| TC7MH273FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic 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. Weight: 0.03 g (typ.) Features * * * * * * * * High speed: fmax = 165 MHz (typ.) (VCC = 5 V) Low power dissipation: ICC = 4 A (max) (Ta = 25C) High noise immunity: VNIH = VNIL = 28% VCC (min) Power down protection is provided on all inputs.

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).
