HEF4794BT-Q100118

Shift Registers Overview

The HEF4794BT-Q100,118 is an 8-stage serial shift register with storage latches for strobing data from a serial input to parallel open-drain LED driver outputs. It operates on positive-going clock transitions and supports cascading via two serial outputs (QS1 and QS2). The device functions within a recommended supply voltage range of 3 V to 15 V referenced to ground. It is qualified to AEC-Q100 Grade 1 standards and supports ambient temperatures from -40 °C to +125 °C.

Shift Registers Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1
• Wide supply voltage range from 3.0 V to 15.0 V
• High noise immunity and fully static operation
• ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)

Shift Registers Applications

• Automotive lighting systems
• Industrial LED drivers
• Serial-to-parallel data conversion

Shift Registers Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the component meets the intended environmental temperature requirements for the target application. Ensure design compliance with absolute maximum ratings to prevent permanent damage during operation.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with parallel output capability is required for automotive or industrial environments. Consider the open-drain output structure for driving external loads. Evaluate the propagation delay characteristics against the system clock frequency requirements.
