DESCRIPTION

The M74HC377 is an high speed CMOS OCTAL
D TYPE FLIP FLOP fabricated with silicon gate

2

MOS technology.

C
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.
