HD74LV541A

HD74LV541A Octal Buffers / Drivers with 3-state Outputs ADE-205-278 (Z) 1st Edition April 1999 Description The HD74LV541A has eight line drivers with three state outputs in a 20 pin package. When OE1 and OE2 is low level, this drivers set up output is enable. 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) Function Table Inputs OE1 L L H X Note: H: L: X: Z: High level Low level Immaterial High impedance OE2 L L X H A L H X X Output Y L H Z Z HD74LV541A Pin Arrangement OE1 1 A1 2 A2 3 A3 4 A4 5 A5 6 A6 7 A7 8 A8 9 GND 10 20 VCC 19 OE2 18 Y1 17 Y2 16 Y3 15 Y4 14 Y5 13 Y6 12 Y7 11 Y8 (Top view) 2 HD74LV541A Absolute Maximum Ratings Item Supply voltage range Input voltage range* 1 1, 2 Symbol VCC VI VO Ratings –0.5 to 7.0 –0.5 to 7.0 –0.5 to VCC + 0.5 –0.5 to 7.0 Unit V V V Conditions Output voltage range* Output: H or L VCC: OFF or Output: Z Input clamp current Output clamp current Continuous output current Continuous current through VCC or GND Maximum power dissipation at Ta = 25°C (in still air)*3 I IK I OK IO I CC or IGND PT –...
