74HCT4094DB-Q100J

Shift Registers Overview

The Nexperia 74HCT4094DB-Q100J 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 4.5 V to 5.5 V, utilizing TTL input levels. The device features separate clocks for the shift and storage registers, enabling independent data shifting and latching operations. It includes serial outputs (QS1 and QS2) for cascading capabilities. Qualified to AEC-Q100 Grade 1 standards, it supports ambient temperatures from -40 °C to +125 °C and complies with JEDEC JESD7A specifications.

Shift Registers Feature Summary

• Automotive product qualification in accordance with AEC-Q100 (Grade 1)
• Separate clock inputs for shift and storage registers
• Serial outputs enable cascading for extended bit depth
• High noise immunity with ESD protection exceeding 2000 V HBM

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify the specific suffix 'J' against the official datasheet, as revision history indicates package type changes. Confirm current production status directly with Nexperia, as older SSOP variants have been superseded by SO16 packages. Ensure design compliance with AEC-Q100 requirements for automotive deployment. Cross-reference pinout details for the SOT109-1 package to avoid integration errors.

Shift Registers Selection Notes

Select this component when TTL logic compatibility is required within automotive environments. The 74HCT variant ensures interface compatibility with standard TTL devices while offering low-power dissipation characteristics. Verify that the operating temperature range meets the specific environmental constraints of the target application. Consider the 3-state output capability if bus sharing is necessary in the system architecture.

Shift Registers Part Context

This part belongs to the Nexperia 74HCT4094-Q100 family, which includes HC and HCT variants. The family provides 8-stage shift-and-store bus register functionality. The Q100 designation signifies automotive qualification. The DB suffix typically denotes the SO16 plastic small outline package (SOT109-1), replacing previous SSOP versions in newer revisions.

Shift Registers Replacement Considerations

Check for direct equivalents such as the 74HC4094D-Q100 if CMOS input levels are acceptable instead of TTL. Verify package compatibility between SO16 and alternative footprints. Ensure any substitute maintains AEC-Q100 Grade 1 qualification if automotive reliability is mandatory.
