描述 Description

The HD74LVCZ16245A has sixteen two direction buffers, for the fittest at two direction bus lines with three state outputs in a 48 pin package. When (DIR) is high, data flows from the A inputs to the B outputs, and when (DIR) is low, data flows from the B inputs to the A outputs. A and B bus are separated by making enable input (G) high level.

特性 Features

? VCC = 2.7 to 5.5 V

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

? All inputs / outputs VI/O (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 impedance state during power up and power down

? Power off disables outputs, permitting live insertion

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