TC74VHCT74AF/AFN/AFT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHCT74AF,TC74VHCT74AFN,TC74VHCT74AFT Dual D-Type Flip-Flop with Preset and Clear The TC74VHCT74 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. The input voltage are compatible with TTL output voltage. This device may be used as a level converter for interfacing 3.3 V to 5 V system. Input protection and output circuit ensure that 0 to 5.5 V can be applied to the input and output (Note) pins without regard to the supply voltage. These structure prevents device destruction due to mismatched supply and input/output voltages such as battery back up, hot board insertion, etc. Note: TC74VHCT74AFN TC74VHCT74AFT • High speed: fmax = 160 MHz (typ.) at VCC = 5 V • Low power dissipation: ICC = 2 μA (max) at Ta = 25°C • Compatible with TTL outputs: VIL = 0.8 V (max) VIH = 2.0 V (min) • Power down protection is provided on all inputs and outputs ∼ tpHL Balanced propagation delays: tpLH − • TC74VHCT74AF VCC = 0 V Features • 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).
