74AVC8T245: 8位双电源转换收发器,带可配置电压转换功能;3态

74AVC8T245是8位双电源收发器,可实现双向电平转换。该器件具有两个8位输入输出端口(An和Bn)、一个方向控制输入(DIR)、一个输出使能输入(OE)和双电源针脚(VCC(A)和VCC(B))。VCC(A)和VCC(B)都可以是0.8 V和3.6 V之间的任何电压,因此该器件适用于任何低压节点(1.2 V、1.5 V、1.8 V、2.5 V和3.3 V)之间的转换。针脚An、OE和DIR以VCC(A)为基准,针脚Bn以VCC(B)为基准。DIR上的高电平允许从An传输到Bn,而DIR上的低电平则允许从Bn传输到An。输出使能输入(OE)可用于禁用输出,因此总线能得到有效隔离。

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,An和Bn就都处于高阻抗关断状态。
