Nexperia 74AVC1T45双电源电压电平转换器/收发器

NXP Semiconductors 74AVC1T45是带3态输出的一位双电源收发器，可实现双向电平转换。该器件具有两个1位输入输出端口（A和B）、一个方向控制输入(DIR)和双电源引脚（V_CC(A) 和V_CC(B))。V_CC(A) 和V_CC(B) 都可以是0.8V和3.6V之间的任何电压，因此该器件适用于任何低压节点（0.8 V、1.2 V、1.5 V、1.8 V、2.5 V和3.3 V）之间的转换。引脚A和DIR以V_CC(A) 为基准，引脚B以V_CC(B)为基准。DIR上的高电平允许从A传输到B，而DIR上的低电平则允许从B传输到A。该器件完全适合使用IOFF的局部掉电应用。IOFF电路可禁用输出，防止断电时任何破坏性回流电流通过该器件。在休眠模式下，只要V_CC(A) 或V_CC(B) 这两者之一处于GND电平，A和B就都处于高阻抗关断状态。

A HIGH on DIR allows transmission from A to B and a LOW on DIR allows transmission from B to A. The device is fully specified for partial-power-down applications using I_OFF. The I_OFF circuitry disables the output, preventing any damaging backflow current through the device when it is powered down. In suspend mode when either V_CC(A) or V_CC(B) are at A and B are in the high-impedance OFF-state. A and B are in the high-impedance OFF-state.
