74HCT165DB,112

Shift Registers Overview

The 74HCT165DB,112 is an 8-bit parallel-in/serial-out shift register from the Nexperia 74HCT logic family. It features a serial data input (DS), eight parallel data inputs (D0 to D7), and two complementary serial outputs (Q7 and Q7). The device supports asynchronous parallel loading when the PL input is LOW and synchronous serial shifting on LOW-to-HIGH clock transitions when CE is LOW. Inputs are overvoltage tolerant to 15 V, enabling HIGH-to-LOW level shifting applications.

Shift Registers Feature Summary

• Asynchronous 8-bit parallel load capability for immediate data capture
• Synchronous serial input with edge-triggered clocking
• Input levels compatible with TTL standards
• Complementary serial outputs for versatile interfacing

Shift Registers Applications

• Parallel-to-serial data conversion
• HIGH-to-LOW level shifting applications
• Digital signal processing interfaces

Shift Registers Procurement Notes

Verify component authenticity through official Nexperia channels or authorized distributors. Confirm package integrity and pin alignment against SOT339-1 specifications. Ensure compliance with RoHS directives and JEDEC standards prior to integration into final designs.

Shift Registers Selection Notes

Select this component for applications requiring TTL-compatible logic levels and robust noise immunity. Verify that the operating voltage range of 4.5 V to 5.5 V aligns with system requirements. Consider the SSOP-16 package constraints for PCB layout and thermal management during design phase.

Shift Registers Part Context
