HD74LV244A Octal Buffers / Drivers with 3-state Outputs REJ03D0328–0300Z (Previous ADE-205-246A (Z)) Rev.3.00 Jun. 24, 2004 Description The HD74LV244A has eight line drivers with three-state outputs in a 20-pin package. Four non-inverters are included in one circuit. Each circuit can be independently controlled by the enable signal 1OE or 2OE, which enables outputs when receiving a low-level signal. Low-voltage operation is suitable for 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) HD74LV244AFPEL SOP–20 pin (JEITA) FP–20DAV FP EL (2,000 pcs/reel) HD74LV244ARPEL HD74LV244ATELL SOP–20 pin (JEDEC) TSSOP–20 pin FP–20DBV TTP–20DAV RP T EL (1,000 pcs/reel) ELL (2,000 pcs/reel) Note: Please consult the sales office for the above package availability.
