The Ioff circuitry disables the outputs,preventing damaging current backflow through the device when it is powered down.The VCC isolation feature ensures that if either VCC input is at GND, both ports are in the high-impedance state.To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullupresistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.GQL OR ZQL PACKAGE(TOP VIEW)1ABCDEFGHJKFUNCTION TABLE(each 8-bit section)INPUTSOELLHDIRLHXOPERATIONB data to A busA data to B busIsolation23456ABCDEFGHJKterminal assignments11DIR1B21B41B61B82B12B32B52B72DIR2NC1B11B31B51B72B22B42B62B8NCGNDVCCBGNDNCGNDVCCAGNDNC3NCGNDVCCBGND4NCGNDVCCAGND5NC1A11A31A51A72A22A42A62A8NC61OE1A21A41A61A82A12A32A52A72OENC − No internal connectionlogic diagram (positive logic)1DIR12DIR48241OE252OE1A1472A13621B1132B1To Seven Other ChannelsTo Seven Other Channels2POST OFFICE BOX 655303 DALLAS, TEXAS 75265•元器件交易网www.cecb2b.comSN74AVC16T24516ĆBIT DUALĆSUPPLY BUS TRANSCEIVERWITH CONFIGURABLE VOLTAGE TRANSLATION AND 3ĆSTATE OUTPUTSSCES551A – FEBRUARY 2004 – REVISED AUGUST 2004absolute maximum ratings over operating free-air temperature range (unless otherwise noted)†Supply voltage range, VCCA and VCCB . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −0.5 V to 4.6 VInput voltage range, VI (see Note 1):I/O ports (A port) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −0.5 V to 4.6 VI/O ports (B port) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −0.5 V to 4.6 VControl inputs . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −0.5 V to 4.6 VVoltage range applied to any output in the high-impedance or power-off state, VO(see Note 1):A port . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −0.5 V to 4.6 VB port . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −0.5 V to 4.6 VVoltage range applied to any output in the high or low state, VO(see Notes 1 and 2):A port . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −0.5 V to VCCA + 0.5 VB port . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −0.5 V to VCCB + 0.5 VInput clamp current, IIK (VI < 0) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −50 mAOutput clamp current, IOK (VO < 0) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −50 mAContinuous output current, IO . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ±50 mAContinuous current through each VCCA, VCCB, and GND . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ±100 mAPackage thermal impedance, θJA (see Note 3):DGG package . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 70°C/WDGV package . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 58°C/WGQL/ZQL package . . . . . . . . . . . . . . . . . . . . . . . . . . . 42°C/WStorage temperature range, Tstg −65. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . °C to 150°C†Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.
