TC7MH273FK
Octal D-Type Flip Flop with Clear
The TC7MH273FK 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. 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: 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 1: This parameter is 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 F/F) And the total CPD when n pcs of flip-flop operate can be gained by the following equation: CPD (total) = 22 + 9・n
