The M54/74HC377 is a high speed CMOS OCTAL-

D-TYPE FLIP FLOP fabricated in silicon gate

C

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.
