DESCRIPTION
The M54/74HC273 is a high speed CMOS OCTAL
D-TYPE FLIP FLOP WITH CLEAR fabricated in silicon gate C2MOS technology. It has the same high
speed performance of LSTTL combined with true
CMOS low power consumption.
Information signals applied to D inputs are transferred to the Q outputs on the positive-going edge
of the clock pulse.
PIN CONNECTIONS (top view)
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.

(*) 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 operting current can be obtained by the following equation. ICC(opr) = CPD •VCC •fIN + ICC/8 (per Flip 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
