HEF4894BTT/Q100,11

Shift Registers Overview

The HEF4894BTT/Q100,11 is a 12-stage serial shift register with storage latches and open-drain LED driver outputs. It operates on a 3 V to 15 V supply within an ambient temperature range of -40 °C to +125 °C. The device features two serial outputs for cascading and complies with AEC-Q100 Grade 1 standards. It utilizes CMOS technology for low power dissipation and high noise immunity.

Shift Registers Feature Summary

• Automotive qualification in accordance with AEC-Q100 (Grade 1)
• CMOS low power dissipation with high noise immunity
• Fully static operation across wide supply voltage ranges
• ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)

Shift Registers Applications

• Serial-to-parallel data converting LED drivers
• Automotive lighting control systems
• Cascaded shift register configurations

Shift Registers Procurement Notes

Verify the specific ordering suffix matches the required package type, as the HEF4894B-Q100 family includes both SO20 and TSSOP20 variants. Confirm that the component meets the intended automotive grade requirements by checking the official Nexperia product status documentation before finalizing procurement specifications.

Shift Registers Selection Notes

Select this component when a 12-bit shift register with open-drain outputs is required for direct LED driving. Ensure the design accommodates the specified input transition rates and load capacitance limits to maintain signal integrity. Verify that the operating voltage and temperature ranges align with the system's environmental constraints.

Shift Registers Part Context

This part belongs to the HEF4894B-Q100 family of 12-stage shift-and-store registers manufactured by Nexperia. It is designed specifically for automotive applications requiring robust performance under varying electrical conditions.
