74HCT165D,652

Shift Registers Overview

The Nexperia 74HCT165D,652 is an 8-bit parallel-in/serial-out shift register belonging to the HCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features asynchronous parallel loading via an active LOW PL input. The device provides complementary serial outputs (Q7 and Q7) and accepts serial data at DS. Inputs are overvoltage tolerant up to 15 V, enabling HIGH-to-LOW level shifting applications. It utilizes a 16-lead SO plastic small outline package (SOT109-1).

Shift Registers Feature Summary

• Asynchronous 8-bit parallel load capability for immediate data capture.
• Serial data shifting controlled by clock enable and clock pulse inputs.
• Complementary serial outputs provide both true and inverted signals.
• Input levels compatible with TTL standards for direct interfacing.

Shift Registers Applications

• Parallel-to-serial data conversion in communication systems.
• Expansion of digital I/O ports using minimal control lines.
• HIGH-to-LOW level shifting applications due to overvoltage tolerant inputs.

Shift Registers Procurement Notes

Verify the specific ordering suffix ',652' against current Nexperia documentation to confirm the exact tape-and-reel packaging configuration and manufacturing site. Ensure the component status is confirmed as active production rather than obsolete or limited stock before finalizing procurement plans.

Shift Registers Selection Notes

Select this component when TTL-compatible logic levels are required for the 74HCT series. It is suitable for designs needing asynchronous parallel loading and serial output capabilities. Verify that the operating temperature range and power dissipation limits align with the system's thermal constraints and environmental conditions.

Shift Registers Part Context

This part belongs to the 74HCT165 family of 8-bit shift registers manufactured by Nexperia USA Inc. It shares functional characteristics with the 74HC165 but is optimized for CMOS operation with TTL-compatible input levels. The 'D' designation indicates the SO16 surface-mount package type.
