| TC74LCX74F/FN/FT/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74LCX74F,TC74LCX74FN,TC74LCX74FT,TC74LCX74FK Low-Voltage Dual D-Type Flip-Flop with 5-V Tolerant Inputs and Outputs The TC74LCX74 is a high-performance CMOS D-type flip-flop. Designed for use in 3.3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation. The device is designed for low-voltage (3.3 V) VCC applications, but it could be used to interface to 5-V supply environment for inputs. The signal level applied to the D input is transferred to Q output during the positive going transition of the CK pulse. CLR and PR are independent of the CK and are accomplished by setting the appropriate input low. All inputs are equipped with protection circuits against static discharge. Note: xxxFN (JEDEC SOP) is not available in Japan.

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). Note 2: VCC = 0 V Note 3: High or low state. IOUT absolute maximum rating must be observed.
