HD74LVCZ16244A

16–bit Buffers / Line Drivers with 3–state Outputs

ADE-205-232 (Z)

1st. Edition

February 1999

Description

The HD74LVCZ16244A has sixteen line drivers with three state outputs in a 48 pin package. This device

is a non inverting buffer and has four active low enables (1G to 4G). Each enable independently controls

four buffers.

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 outputs VO (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)
