The M54/74HC273 isa highspeed CMOS OCTAL
D-TYPEFLIPFLOPWITH CLEAR fabricated insili-
con gate C
2
MOS technology. It has the same high
speed performance of LSTTL combined with true
CMOS low powerconsumption.
Information signals applied to D inputs are trans-
ferred to the Q outputs on the positive-going edge
of the clock pulse.
WhentheCLEAR input isheldlow, theQoutput are
inthelowlogic level independent ofthe otherinputs.
All inputs are equipped with protection circuits
against static discharge and transient excess volt-
age.
