ET5014数据手册ETEK中文资料规格书

描述 Description

The ET5014 is a 4-bit bidirectional level translator in which the input and output ports are switched automatically without direction control. The data path of each channel can be either from I/O_VLn to I/O_VCCn or from I/O_VCCn to I/O_VLn. All of the I/O ports are designed to track two different power supply rails, VCC and VL respectively. Both of the supply voltage are configurable from 1.2V to 5.0V. The VCC and VL supplies are independent which allows a logic signal on the VL side to be translated to either a higher or a lower logic signal voltage on the VCC side, and vice-versa.The ET5014 has high output current capability, which allows the translator to drive high capacitive loads such as most high frequency EMI filters. The enable pin(EN) is used to reduce the power consumption. The EN pin can be used to disable both I/O ports by putting them in 3-state which significantly reduces the supply current from both VCC and VL. The EN signal is referenced to the VL supply.
