RD74LVC16245B 16-bit Bus Transceivers with 3-state Outputs REJ03D0529–0100 Rev.1.00 Apr. 18, 2005 Description The RD74LVC16245B 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.
