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.
