DESCRIPTION

The M54/74HC377 isa high speedCMOS OCTAL­D-TYPE FLIP FLOP fabricated in silicon gate
C2MOStechnology.It hasthesamehighspeedper­formance of LSTTL combined with true CMOS low
powerconsumption.

Information at the D inputsmeeting the setup time
requirements is transferredto the Q outputson the
positive-going edge of the clock pulse if the enable
inputGislow. Clocktriggering occursat aparticular
voltage level and is not directly related to the transi­tiontime ofthepositive-going pulse. Whentheclock
inputis ateitherthehigh orlowlevel,theDinputsig­nal has no effect at the output. All inputs are
equipped with protection circuits against static dis­charge and transientexcess voltage.
