74HCT165PW,118

Shift Registers Overview

The Nexperia 74HCT165PW,118 is an 8-bit parallel-in/serial-out shift register in the 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 operates with a supply voltage range of 4.5 V to 5.5 V and supports asynchronous parallel loading when the PL input is LOW. Data shifts on the LOW-to-HIGH transitions of the clock input (CP) when the clock enable (CE) is LOW. Inputs are overvoltage tolerant to 15 V.

Shift Registers Feature Summary

• Asynchronous 8-bit parallel load capability
• Synchronous serial input operation
• TTL-compatible input levels for the HCT variant
• Overvoltage tolerant inputs up to 15 V

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify the specific ordering suffix '118' corresponds to the TSSOP16 package configuration required for your design. Confirm that the 74HCT series TTL input thresholds align with your system's logic voltage levels rather than standard CMOS requirements. Ensure the operating temperature range meets your environmental specifications before finalizing procurement.

Shift Registers Selection Notes

Select this component when TTL-level compatibility is required for the 74HC165 functionality. The PW suffix indicates a TSSOP16 package suitable for surface-mount assembly. Consider the 74HC165 variant if CMOS input levels are preferred or if a wider supply voltage range down to 2.0 V is necessary for the application.

Shift Registers Part Context

This part belongs to the Nexperia 74HCT165 product line, which is part of the broader 74HC/HCT logic family. It serves as an 8-bit shift register designed for digital signal processing tasks requiring data format conversion. The TSSOP16 package provides a compact solution for space-constrained printed circuit board layouts.

Shift Registers Replacement Considerations

The SN74HCT165PWR from Texas Instruments is documented as a substitute option.
