INPUT AND OUTPUT EQUIVALENT CIRCUIT
The M54/74HCT74 is a high speed CMOS DUALD
TYPE FLOP WITH PRESET AND CLEAR fabri-
cated in silicon gate C
2
MOS technology. It has the
same high speed performance of LSTTL combined
withtrueCMOSlowpower consumption. Asignal on
the DINPUT istransferred to the QOUTPUTduring
the positive going transition of the clock pulse.
CLEARand PRESET are independent of the clock
and accomplished by alowontheappropriate input.
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.
