4 / 8 page ![]() 4 Application Information Pin Connection in PCB lines simultaneously. The pin connection is shown in the figure below. Four parallel data lines, from inner IC to I/O port connector, coule connect to T0504SP four I/O pins directly. Pin 3 of T0504SP is the GND pin, which should connect to the GND of PCB. The wire should be as short as possible in order to minimize the parasitic inductance. PCB Layout Guidelines For optimum ESD protection and the whole circuit performance, the following PCB layout guidelines are recommended: should be as short as possible. It could reduce the ESD transient return path to GND. The vias connecting T0504SP GND pins to the PCB GND should be wide . Place possible. It could reduce the parasitic inductance and restrict ESD coupling into adjacent traces. Avoid running critical signals near board edges. T0504SP GND pin to the PCB GND rail path T0504SP as close to the connector port as T0504SP provides ESD protection for four data I/O1 I/O2 I/O4 I/O3 F p igure 1 T0504SP in connection in PCB Ultra-Low Capacitance ESD Protection Device Chip Integration Technology Corporation GND To I/O Port Connector Date lines To I/O Port Connector Date lines To Inner IC Date lines To Inner IC Date lines T0504SP □ □ □ □ Document ID : DS-22V15 Revised Date : 2017/07/20 Revision : C |
