HEF4094BTT-Q100J

Shift Registers Overview

The HEF4094BTT-Q100J is an automotive-qualified 8-stage serial shift-and-store register manufactured by Nexperia. It features a storage latch for strobing data from the serial input to parallel buffered 3-state outputs (QP0–QP7). The device operates within a recommended supply voltage range of 3.0 V to 15.0 V and supports fully static operation. Data shifts on positive-going clock transitions, with transfer to the storage register occurring when the strobe input is HIGH. Outputs assume a high-impedance OFF-state when the output enable signal is LOW. The component is housed in a TSSOP16 package (SOT403-1) and complies with AEC-Q100 Grade 1 standards.

Shift Registers Feature Summary

• Automotive product qualification in accordance with AEC-Q100 (Grade 1)
• Wide supply voltage range from 3.0 V to 15.0 V
• ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)
• CMOS low power dissipation with high noise immunity

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify that the ordering suffix matches the required package type, as the HEF4094B-Q100 family includes both SO16 and TSSOP16 variants. Confirm that the specific application environment falls within the specified temperature ranges of -40 °C to +85 °C or -40 °C to +125 °C. Ensure design safeguards are in place, as the product is not designed for life-support or safety-critical systems without explicit written agreement.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with separate shift and storage clocks is required for automotive applications. The TSSOP16 package is suitable for surface-mount designs needing a thin profile. Consider the dual serial outputs (QS1 and QS2) if cascading multiple devices with varying clock rise times. Verify that the 3-state outputs meet the bus line connection requirements of the target system.

Shift Registers Part Context

The HEF4094BTT-Q100J belongs to the HEF4094B-Q100 series of 8-stage shift-and-store registers. This series is part of Nexperia's portfolio of logic ICs qualified for automotive use under AEC-Q100 standards. The 'TT' in the model number specifically denotes the TSSOP16 plastic thin shrink small outline package (SOT403-1), distinguishing it from the SO16 variant.

Shift Registers FAQ

How does the device handle cascading with different clock speeds?

The device provides two serial outputs: QS1 outputs data on the positive-going clock edge for fast clock rise times, while QS2 outputs data on the next negative-going clock edge for slow clock rise times.

What is the function of the Output Enable (OE) input?

A HIGH level on the OE input allows data in the storage register to appear at the outputs. A LOW level causes the outputs to assume a high-impedance OFF-state without affecting the internal state of the registers.
