74HCT165PW-Q100,11

Shift Registers Overview

The Nexperia 74HCT165PW-Q100,11 is an 8-bit parallel-in/serial-out shift register from the 74HCT logic family. It operates with a supply voltage range of 4.5 V to 5.5 V and features eight parallel data inputs (D0-D7), a serial data input (DS), and complementary serial outputs (Q7 and Q7). The device utilizes a TSSOP-16 package (SOT403-1) and supports asynchronous parallel loading when the PL input is LOW. It includes a clock enable (CE) input for synchronous shifting on LOW-to-HIGH CP transitions. Qualified to AEC-Q100 Grade 1 standards, it functions reliably across ambient temperatures from -40 °C to +125 °C.

Shift Registers Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standard
• Asynchronous 8-bit parallel load capability via active LOW PL input
• Overvoltage tolerant inputs up to 15 V for level shifting applications
• ESD protection exceeding 2000 V per Human Body Model

Shift Registers Applications

• Parallel-to-serial data conversion
• Register once, drag and drop operations
• HIGH-to-LOW level shifting applications

Shift Registers Procurement Notes

Verify that the ordering suffix matches the required package type and temperature grade. Confirm the specific variant corresponds to the HCT logic family requirements for TTL-compatible input levels. Ensure the component meets the AEC-Q100 Grade 1 automotive qualification criteria necessary for your intended deployment environment before finalizing procurement.

Shift Registers Selection Notes

Select this component when TTL-level interface compatibility is required within the automotive sector. The 74HCT variant ensures proper logic threshold matching for systems driven by TTL sources. Consider the TSSOP-16 package dimensions for PCB layout constraints. Verify that the operating voltage range aligns with the system's 5 V power supply specifications.

Shift Registers Part Context

This part belongs to the 74HCT165-Q100 series, which are 8-bit parallel-in/serial-out shift registers designed for automotive use. The PW suffix indicates the TSSOP-16 plastic thin shrink small outline package. The Q100 designation confirms compliance with AEC-Q100 standards for automotive electronic components, ensuring reliability under specified thermal and electrical stress conditions.

Shift Registers Replacement Considerations

Direct replacements include other 74HCT165 variants in TSSOP-16 packages such as the 74HCT165PW from different manufacturers, provided they meet AEC-Q100 Grade 1 requirements. Verify pinout compatibility and electrical characteristics against the original datasheet specifications.
