TC74VHC74F/FN/FT/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHC74F,TC74VHC74FN,TC74VHC74FT,TC74VHC74FK Dual D-Type Flip-Flop with Preset and Clear The TC74VHC74 is an advanced high speed CMOS D-FLIP FLOP fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. 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 5.5 V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages. Note: The JEDEC SOP (FN) 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). 2 2007-10-01 TC74VHC74F/FN/FT/FK Operating Ranges (Note) Characteristics Supply voltage Input voltage Output voltage Operating temperature Input rise and fall time Symbol VCC VIN VOUT Topr dt/dv Rating 2.0 to 5.5 0 to 5.5 0 to VCC −40 to 85 0 to 100 (VCC = 3.3 ± 0.3 V) 0 to 20 (VCC = 5 ± 0.5 V) Unit V V V °C ns/V Note: The operating ranges must be maintained to ensure the normal operation of the device.
