Description
The HD74LVC16245A has sixteen two direction buffers, for the fittest at two direction bus lines with three state
outputs. A direction control input, DIR. When DIR is high, data flows from the A inputs to the B outputs. When DIR
is low, data flows from the B inputs to the A outputs. When enable inputs (G) is high, disables both A and B ports by
placing then in a high impedance. 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.
