TC7MZ273FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MZ273FK Low-Voltage Octal D-Type Flip-Flop with Clear with 5-V Tolerant Inputs and Outputs The TC7MZ273FK is a high-performance CMOS octal D-type flip-flop. Designed for use in 3.3-V systems, it achieves high-speed operation while maintaining CMOS low power dissipation. The device is designed for low-voltage (3.3-V) applications, but can also be used to interface both inputs and outputs with a 5-V supply environment. D-input signal is sent to Q-output when clock rises. Clear input is Low-active and all flip-flop outputs are reset Low. All inputs are equipped with protection circuits to guard against static discharge. Weight: 0.03 g (typ.)

Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).
