Description
The HD74LVC16244A has sixteen line drivers with three state outputs in a 48 pin package. This device is
a non inverting buffer and has two active low enables (1G to 4G). Each enable independently controls four
buffers. Low voltage and high speed operation is suitable at the battery drive product (note type personal
computer) and low power consumption extends the life of a battery for long time operation.
Features
• V_CC = 2.0 V to 5.5 V
• All inputs V_IH (Max.) = 5.5 V (@V_CC = 0 V to 5.5 V)
• All outputs V_OUT (Max.) = 5.5 V (@V_CC = 0 V or output off state)
• Typical V_OL ground bounce < 0.8 V (@V_CC = 3.3 V, Ta = 25°C)
• Typical V_OH undershoot > 2.0 V (@V_CC = 3.3 V, Ta = 25°C)
• High output current ±24 mA (@V_CC = 3.0 V to 5.5 V)
