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

• VCC = 2.0 V to 5.5 V

• All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V)

• All outputs VOUT (Max.) = 5.5 V (@VCC = 0 V or output off state)

• Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C)

• Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C)

• High output current ±24 mA (@VCC = 3.0 V to 5.5 V)

• Ordering Information
