PIN AND FUNCTION COMPATIBLE

WITH 54/74LS74

The M54/74HC74 is a high speed CMOS DUAL D

TYPE FLOP WITH PRESET AND CLEAR fabri-

cated in silicon gate C

2MOS technology. It has the

same high speed performance of LSTTL combined

with true CMOS low power consumption. A signal on

the D INPUT is transferred to the Q OUTPUT during

the positive going transition of the clock pulse.

CLEAR and PRESET are independent of the clock

and accomplished by a low on the appropriate input.

All inputs are equipped with protection circuits

against static discharge and transient excess volt-

age.
