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-.
SCR结构设计用于在一 +V的阈值下快速触发是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 V是above V+. A similar clamp to V- is activated if a negative pulse, one V是小于v-，应用于输入。
