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.
When VCC is between 0 and 1.5 V, the device is in the high impedance state during power up or power down.
Low voltage and high-speed operation is suitable at battery drive product (note type personal computer) and low power
consumption extends the life of a battery for long time operation.
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)
