The TC74VHC273 is an advanced high speed CMOS OCTAL
D-TYPE FLIP FLOP fabricated with silicon gate CMOS
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
Qoutputs 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 7V can be
applied to the input pins without regard to the supply
voltage. This device can be used to interface 5V to 3V
systems and two supply systems such as battery back up.
This circuit prevents device destruction due to mismatched
supply and input voltages.
