74AVC20T245: 20位双电源转换收发器,带可配置电压转换功能;3态

74AVC20T245是20位双电源收发器,可实现双向电压电平转换。该器件可用作两个10位收发器或单路20位收发器。该器件具有四个10位输入输出端口(1An、1Bn和2An、2Bn)、两个输出使能输入(nOE)、两个方向输入(nDIR)和双电源(VCC(A)和VCC(B))。VCC(A)和VCC(B)各自都可以是0.8 V和3.6 V之间的任何电压,因此该器件适用于以下任何低压节点(0.8 V、1.2 V、1.5 V、1.8 V、2.5 V和3.3 V)之间的双向电压电平转换。端口1An和2An、nOE和nDIR以VCC(A)为基准,端口1Bn和2Bn以VCC(B)为基准。1DIR上的高电平允许从1An到1Bn的传输,而1DIR上的低电平则允许从1Bn到1An的传输。nOE上的高电平会使输出呈高阻抗关断状态。

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。在挂起模式下,只要VCC(A)或VCC(B)这两者的其中之一处于GND电平,所有输出端口就都将呈高阻抗关断状态。
