WhenOE is low, the devices pass data from the A inputs to the Y outputs. When OE is high, the outputs are in thehigh-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.Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level. Use of pullupor pulldown resistors with the bus-hold circuitry is not recommended.These devices are fully specified for hot-insertion applications using Ioff and power-up 3-state. The Ioff circuitrydisables the outputs, preventing damaging current backflow through the devices when they are powered down.The power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down,which prevents driver conflict.SN74LVTH244A...GQN OR ZQN PACKAGE(TOP VIEW)1ABCDE234ABCDEterminal assignments11A11A21A31A4GND21OE2A42Y32A22Y13VCC2Y42A32Y22A142OE1Y11Y21Y31Y4FUNCTION TABLE(each buffer)INPUTSOELLHAHLXOUTPUTYHLZ2POST OFFICE BOX 655303 DALLAS, TEXAS 75265•元器件交易网www.cecb2b.comSN54LVTH244A, SN74LVTH244A3.3ĆV ABT OCTAL BUFFERS/DRIVERSWITH 3ĆSTATE OUTPUTSSCAS586J − DECEMBER 1996 − REVISED OCTOBER 2003logic diagram (positive logic)1OE12OE191A12181Y12A11192Y11A24161Y22A21372Y21A36141Y32A31552Y31A48121Y42A41732Y4Pin numbers shown are for the DB, DW, FK, J, NS, PW, RGY, and W packages.absolute maximum ratings over operating free-air temperature range (unless otherwise noted)†Supply voltage range, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −0.5 V to 4.6 VInput voltage range, VI (see Note 1) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −0.5 V to 7 VVoltage range applied to any output in the high-impedanceor power-off state, VO (see Note 1) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −0.5 V to 7 VVoltage range applied to any output in the high state, VO (see Note 1) . . . . . . . . . . . . . −0.5 V to VCC + 0.5 VCurrent into any output in the low state, IO:SN54LVTH244A 96 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . mASN74LVTH244A 128 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . mACurrent into any output in the high state, IO (see Note 2):SN54LVTH244A . . . . . . . . . . . . . . . . . . . . . . 48 mASN74LVTH244A 64 . . . . . . . . . . . . . . . . . . . . . . mAInput clamp current, IIK (VI < 0) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −50 mAOutput clamp current, IOK (VO < 0) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −50 mAPackage thermal impedance, θJA (see Note 3):DB package . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 70°C/W(see Note 3):DW package . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 58°C/W(see Note 3):GQN/ZQN package . . . . . . . . . . . . . . . . . . . . . . . . . . . 78°C/W(see Note 3):NS package . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 60°C/W(see Note 3):PW package . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 83°C/W(see Note 4):RGY package . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 37°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.
