DESCRIPTION
The M54/74HCT273 is a high speed CMOS OCTAL
D-TYPE FLIP FLOP WITH CLEAR fabricated in sili-
con 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.
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 volt-
age. This integrated circuit has input and output
characteristics that are fully compatible with 54/74
LSTTL logic families. M54/74HCT devices are de-
signed to directly interface HSC2MOS systems with
TTL and NMOS components. They are also plug in
replacements for LSTTL devices giving a reduction
of power consumption. All inputs are equipped with
protection circuits against static discharge and tran-
sient 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
