The M54/74HCT273 isa highspeedCMOSOCTAL
D-TYPEFLIPFLOPWITH CLEAR fabricated insili-
con gate C
2
MOS 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 Qoutputs
on thepositive-going edge of the clock pulse.
WhentheCLEAR input isheldlow, theQoutput are
inthelowlogic level independent ofthe otherinputs.
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-
signedto directly interface HSC
2
MOS systems with
TTL and NMOScomponents. They are also plug in
replacements for LSTTL devices giving a reduction
of power consumption. All inputs are equipped with
protection circuits against staticdischarge and tran-
sient excess voltage.
