The devices transmit data from the A bus to the B bus or from the B bus to the A bus, depending upon the level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so the buses are effectively isolated. 1 20 2 19 3 18 4 17 5 16 6 15 7 14 8 13 9 12 10 11 VCC OE B1 B2 B3 B4 B5 B6 B7 B8 A2 A1 DIR VCC OE SN54BCT245 . . .
