Shift Registers Procurement Notes

Verify the specific suffix E2 against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Confirm availability status as components may be subject to discontinuation or lifecycle changes. Ensure the SOP-16 package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Shift Registers Selection Notes

Select this component when an 8-bit serial-to-parallel converter with three-state outputs is required within the 4000B logic family. Consider the operating voltage range and propagation delay characteristics relative to the system clock speed. Verify that the SOP-16 package form factor fits the available board space and assembly constraints.

Shift Registers Part Context

This device is part of ROHM's 4000B series of high-voltage CMOS logic integrated circuits. The series includes various logic gates, flip-flops, and registers designed for robust performance in industrial and consumer applications.
