description  
The SN74F377A is a monolithic, positive-edge-triggered, octal, D-type flip-flop with clock enable inputs. The  
SN74F377A features a latched clock enable (CE) input.  
Information at the data (D) inputs meeting the setup time requirements is transferred to the Q outputs on the  
positive-going edge of the clock pulse if CE is low. Clock triggering occurs at a particular voltage level and is  
not directly related to 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. The circuits are designed to prevent false clocking by transitions at the CE  
input.  
The SN74F377A is characterized for operation from 0°C to 70°C.
