DESCRIPTION

The M74HC377 is an high speed CMOS OCTAL

D TYPE FLIP FLOP fabricated with silicon gate

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.
