LCDA03 THRU LCDA24 TVS ARRAY SERIES
Description
The LCDAXX series of TVS array are designed to
protect sensitive electronics from damage or latch-
up due to ESD and other voltage-induced transient
events. Each device will protect two high-speed
lines. They are bi-directed devices and may be used
on lines where the signal polarities are above and
below ground

Circuit Diagram
The devices are connected as follows:
✔
Pins 1 and 2 are tied together and pins 7 and 8 are tied together providing the protection circuit for one I/O line. Pins 3
and 4 are tied together and pins 5 and 6 are tied together providing the protection circuit for the second I/O line. Since the
device is electrically symmetrical, either side of the connected pairs may be used to protect the lines. The other side of
the pair is used to make the ground connection. The ground connections should be made directly to the ground plane for
best results. The path length is kept as short as possible to reduce the effects of parasitic inductance in the board traces.
