DESCRIPTION
The M54/74HC377 is a high speed CMOS OCTALD-TYPE FLIP FLOP fabricated in silicon gate
2
C MOS technology. It has the same high speed performance 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 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.

(*) 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
