74VHCT595BQ-Q100X

Shift Registers Overview

The Nexperia 74VHCT595BQ-Q100X is an automotive-grade, high-speed Si-gate CMOS device belonging to the VHCT logic family. It functions as an 8-bit serial-in/serial-out or parallel-out shift register equipped with output latches and 3-state outputs. The component operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. It utilizes the DHVQFN16 package (SOT763-1) featuring side-wettable flanks for automatic optical inspection. The device complies with AEC-Q100 Grade 1 standards and JEDEC No. 7A specifications.

Shift Registers Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standards
• TTL-compatible input levels for direct interfacing with TTL logic systems
• All inputs feature Schmitt-trigger action for improved noise immunity
• DHVQFN package design enables Automatic Optical Inspection of solder joints

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify that the specific ordering suffix matches the required tape-and-reel packaging configuration. Confirm the component meets the exact AEC-Q100 Grade 1 reliability requirements mandated by your automotive application. Ensure the DHVQFN16 footprint aligns with your PCB layout constraints and thermal management strategy before finalizing procurement.

Shift Registers Selection Notes

Select this component when TTL-level compatibility is required alongside high-speed performance in automotive environments. The VHCT series bridges the gap between standard HC logic and HCT logic, offering CMOS power efficiency with TTL input thresholds. Consider the DHVQFN package if board space is limited and automated visual inspection of solder joints is a manufacturing requirement.

Shift Registers Part Context

This part belongs to the Nexperia 74VHC/VHCT595-Q100 product family, which includes variants in SO16 and TSSOP16 packages. The 'BQ' designation specifically identifies the DHVQFN16 leadless package variant. All members of this family share identical functional characteristics but differ in physical dimensions and mounting styles.

Shift Registers Replacement Considerations

Direct pin-compatible substitutes include the 74VHCT595D-Q100 (SO16) and 74VHCT595PW-Q100 (TSSOP16). Verify that any replacement maintains the same AEC-Q100 Grade 1 qualification status and DHVQFN16 package geometry if mechanical fitment is critical.
