This document summarizes the results of device modeling and simulation of the TC7S02FU CMOS digital integrated circuit manufactured by Toshiba. Key specifications such as input voltages, output voltages, propagation delay times were measured and found to match simulation results with less than 1% error. Truth tables and signal timing diagrams from circuit simulations validate the correct logic functionality of the device.
