MC74HC165ADR2G-Q

Shift Registers Overview

The MC74HC165ADR2G-Q is an 8-bit parallel-in/serial-out shift register manufactured by onsemi. It features a high-performance silicon-gate CMOS process and operates within a voltage range of 2.0 to 6.0 V. The device includes eight parallel data inputs (A through H), a serial data input (SA), and complementary serial outputs (QH and QH). It supports asynchronous parallel loading when the Serial Shift/Parallel Load input is low, and serial shifting on the rising edge of the Clock or Clock Inhibit signals.

Shift Registers Feature Summary

• Supports asynchronous parallel data loading and serial shifting via dedicated control inputs
• Features a dual-input NOR clock structure allowing independent clock sources or clock inhibition
• Provides complementary non-inverted and inverted serial outputs from the final stage

Shift Registers Applications

• Automotive electronic systems requiring AEC-Q100 qualification
• Industrial applications necessitating unique site and control change requirements
• General-purpose digital logic circuits utilizing High-Speed CMOS technology

Shift Registers Procurement Notes

Verify that the ordering suffix '-Q' corresponds to the specific automotive qualification and PPAP capability requirements. Confirm the package type matches the design constraints, as this part number specifies the SOIC-16 configuration. Ensure compliance with the manufacturer's RoHS and Pb-Free standards during procurement validation.

Shift Registers Selection Notes

Select this component for designs requiring robust noise immunity and compatibility with standard CMOS or LSTTL outputs. The HC series offers a wide operating voltage range suitable for various logic families. Consider the -Q suffix if the application demands automotive-grade reliability and specific supply chain controls defined by the manufacturer.

Shift Registers Part Context

This device belongs to the MC74HC165A family of 8-bit shift registers. It shares pinout compatibility with LS165 devices while offering improved performance characteristics typical of High-Speed CMOS technology. The -Q suffix indicates adherence to stricter manufacturing controls and automotive qualification standards compared to standard commercial variants.

Shift Registers FAQ

How does the Serial Shift/Parallel Load input control data entry?

When the Serial Shift/Parallel Load input is low, data from the parallel inputs (A-H) is loaded asynchronously. When high, data enters serially at the SA input on the rising edge of the Clock.

What is the function of the two clock inputs?

The Clock and Clock Inhibit inputs function identically as active-high clocks. They can be used independently or combined, with the inhibit input preventing clocking when held high.
