HD74LVC16245A
16-bit Bus Transceivers with 3-state Outputs
ADE-205-120B(Z)
3rd Edition
December 1996
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 high, 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.
