CXDR75108 CXDR75109具有开漏输出级，而CXDR75108具有推拉输出。CXDR75109L的开漏复位输出需要一个上拉电阻器，该电阻器可以连接到高于VCC的电压。GCXDR75108具有激活的低复位输出，而CXDR75108具有激活的高复位输出。复位比较器被设计成忽略VCC上的快速瞬变，并且输出保证在VCC低至1V的正确逻辑状态。低电源电流使CXDR75108 CXDR75109非常适合用于便携式设备。CXDR75108 CXDR75109有3针SOT-23、TO-92、SC-70-3（SOT-323）和SOT-89封装。CXDR75108 CXDR75109是微处理器（μP）监控电路，用于监控μP和数字系统中的电源。当与+5V，+3.3V，+3.0V供电的电路一起使用时，通过消除外部元件和调整，它们提供了卓越的电路可靠性和低成本。这些电路执行一个单一的功能：每当VCC电源电压下降到预设阈值以下时，它们就断言一个复位信号。适用于各种电源电压操作的重置阈值可用。
