74LVC(H)2T45: 双电源转换收发器；3态

74LVC2T45；74LVCH2T45是带可实现双向电平转换的3态输出的双位双电源转换收发器。该类器件具有两个2位输入输出端口（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1.2 V至5.5 V之间的任何电压，因此该器件适用于任意低压节点（1.2 V、1.5 V、1.8 V、2.5 V、3.3 V和5.0 V）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。

这些器件完全针对使用IOFF的局部掉电应用设计。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，VCC(A)或VCC(B)为GND电平时，端口A和端口B都处于高阻抗关断状态。

74LVCH2T45中的有源总线保持电路可使未使用的或浮动的数据输入保持在有效逻辑电平。
