TC74LVX74F/FN/FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74LVX74F,TC74LVX74FN,TC74LVX74FT Dual D-Type Flip-Flop with Preset and Clear Note: The TC74LVX74F/ FN/ FT is a high-speed CMOS D-flip flop fabricated with silicon gate CMOS technology. Designed for use in 3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation. This device is suitable for low-voltage and battery operated systems. 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. An input protection circuit ensures that 0 to 5.5V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5V to 3V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages. xxxFN (JEDEC SOP) is not available in Japan. TC74LVX74F TC74LVX74FN Features • High-speed: fmax = 145 MHz (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). 2 2007-10-17 TC74LVX74F/FN/FT Operating Ranges (Note) Characteristics Symbol Rating Unit Supply voltage VCC 2.0 to 3.6 V Input voltage VIN 0 to 5.5 V VOUT 0 to VCC V Operating temperature Topr −40 to 85 °C Input rise and fall time dt/dv 0 to 100 ns/V Output voltage Note: The operating ranges must be maintained to ensure the normal operation of the device.
