Overview
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.
