74AVCH2T45DC: 双位双电源电压电平转换器/收发器;3态

74AVCH2T45是双位双电源收发器,可实现双向电平转换。该器件具有两个数据输入输出端口(nA和nB)、一个方向控制输入(DIR)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nA和DIR以VCC(A)为基准,针脚nB以VCC(B)为基准。DIR上的高电平允许从nA传输到nB,而DIR上的低电平则允许从nB传输到nA。

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)这两者之一处于GND电平,A和B就都处于高阻抗关断状态。

74AVCH2T45具有有源总线保持电路,提供该电路是为了使未使用的或浮动的数据输入保持在有效逻辑电平。该器件因此特性而无需外部上拉或下拉电阻。
