Charged-Device Model (C101)OperationThis single-bit noninverting bus transceiver uses two separate configurable power-supply rails.The SN74AVC1T45is optimized to operate with V CCA /V CCB set at 1.4V to 3.6V.It is operational with V CCA /V CCB as low as 1.2V.The A port is designed to track V CCA .V CCA accepts any supply voltage from 1.2V to 3.6V.The B port is designed to track V CCB .V CCB accepts any supply voltage from 1.2V to 3.6V.This allows for universal low-voltage bidirectional translation between any of the 1.2-V,1.5-V,1.8-V,2.5-V,and 3.3-V voltage nodes.ORDERING INFORMATIONT

for asynchronous communication between two data buses.The logic levels of the direction-control (DIR)input activate either the B-port outputs or the A-port outputs.The device transmits data from the A bus to the B bus when the B-port outputs are activated and from the B bus to the A bus when the A-port outputs are activated.The input circuitry on both A and B ports always is active and must have a logic HIGH or LOW level applied to prevent excess I CC and I CCZ .The SN74AVC1T45is designed so that the DIR input is powered by V CCA .This device is fully specified for partial-power-down applications using I off .The I off circuitry disables the outputs,preventing damaging current backflow through the device when it is powered down.The V CC isolation feature ensures that if either V CC input is at GND,then both ports are in the high-impedance state.NanoFree™package technology is a major breakthrough in IC packaging concepts,using the die as the package.FUNCTION TABLE (1)INPUT

formulas:•t PZH (DIR to A)=t PLZ (DIR to B)+t PLH (B to A)•t PZL (DIR to A)=t PHZ (DIR to B)+t PHL (B to A)•t PZH (DIR to B)=t PLZ (DIR to A)+t PLH (A to B)•t PZL (DIR to B)=t PHZ (DIR to A)+t PHL (A to B)In a bidirectional application,these enable times provide the maximum delay from the time the DIR bit is switched until an output is expected.For example,if the SN74AVC1T45initially is transmitting from A to B,then the DIR bit is switched;the B port of the device must be disabled before presenting it with an input.After the B port has been disabled,an input signal applied to it appears on the corresponding A port after the specified propagation delay.元器件交易网PACKAGING INFORMATIONOrderable Device Status(1)PackageType PackageDrawingPins PackageQtyEco Plan(2)Lead/Ball Finish MSL

classification:Pb-Free(RoHS),Pb-Free(RoHS Exempt),or Green(RoHS&no Sb/Br)-please check /productcontent for the latest availability information and additional product content details.TBD:The Pb-Free/Green conversion plan has not been defined.Pb-Free(RoHS):TI's terms"Lead-Free"or"Pb-Free"mean semiconductor products that are compatible with the current RoHS requirements for all6substances,including the requirement that lead not exceed0.1%by weight in homogeneous materials.Where designed to be soldered at high temperatures,TI Pb-Free products are suitable for use in specified lead-free processes.Pb-Free(RoHS Exempt):This component has a RoHS exemption for either1)lead-based flip-chip solder bumps used between the die and package,or2)lead-based die adhesive used between the die and leadframe.The component is otherwise considered Pb-Free(RoHS compatible)as defined above.Green(RoHS&no Sb/Br):TI defines"Green"to mean Pb-Free(RoHS compatible),and free of Bromine(Br)and Antimony(Sb)based flame retardants(Br or Sb do not exceed0.1%by weight in homogeneous material)(3)MSL,Peak Temp.--The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications,and peak solder temperature.Important Information and Disclaimer:The information provided on this page represents TI's knowledge and belief as of the date that it is
