DESCRIPTION
The M54/74HC377 is a high speed CMOS OCTAL-
D-TYPE FLIP FLOP fabricated in silicon gate
C2MOS technology. It has the same high speed 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.

(*) 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 operting current can be obtained by the following equation. ICC(opr) = CPD •VCC •fIN + ICC
