The M54/74HCT273 isa 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.
