MC74HC165ADTR2G-Q

Shift Registers Overview

The MC74HC165ADTR2G-Q is an 8-bit serial or parallel-input/serial-output shift register manufactured by onsemi. It utilizes high-performance silicon-gate CMOS technology and operates within a voltage range of 2.0 V to 6.0 V. The device features asynchronous parallel loading capabilities and supports serial shifting via rising edges of either the Clock or Clock Inhibit inputs. It provides complementary outputs from the final stage and includes independent clock inputs that can function as active-high clock inhibits. The component is housed in a TSSOP-16 package.

Shift Registers Feature Summary

• Supports both asynchronous parallel data loading and serial shifting operations
• Features dual clock inputs allowing for independent clock sources or clock inhibit functionality
• Provides complementary non-inverted and inverted outputs from the eighth stage
• Compatible with standard CMOS, NMOS, and TTL logic families

Shift Registers Applications

• Parallel-to-serial data conversion circuits
• Serial-to-parallel data expansion systems
• Input port expansion for microcontrollers
• Key scanning matrices

Shift Registers Procurement Notes

Verify the specific suffix 'Q' indicates AEC-Q100 qualification and PPAP capability requirements unique to automotive applications. Confirm the 'DT' designation corresponds to the TSSOP-16 package variant. Ensure compliance with RoHS and halogen-free standards during procurement validation.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with simultaneous parallel load and serial shift capabilities is required. The HC series offers a wide operating voltage range suitable for various digital logic levels. Consider the Q-suffix if the application demands automotive-grade site control and quality assurance protocols.
