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 C
2
MOS 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.
