74AHCT594BQ-Q100,1

Shift Registers Overview

The Nexperia 74AHCT594BQ-Q100,1 is an automotive-qualified, high-speed Si-gate CMOS 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 features Schmitt-trigger inputs for high noise immunity. The device includes independent clocks (SHCP and STCP) and direct overriding clears (SHR and STR) for both the shift and storage registers. It utilizes a DHVQFN-16 package (SOT763-1) with side-wettable flanks.

Shift Registers Feature Summary

• Automotive product qualification in accordance with AEC-Q100 Grade 1
• Independent clocks and direct overriding clears on shift and storage registers
• Overvoltage tolerant inputs up to 5.5 V
• DHVQFN package with Side-Wettable Flanks enabling Automatic Optical Inspection

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify that the ordering suffix ',1' corresponds to the specific reel packaging configuration required by your manufacturing line. Confirm the DHVQFN-16 (SOT763-1) package dimensions align with your PCB footprint design rules. Ensure the component meets the specific temperature range requirements for your intended operational environment.

Shift Registers Selection Notes

Select this part when an 8-bit shift register with separate storage capabilities is required for automotive environments. The AHCT logic level ensures compatibility with TTL input signals while maintaining CMOS performance. Verify that the DHVQFN package style suits your automated assembly process, particularly regarding the side-wettable flank soldering requirements.

Shift Registers Part Context

This component belongs to the Nexperia 74AHC/AHCT594-Q100 family of 8-bit shift registers with output registers. It shares functional similarities with other members of the series but is distinguished by its specific BQ package variant and AHCT logic input levels. The family is designed for high-speed applications requiring robust automotive reliability standards.

Shift Registers Replacement Considerations

Direct substitutes include the 74AHCT594PW-Q100,1 (TSSOP16 package) and the 74AHCT594D-Q100 (SO16 package). These alternatives offer identical electrical functionality but require different PCB footprints due to package variations.
