Octal D-Type Flip Flop with Clear
The TC74VHCT9273 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.
The input voltage are compatible with TTL output voltage.
This device may be used as a level converter for interfacing 3.3
V to 5 V system.
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.
The CLR input and CK input have hysteresis between the
positive-going and negative-going thresholds. Thus the
TC74VHCT9273 is capable of squaring up transitions of slowly
changing input signals and provides an improved noise
immunity.
It is easy to wire on the board because Input terminals are at
the opposite side of Output terminals.
An input protection circuit ensures that 0 to 5.5 V can be
applied to the input pins without regard to the supply voltage.
