HD74LVC2244A Octal Buffers / Line Drivers with 3–state Outputs REJ03D0376–0300 (Previous ADE-205-234A (Z)) Rev.3.00 Aug. 20, 2004 Description The HD74LVC2244A has eight line drivers with three state outputs in a 20 pin package. This device is a noninverting buffer and has two active low enables (1G and 2G). Each enable independently controls four buffers. All outputs, which are designed to sink up to 12mA, include equivalent 26 Ω resistors to reduce overshoot and undershoot. Low voltage and high-speed operation is suitable at battery drive product (note type personal computer) and low power consumption extends the life of a battery for long time operation. Features • • • • • • • • VCC = 1.65 to 5.5 V All inputs VIH (Max) = 5.5 V (@VCC = 0 to 5.5 V) All outputs VO (Max) = 5.5 V (@VCC = 0 V or output off state) Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C) Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C) High output current ±12mA (@VCC = 3.0 to 5.5 V) All outputs have equivalent 26 Ω series resistors, so no external resistors are required Ordering Information Part Name Package Type Package Code Package Abbreviation Taping Abbreviation (Quantity) HD74LVC2244AFPEL HD74LVC2244ATELL SOP–20 pin (JEITA) TSSOP–20 pin FP–20DAV TTP–20DAV FP T EL (2,000 pcs/reel) ELL (2,000 pcs/reel) Note: Please consult the sales office for the above package availability.
