DESCRIPTION
The M54/74HC377 is a high speed CMOS OCTAL-
D-TYPE FLIP FLOP fabricated in silicon gate
C2MOS technology. It has the same highspeed per-
formance of LSTTL combined with true CMOS low
power consumption.
Information at the D inputs meeting the setup time
requirements is transferred to the Q outputs on the
positive-going edge of the clock pulse if the enable
input G is low. Clock triggering occurs at a particular
voltage level and is not directly related to the transi-
tion time of the positive-going pulse. When the clock
input is at either the high or low level, the D input sig-
nal has no effect at the output. All inputs are
equipped with protection circuits against static dis-
charge and transient excess voltage.
