HEF4094BT-Q100J

Shift Registers Overview

The HEF4094BT-Q100 is an 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs. It operates within a supply voltage range of 3.0 V to 15.0 V. The device features separate clocks for the shift and storage registers, along with two serial outputs (QS1 and QS2) for cascading. It is qualified to AEC-Q100 Grade 1 standards and specified for ambient temperatures from -40 °C to +125 °C.

Shift Registers Feature Summary

• Automotive product qualification in accordance with AEC-Q100 (Grade 1)
• Fully static operation with CMOS low power dissipation
• High noise immunity and standardized symmetrical output characteristics
• ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)

Shift Registers Applications

• Serial-to-parallel data conversion
• Remote control holding register
• Digitally controlled equipment

Shift Registers Procurement Notes

Verify the specific package variant against project requirements, as the HEF4094B-Q100 family includes both SO16 (SOT109-1) and TSSOP16 (SOT403-1) options. Confirm that the selected component meets the required temperature grade and automotive qualification standards before finalizing procurement specifications.

Shift Registers Selection Notes

Select this component when an 8-stage shift-and-store register with 3-state outputs is required for automotive or industrial applications. Ensure the design accommodates the wide supply voltage range and verify that the operating temperature falls within the specified -40 °C to +125 °C range for reliable performance.

Shift Registers Part Context

This part belongs to the HEF4094B-Q100 series, which are 8-stage shift-and-store registers designed for robust digital logic applications. The series is characterized by its compliance with automotive standards and its ability to interface directly with common bus lines through buffered 3-state outputs.
