HD74LVC245A
Octal Bidirectional Transceivers with 3-state Outputs

Description
The HD74LVC245A 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. Low voltage and high-speed operation is suitable at the battery
drive product (note type personal computer) and low power consumption extends the life of a battery for long time
operation.
