74HC4094DB-Q100J

Shift Registers Overview

The Nexperia 74HC4094DB-Q100J is an automotive-qualified, 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 2.0 V to 6.0 V for the HC variant and 4.5 V to 5.5 V for the HCT variant. The device features separate clocks for the shift and storage registers, enabling independent data shifting and latching operations. It includes two serial outputs (QS1 and QS2) to facilitate cascading across different clock edge speeds. The component is housed in a SO16 plastic small outline package (SOT109-1) and complies with JEDEC standard JESD7A.

Shift Registers Feature Summary

• Automotive product 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
• High electrostatic discharge protection exceeding specified JEDEC class limits

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 datasheet indicates revisions may remove certain package variants like SSOP16. Confirm the logic family (HC vs HCT) aligns with input level requirements. Ensure the component status is checked against the latest Nexperia longevity program updates to confirm production availability before finalizing procurement plans.

Shift Registers Selection Notes

Select this component when an 8-bit shift-and-store bus register with automotive reliability is required. The HC version supports wider voltage ranges suitable for mixed-voltage environments, while the HCT version provides TTL-compatible input levels. Consider the separate clock functionality if independent control over data shifting and storage latching is necessary for the system timing architecture.

Shift Registers Part Context

This part belongs to the Nexperia 74HC4094-Q100 and 74HCT4094-Q100 series of 8-stage shift-and-store bus registers. These devices are designed for automotive applications requiring robust performance under varying temperature conditions from -40 °C to +125 °C. The series ensures compatibility with standard CMOS logic families while providing enhanced durability through AEC-Q100 qualification.

Shift Registers Replacement Considerations

The datasheet revision history notes that the 74HC4094DB-Q100 (SSOP16/SOT338-1) variant was removed in version 3. Verify current availability of the SO16 package. No direct substitute part numbers are listed in the provided documentation.
