HD74LV125A Quad. Bus Buffer Gates with 3-state Outputs REJ03D0315–0300Z (Previous ADE-205-245A (Z)) Rev.3.00 Jun. 03, 2004 Description The HD74LV125A features independent line drivers with three state outputs. Each output is disabled when the associated output enable (OE) input is high. To ensure the high impedance state during power up or power down, OE should be connected to VCC through a pull-down resistor; the minimum value of the resistor is determined by the current souring capability of the driver. Low-voltage and high-speed operation is suitable for the battery-powered products (e.g., notebook computers), and the low-power consumption extends the battery life. Features • • • • • • • VCC = 2.0 V to 5.5 V operation All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V) All outputs VO (Max.) = 5.5 V (@VCC = 0 V) Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C) Typical VOH undershoot > 2.3 V (@VCC = 3.3 V, Ta = 25°C) Output current ±8 mA (@VCC = 3.0 V to 3.6 V), ±16 mA (@VCC = 4.5 V to 5.5 V) Ordering Information Part Name Package Type Package Code Package Abbreviation Taping Abbreviation (Quantity) HD74LV125AFPEL HD74LV125ARPEL HD74LV125ATELL SOP–14 pin(JEITA) SOP–14 pin(JEDEC) TSSOP–14 pin FP–14DAV FP–14DNV TTP–14DV FP RP T EL (2,000 pcs/reel) EL (2,500 pcs/reel) ELL (2,000 pcs/reel) Note: Please consult the sales office for the above package availability.
