Overview
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.
