TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74VHC9273P,TC74VHC9273FT,TC74VHC9273FK
Octal D-Type Flip Flop with Clear
The TC74VHC9273 is an advanced high speed CMOS OCTAL D-TYPE 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. Information signals applied to D inputs are transferred to the Q outputs on the positive going edge of the clock pulse. When the CLR input is held "L", the Q outputs are at a low logic level independent of the other inputs. The CLR input and CK input have hysteresis between the positive-going and negative-going thresholds. Thus the TC74VHC9273 is capable of squaring up transitions of slowly changing input signals and provides an improved noise immunity. It is easy to wire on the board because Input terminals are at the opposite side of Output terminals. 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.

Absolute Maximum Ratings (Note1)
Characteristics Supply voltage range DC input voltage DC output voltage Input diode current Output diode current DC output current DC VCC/ground current Power dissipation Storage temperature Symbol VCC VIN VOUT IIK IOK IOUT ICC PD Tstg Rating -0.5 to 7.0 -0.5 to 7.0 -0.5 to VCC + 0.5 -20 20 25 75 500 (DIP) (Note 2)/180(TSSOP/VSSOP) -65 to 150 Unit V V V mA mA mA mA mW C
Note 1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even destruction. 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: 500 mW in the range of Ta = -40 to 65C. From Ta = 65 to 85C a derating factor of -10 mW/C shall be applied until 300 mW.

Note: The operating ranges must be maintained to ensure the normal operation of the device. Unused inputs must be tied to either VCC or GND.

Note 1: Parameter guaranteed by design. tosLH = |tpLHm - tpLHn|, tosHL = |tpHLm - tpHLn| Note 2: CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load. Average operating current can be obtained by the equation: ICC (opr) = CPD*VCC*fIN + ICC/8 (per bit) And the total CPD when n pcs.of flip flop operate can be calculated by the following equation: CPD (total) = 7 + 4*n
