74AVCH4T245是4位双电源收发器,可实现双向电平转换。该器件可用作两个2位收发器或一个4位收发器。该器件具有两个2位输入输出端口(nAn和nBn)、一个方向控制输入(nDIR)、一个输出使能输入(nOE)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nAn、nOE和nDIR以VCC(A)为基准,针脚nBn以VCC(B)为基准。nDIR上的高电平允许从nAn到nBn的传输,而nDIR上的低电平则允许从nBn到nAn的传输。输出使能输入(nOE)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,nAn和nBn输出就都处于高阻抗关断状态。通电侧的总线保持电路始终保持有源状态。
74AVCH4T245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。
