74HC166PW-Q100J

Shift Registers Overview

The Nexperia 74HC166PW-Q100J is an automotive-qualified, 8-bit parallel-in/serial-out shift register housed in a TSSOP16 (SOT403-1) package. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features eight parallel data inputs (D0–D7), a serial data input (DS), and a serial output (Q7). Control functions include a clock enable (CE), parallel enable (PE), asynchronous master reset (MR), and edge-triggered clock input (CP). Inputs utilize clamp diodes for overvoltage tolerance.

Shift Registers Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• CMOS technology providing low power dissipation and high noise immunity
• Latch-up performance exceeding 100 mA per JESD 78 Class II Level B
• Input levels compatible with CMOS logic standards

Shift Registers Applications

• Synchronous parallel-to-serial data conversion
• Synchronous serial input expansion
• Automotive electronic systems requiring qualified logic components

Shift Registers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature grade. Confirm that the component meets the required AEC-Q100 Grade 1 specifications for your target application environment. Ensure design compatibility with the specified operating voltage and temperature ranges before finalizing procurement.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with synchronous parallel loading is required for automotive environments. Verify that the system voltage falls within the 2.0 V to 6.0 V range. Consider the TSSOP16 package dimensions if board space is constrained. Ensure interface logic levels match the CMOS input requirements defined in the datasheet.

Shift Registers Part Context

This part belongs to the Nexperia 74HC166-Q100 family of 8-bit shift registers. It shares functional similarities with the 74HCT166-Q100 variant, which utilizes TTL input levels instead of CMOS. Both variants are designed for automotive applications and offer identical pin configurations and core shifting capabilities within their respective logic families.

Shift Registers Replacement Considerations

The 74HC166D-Q100 serves as a direct functional replacement using an SO16 package. Designers must account for differences in thermal derating and physical footprint when substituting between TSSOP16 and SO16 packages.
