• Manufacturer Part Number: STE0514D52RG
• Description: Four-Line ESD Protection Array
• Manufacturer: STANSON [Stanson Technology]

Four-Line ESD Protection Array
Working voltage 5V
APPLICATION NOTE
Device Connection for Protection of Four Data Lines
STE0514 is designed to protect up to four data lines. The device is connected as follows :
1. The TVS protection of four I/O lines is achieved by connecting pins 1,3, 4, 6 to the data
Circuit Board Layout Recommendations for Suppression of ESD
Good circuit board layout is critical for the suppression of ESD induced transients. The
following guidelines are recommended:
1. Place the TVS near the input terminals or connectors to restrict transient coupling.
2. Minimize the path length between the TVS and the protected line.
3. Minimize all conductive loops including power and ground loops.
4. The ESD transient return path to ground should be kept as short as possible.
5. Never run critical signals near board edges
6. Use ground planes whenever possible.
lines. Pin 2 is connected to ground. The ground connection 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.
