DESCRIPTION
The 74LV377 is a low–voltage CMOS device and is pin and function
compatible with 74HC/HCT377.
The 74LV377 has eight edge-triggered, D-type flip-flops with
individual D inputs and Q outputs. A common clock (CP) input loads
all flip-flops simultaneously when the data enable (E
state of each D input, one set-up time before the LOW-to-HIGH
clock transition, is transferred to the corresponding output (Q

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability .
2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
