74HCT165BQ,115

Shift Registers Overview

The Nexperia 74HCT165BQ,115 is an 8-bit parallel-in/serial-out shift register housed in a DHVQFN16 package (SOT763-1). It operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features asynchronous parallel loading via an active LOW PL input and synchronous serial shifting triggered by LOW-to-HIGH transitions on the CP clock input when CE is LOW. Inputs are overvoltage tolerant up to 15 V.

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 providing both true and inverted signals
• Input levels compatible with TTL logic standards

Shift Registers Applications

• Parallel-to-serial data conversion
• HIGH-to-LOW level shifting applications
• Expansion of digital input ports in control systems

Shift Registers Procurement Notes

Verify that the ordering suffix ,115 corresponds specifically to the DHVQFN16 package configuration. Confirm the manufacturer designation matches Nexperia USA Inc. Ensure the component meets the required temperature range specifications for the intended operating environment before finalizing procurement orders.

Shift Registers Selection Notes

Select this component when TTL-compatible logic levels are required for the 74HCT series. The DHVQFN16 package offers space-saving benefits for PCB layouts. Ensure the application utilizes the specified 4.5 V to 5.5 V supply voltage range to maintain proper signal integrity and performance characteristics.

Shift Registers Part Context

This part belongs to the 74HCT165 family of 8-bit shift registers manufactured by Nexperia. It shares functional compatibility with other variants in the series but differs in packaging. The BQ suffix indicates the specific DHVQFN16 leadless thermal enhanced quad flat package format used for surface mount assembly.

Shift Registers Replacement Considerations

SN74HCT165PWR by Texas Instruments is documented as a substitute option.
