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 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.
