隔离单元以及集成电路
摘要：
本发明的一实施例提供一种隔离单元以及集成电路，其中隔离单元用以将第二电源域与第一电源域隔离，包括输入端、输出端、第一电源端以及第二电源端。该输入端，用以接收该第一电源域的第一信号。该输出端，用以输出具有预定逻辑电平的输出信号，并将该输出信号传送至该第二电源域。该第一电源端接收来自电源的电压，该电源是不同于该第一电源域的第一电源，且该电压用以供电给该隔离单元。本发明提供的隔离单元以及集成电路可以确保来自不供电模式的电源域的信号的逻辑电平可以固定在预定逻辑电平。
摘要（英）：

An embodiment of the invention provides an isolation cell for isolating a second power domain from a first power domain, and an integrated circuit. The isolation cell includes an input terminal capable of receiving a first signal of the first power domain, an output terminal capable of outputting an output signal with a predetermined logic state to the second power domain, a first power terminal and a second power terminal. The first power terminal is capable of receiving a voltage from a power source, the power source is different from a first power source of the first power domain, and the isolation cell is powered by the voltage. The isolation cell and the integrated circuit ensure that the signal logic level of power domain from non-power supply mode can be fixed on the predetermined logic level.
