74HC165D,653

Shift Registers Overview

The Nexperia 74HC165D,653 is an 8-bit parallel-in/serial-out shift register housed in a 16-lead SO (SOT109-1) plastic small outline package. It operates on a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device features eight parallel data inputs (D0 to D7), a serial data input (DS), clock (CP), clock enable (CE), and active LOW asynchronous parallel load (PL) inputs. Outputs include complementary serial outputs Q7 and Q7.

Shift Registers Feature Summary

• Asynchronous 8-bit parallel loading capability
• Complementary serial output configuration
• Input levels compliant with JEDEC standards

Shift Registers Applications

• Parallel-to-serial data conversion

Shift Registers Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the component status remains current for production use. Ensure environmental compliance requirements align with project specifications before finalizing procurement orders.

Shift Registers Selection Notes

Select this component when an 8-bit parallel-to-serial conversion function is required within a wide voltage operating range. The SO package provides a standard surface-mount footprint suitable for general-purpose logic applications requiring CMOS low power dissipation characteristics.

Shift Registers Part Context

This part belongs to the 74HC165 family of 8-bit parallel-in/serial-out shift registers manufactured by Nexperia USA Inc. It shares functional similarities with other members of the series but is distinguished by its specific 16-lead SO package designation and extended industrial temperature rating capabilities.

Shift Registers FAQ

How does the parallel load input operate?

When the parallel load input (PL) is LOW, data from the parallel inputs D0 to D7 is loaded into the shift register asynchronously.

What is the function of the clock enable input?

A HIGH level on the clock enable (CE) input disables the CP input, inhibiting serial shifting operations.
