AQ3A–JANUARY2013–REVISEDFEBRUARY201316位双电源总线收发器此收发器具有可配置电压转换和三态输出查询样品:SN74LVC16T245-EP特性控制输入VIH和VIL电平以VCCA电压为基准VCC隔离特性-如果任何一个VCC输入接地(GND)，那么两个端口都处于高阻抗状态过压耐受输入和输出可实现混合电压模式数据通信完全可配置双电源轨设计可使每个端口在整个1.65V-5.5V电源电压范围内运行I关闭支持部分断电模式工作锁断性能超过100mA（符合JESD78，II类规范的要求）静电放电(ESD)保护性能超过JESD22规范要求–2000V人体模型(A114-A)–200V机器模型(A115-A)–1000V充电器件模型(C101)•••••••DGG封装(顶视图)支持国防、航空航天、和医疗应用•••••••(1)受控基线一个组装和测试场所一个制造场所军用（-55°C至125°C）温度范围内可用延长的产品生命周期延长的产品变更通知产品可追溯性可定制工作温度范围(1)1DIR1B11B2GND1B31B4VCCB1B51B6GND1B71B82B12B2GND2B32B4VCCB2B52B6GND2B72B82DIR544434241443332313OE1A11A2GND1A31A4VCCA1A51A6GND1A71A82A12A2GND2A32A4VCCA2A52A6GND2A72A82OE说明这个16位非反相总线收发器使用两个独立的可配置电源轨。A端口被设计用于跟踪VCCA。VCCA可接受从1.65V到5.5V范围内的任意电源电压。B端口被设计用于跟踪VCCB。VCCB可接受从1.65至5.5V间的任一电源电压值。这可实现1.8V，2.5V，3.3V和5V电压节点间的通用低压双向转换。说明（继续）SN74LVC16T245针对两条数据总线间的异步通信而设计。方向控制(DIR)输入和输出使能(OE)输入的逻辑电平激活B端口输出或者A端口输出，或者将两个输出端口都置于高阻抗模式。当B端口输出被激活时，此器件将数据从A总线发送到B总线，而当A端口输出被激活时，此器件将数据从B总线发送到A总线。A端口和B端口上的输入电路一直处于激活状态并且必须施加一个逻辑高或低电平以防止过多的ICC和ICCZ。SN74LVC16T245的设计方式决定了控制引脚（1DIR，2DIR，1OE和2OE）由VCCA供电。该器件完全符合使用I关闭的部分断电应用的规范要求。I关闭电路禁用输出，从而可防止其断电时破坏性电流从该器件回流。Pleasebeawarethatanimportantnoticeconcerningavailability,standardwarranty,anduseincriticalapplicationsofTexasInstrumentssemicondutsconformtght©2013,TexasInstrumentsIncorporatedEnglishDataSheet:SCES843

SN74LVC16T245-EPZHCSAQ3A–JANUARY2013–隔离特性可确保VCC中的任何一个是否接地，然后两个端口都处于高阻抗状态。为了确保加电或断电期间的高阻抗状态，OE应通过一个上拉电阻器被连接至VCC；该电阻器的最小值由驱动器的电流吸收能力来决定。NGINFORMATION(1)TA–55°Cto125°C(1)PACKAGETSSOP-DGGReelof2000Tubeof40ORDERABLEPARTNUMBERCLVC16T245MDGGREPCLVC16T245MDGGEPTOP-SIDEMARKINGLVC16T245MVIDNUMBERV62/12667-01XEV62/12667-01XE-TForthemostcurrentpackageandorderinginformation,seethePackageOptionAddendumattheendofthisdocument,ONTABLE(1)(EACH8-BITSECTION)CONTROLINPUTSOELLH(1)DIRLHXOUTPUTCIRCUITSAPORTEnabledHi-ZHi-ZBPORTHi-ZEnabledHi-ZOPERATIONBdatatoAbusAdatatoBbusIsolationInputcircuitsofthedataI/IAGRAM(POSITIVELOGIC)1DIR12DIR48241OE252OE1A1472A13621B1132B1To Seven Other ChannelsTo Seven Other Channels2Copyright©2013,TexasInstrumentsIncorporated
