Information signals applied to D inputs are
transferred to the Q outputs on the positive-going
edge of the clock pulse.
When the CLEAR input is held low, the Q output
are in the low logic level independent of the other
inputs.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
DESCRIPTION
The M54HC273 is an high speed CMOS OCTAL
D TYPE FLIP FLOP WITH CLEAR fabricated with
2
silicon gate C MOS technology.

1) C is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without
PD
load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. I
= C x V x f + I /8 (per FLIP
CC(opr)
PD CC IN CC
FLOP), and the total CPD when n pcs of FLIP FLOP operate can be gained by the following equations: CPD (total) = 32 + 11 x n
