DESCRIPTION The M74HC377 is an high speed CMOS OCTAL D TYPE FLIP FLOP fabricated with silicon gate C2MOS technology. 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 transition time of the positive going pulse. When the clock input is at either the high or low level, the D input signal has no effect at the output. All inputs are equipped with protection circuits against static discharge and transient excess voltage.

CIN CPD
Input Capacitance Power Dissipation Capacitance (note 1)
1) CPD is defined as the value of the IC's internal equivalent capacitance which is calculated from the operating current consumption without load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC
