Description
The 74HC377TTR is a high-speed CMOS octal D type flip-flop manufactured using silicon gate C2MOS technology. It has eight D-type inputs and eight corresponding Q outputs. The Q outputs are triggered by the positive going edge of the clock pulse when the enable input G is low. The clock triggering is not directly related to the transition time of the positive going pulse. The D input signal has no effect at the output when the clock input is at either the high or low level. All inputs are equipped with protection circuitry against static discharge and transient excess voltage.
