Octal Inverted Buffers / Drivers with 3-state Outputs
ADE-205-277 (Z)
1st Edition
April 1999
Description
The HD74LV540A has eight inverter 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
• V_CC = 2.0 V to 5.5 V operation
• All inputs V_IH (Max.) = 5.5 V (@V_CC = 0 V to 5.5 V)
• All outputs V_O (Max.) = 5.5 V (@V_CC = 0 V)
• Typical V_OL ground bounce < 0.8 V (@V_CC = 3.3 V, Ta = 25°C)
• Typical V_OH undershoot > 2.3 V (@V_CC = 3.3 V, Ta = 25°C)
• Output current ±8 mA (@V_CC = 3.0 V to 3.6 V), ±16 mA (@V_CC = 4.5 V to 5.5 V)
