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
• 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)
