Applications

The SP723 is an array of SCR/Diode bipolar structures for

ESD and over-voltage protection of sensitive input circuits.

The SP723 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. Over-

voltage protection is from the IN (Pins 1 - 3 and Pins 5 - 7)

to V+ or V-.

The SCR structures are designed for fast triggering at a

threshold of one +V

a -V

a clamp to V+ is activated if a transient pulse causes the

input to be increased to a voltage level greater than one

V

pulse, one V

Refer to Fig 1 and Table 1 for further details. Refer to

Application Note AN9304 and AN9612 for further detail.
