M74HC377B1R

八路D型触发器 OCTAL D TYPE FLIP FLOP

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 Gis low. Clock triggering occurs at a particular voltage level and is not directly relatedto 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.
