SP720
Electronic Protection Array for ESD and
Over-Voltage Protection
The SP720 is an array of SCR/Diode bipolar structures for
ESD and over-voltage protection to sensitive input circuits.
The SP720 has 2 protection SCR/Diode device structures
per input. A total of 14 available inputs can be used to
protect up to 14 external signal or bus lines. Over-voltage
protection is from the IN (pins 1-7 and 9-15) to V+ or V-. The
SCR structures are designed for fast triggering at a
threshold of one +V
BE
diode threshold above V+ (Pin 16) or
a -V
BE
diode threshold below V- (Pin 8). From an IN input, a
clamp to V+ is activated if a transient pulse causes the input
to be increased to a voltage level greater than one V
above V+. A similar clamp to V- is activated if a negative
pulse, one V
BE
less than V-, is applied to an IN input.
Standard ESD Human Body Model (HBM) Capability is:
BE
Refer to Figure 1 and Table 1 for further detail. Refer to
Application Note AN9304 and AN9612 for additional
information.
