The is a TVS Diode Array for general purpose ESD protection. It is an array of SCR/diode bipolar structures for ESD and over-voltage protection to sensitive input circuits. The device has 2 protection SCR/diode 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 1to 3 and pins 5 to 7 to V+ or V-. The device structures is designed for fast triggering at a threshold of one +VBE diode threshold above V+ Pin 8 or a VBE diode threshold below V- Pin 4. 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 VBE above V+. A similar clamp to V- is activated if a negative pulse, one VBE less than V-, is applied to an IN input.
