Description
The HD74LVC16245A has sixteen two direction buffers, for the fittest at two direction bus lines with three state
outputs. A direction control input, DIR. When DIR is high, data flows from the A inputs to the B outputs. When DIR
is low, data flows from the B inputs to the A outputs. When enable inputs (G) is high, disables both A and B ports by
placing then in a high impedance. 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)
