74AHC594BQ-Q100,11

Shift Registers Overview

The Nexperia 74AHC594BQ-Q100,11 is an automotive-grade 8-bit serial-in, parallel-out shift register with an output storage register. It operates within a supply voltage range of 2.0 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device utilizes positive-edge triggered clocks for both the shift and storage registers, featuring independent direct overriding clears. It is housed in a DHVQFN16 package (SOT763-1) and complies with AEC-Q100 Grade 1 standards.

Shift Registers Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 specifications
• High noise immunity with Schmitt-trigger action on all inputs
• Overvoltage tolerant inputs capable of handling up to 5.5 V
• DHVQFN package design enabling 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 DHVQFN16 package configuration. Confirm the component meets AEC-Q100 Grade 1 requirements for the target automotive environment. Ensure input logic levels align with the 74AHC family specifications rather than TTL levels. Validate thermal dissipation limits against the specific PCB layout constraints.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with separate storage functionality is required for automotive systems. The DHVQFN16 package offers a compact footprint suitable for space-constrained designs. Verify compatibility with the system's operating voltage range between 2.0 V and 5.5 V. Consider the high noise immunity and overvoltage tolerance for robust signal integrity in electrically noisy environments.

Shift Registers Part Context

This part belongs to the Nexperia 74AHC594-Q100 series, which includes pin-compatible variants such as the 74AHCT594-Q100. The series represents high-speed Si-gate CMOS technology compatible with Low-Power Schottky TTL. Other package options for this logical function include SO16 and TSSOP16, providing flexibility for different manufacturing and assembly requirements.

Shift Registers Replacement Considerations

The 74AHCT594BQ-Q100 serves as a functional substitute within the same family, differing primarily in input logic level compatibility.
