74HCT166D-Q100J

Shift Registers Overview

The Nexperia 74HCT166D-Q100J is an 8-bit parallel-in/serial-out shift register qualified to AEC-Q100 Grade 1 standards for automotive applications. It operates within a supply voltage range of 4.5 V to 5.5 V and supports temperatures from -40 °C to +125 °C. The device features TTL-compatible input levels, asynchronous master reset (MR), clock enable (CE), and parallel enable (PE) controls. Packaged in SO16 (SOT109-1), it provides serial data output at Q7 with propagation delays up to 60 ns.

Shift Registers Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 specifications
• TTL-compatible input levels for direct interfacing with logic systems
• Asynchronous master reset and clock enable functionality for precise control

Shift Registers Applications

• Automotive electronic systems requiring robust logic shifting
• Synchronous parallel-to-serial data conversion tasks
• Expansion of serial input capabilities in digital circuits

Shift Registers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and temperature grade. Confirm that the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability. Check for any recent product change notices or lifecycle status updates before finalizing orders.

Shift Registers Selection Notes

Select this component when TTL-level compatibility is required alongside automotive reliability standards. Ensure the application environment stays within the specified -40 °C to +125 °C operating range. Verify that the SO16 package dimensions fit the available PCB footprint constraints and that the power dissipation limits are respected under maximum load conditions.

Shift Registers Part Context

This part belongs to the Nexperia 74HCT166-Q100 family of 8-bit shift registers designed for high-reliability environments. It shares functional similarities with other automotive-grade logic devices but is distinct due to its specific HCT input characteristics and parallel-load capability. The series is engineered to meet stringent automotive quality requirements while maintaining standard logic interface compatibility.

Shift Registers Replacement Considerations

Direct substitutes include the 74HC166D-Q100J for HC-level input compatibility. Cross-reference pinouts and electrical characteristics carefully when replacing with non-Nexperia equivalents to ensure functional parity in automotive contexts.
