SP721
Data Sheet January 1998 File Number 3590.5
Electronic Protection Array for ESD and Over-Voltage Protection [ /Title (SP721 ) /Subject (Electronic Protection Array for ESD and OverVoltage Protection) /Autho r () /Keywords (TVS, Transient Suppression, Protection, ESD, IEC, EMC, Electromagnet ic ComThe SP721 is an array of SCR/Diode bipolar structures for ESD and over-voltage protection to sensitive input circuits. The SP721 has 2 protection SCR/Diode device structures per input. There are a total of 6 available inputs that can be used to protect up to 6 external signal or bus lines. Overvoltage protection is from the IN (Pins 1 - 3 and Pins 5 - 7) to V+ or V-.
