HD74LVCZ240A
Octal Buffers / Line Drivers with 3–state Outputs
ADE-205-229A (Z)
2nd. Edition
February 1999
Description
The HD74LVCZ240A has eight inverter drivers with three state outputs in a 20 pin package. This device is
a inverting buffer and has two active low enables (1
G
and 2
G
). 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.
