PJ4L40 T/R7 - 7 inch reel, 3K units per reel
PJ4L40 T/R13 - 13 inch reel, 10K units per reel
Note :
1.To protect data lines and the power line, connect pins 2 and 3 directly to the positive supply rail (V
CC
).In this configuration the data
lines are referenced to the supply voltage. An external TVS diode may be added between the supply rail and ground in order to
prevent over-voltage on the supply rail.
2.In applications where no positive supply referenceis available, or complete supply isolation is desired, an external TVS diode may
be used as the reference.The steering diodes will begin to conductwhen the voltage on the protected line exceeds the working
voltage of the TVS (plus one diode drop).
