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 V_CC 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
• V_CC = 2.7 to 5.5 V
• All inputs V_IH (Max) = 5.5 V (@V_CC = 0 to 5.5 V)
• All outputs V_O (Max) = 5.5 V (@V_CC = 0 V or output off state)
• Typical V_OL ground bounce < 0.8 V (@V_CC = 3.3 V, Ta = 25°C)
• Typical V_OH undershoot > 2.0 V (@V_CC = 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 (@V_CC = 3.0 to 5.5 V)
