Description

The HD74LVCZ245A has eight buffers with three state outputs in a 20 pin package. When (T / R) is high, data flows

from the A inputs to the B outputs, and when (T / R) is low, data flows from the B inputs to the A outputs. A and B bus

are separated by making enable input (OE) 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)

• Ordering Information
