DESCRIPTION

The M74HC273 is an high speed CMOS OCTAL D TYPE FLIP FLOP WITH CLEAR fabricated with silicon gate C

2

MOS technology. Information signals applied to D inputs are transferred to the Q output s on the positive-goi ng edge of the clock pulse.

When the CLEAR

input is held lo w, 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.

1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without

load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. I FLOP), and the total CP D when n pcs of FL IP FLOP operat e can be gained by the following equations: CPD (total) = 32 + 11 x n
