, it functions reliably from -40 °C to +125 °C.

Shift Registers Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• IOFF circuitry prevents damaging backflow current during partial power-down
• Schmitt-trigger action on all inputs ensures tolerance to slow rise and fall times
• Overvoltage tolerant inputs allow direct interfacing with 3.3 V and 5 V devices

Shift Registers Applications

• Serial-to-parallel data conversion
• Remote control holding register

Shift Registers Procurement Notes

Verify the specific ordering suffix 'J' against official Nexperia documentation to confirm exact packaging configuration, as standard datasheets may list base part numbers without suffix details. Confirm that the SO16 package variant matches the required PCB footprint. Ensure the automotive grade designation aligns with project reliability requirements before finalizing procurement specifications.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with output storage is required for automotive environments. The wide supply voltage range and overvoltage-tolerant inputs facilitate integration into mixed-voltage systems. The inclusion of separate clock and reset lines provides flexibility in timing control. Verify that the SO16 package dimensions fit the available board space constraints.

Shift Registers Part Context

This device belongs to the Nexperia 74LVC594A-Q100 family of 8-bit shift registers. Other variants in this family include the TSSOP16 (74LVC594APW-Q100) and DHVQFN16 (74LVC594ABQ-Q100) packages. All variants share identical electrical characteristics and functionality, differing only in physical package type and pinout geometry.

Shift Registers Replacement Considerations

Direct replacements include other 74LVC594A-Q100 variants with different packages, such as 74LVC594APW-Q100 or 74LVC594ABQ-Q100, provided the mechanical footprint allows. Cross-brand equivalents must be verified for compatible logic levels, package dimensions, and AEC-Q100 qualification status.
