74HC594BQ-Q100X

Shift Registers Overview

The Nexperia 74HC594BQ-Q100X is an automotive-qualified, 8-bit serial-in/serial or parallel-out shift register with a storage register. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features independent clocks and direct clear inputs for both the shift and storage registers. Data shifts on LOW-to-HIGH transitions of the SHCP input, while transfer to the storage register occurs on STCP transitions. It includes a serial output (Q7S) for cascading and utilizes a DHVQFN16 package.

Shift Registers Feature Summary

• Automotive product qualification in accordance with AEC-Q100 Grade 1
• Shift and storage registers have independent direct clear and clock inputs
• DHVQFN package with Side-Wettable Flanks enabling Automatic Optical Inspection (AOI)
• Inputs include clamp diodes to interface with voltages exceeding VCC

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify the specific ordering suffix 'X' against the manufacturer's current documentation to confirm packaging details such as reel specifications. Confirm that the DHVQFN16 package variant matches the required footprint dimensions. Ensure the component meets the specified AEC-Q100 Grade 1 requirements for the target automotive application environment.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with separate storage functionality is required for automotive systems. The HC logic family provides CMOS low power dissipation and high noise immunity. Verify compatibility with system voltage levels between 2.0 V and 6.0 V and ensure the operating temperature range covers the intended environmental conditions.

Shift Registers Part Context

This part belongs to the Nexperia 74HC594-Q100 series, which includes variants like the 74HC594PW-Q100J. The BQ suffix specifically denotes the DHVQFN16 package (SOT763-1). This series is designed for applications requiring robust digital logic performance under automotive-grade reliability standards.
