HD74LVCZ245A

Octal Bidirectional Transceivers with 3–state Outputs

ADE-205-228A (Z)

2nd. Edition

February 1999

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)
