TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
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
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.
High speed: fmax = 185 MHz (typ.) at VCC = 5 V
Low power dissipation: ICC = 2 μA (max) at Ta = 25°C
Compatible with TTL inputs
: VIL = 0.5 V (max)
VIH = 2.1 V (min)
Power down protection is provided on all inputs.
Balanced propagation delays: tpLH ∼− tpHL
Function compatible with 74VHC273
Input terminals are at the opposite side of Output terminals
