74HCT4094D-Q100J

Shift Registers Overview

The Nexperia 74HCT4094D-Q100J is an automotive-grade, 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 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features separate clocks for the shift and storage registers, enabling independent data handling. It includes two serial outputs (QS1 and QS2) for cascading applications and input clamp diodes to facilitate interfacing with voltages exceeding VCC.

Shift Registers Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standards
• Separate clock inputs for shift and storage registers
• Dual serial outputs (QS1 and QS2) for flexible cascading
• Input clamp diodes for high-voltage interface compatibility

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the Q100 series is available in both SO16 and TSSOP16 configurations. Confirm the temperature grade aligns with system requirements, noting that this specific part number corresponds to the SO16 plastic small outline package variant. Ensure design compliance with AEC-Q100 Grade 1 specifications for intended automotive deployment.

Shift Registers Selection Notes

Select this component when TTL-compatible logic levels are required for the HCT series functionality within an automotive environment. The 74HCT4094D-Q100J provides robust ESD protection exceeding 2000 V via HBM and 1000 V via CDM. It is suitable for designs requiring low-power dissipation and reliable operation across the extended industrial temperature range up to +125 °C.

Shift Registers Part Context

This device belongs to the Nexperia 74HC/HCT4094-Q100 family of 8-stage shift-and-store bus registers. It is designed specifically for automotive electronics applications, meeting rigorous reliability standards. The product complements other automotive logic ICs by providing serial-to-parallel conversion capabilities with high noise immunity and standardized pinouts for easy integration into existing automotive circuit architectures.

Shift Registers Replacement Considerations

Direct functional equivalents include the standard commercial versions 74HCT4094D and 74HCT4094PW. For automotive replacements, verify if the HC variant (74HC4094-Q100) meets the CMOS input level requirements instead of the specified TTL levels.
