Features

EW) A2 A1 OEBA1 NC VCC B1 B2 The ’ABT863 devices are 9-bit transceivers designed for asynchronous communication between data buses. The control-function implementation allows for maximum flexibility in timing. These devices allow noninverted data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic levels at the output-enable (OEAB and OEBA) inputs. 4 3 2 1 28 27 26 A3 5 25 B3 A4 6 24 B4 A5 7 21 B5 NC 8 22 NC A6 9 21 B6 A7 10 20 B7 A8 11 19 B8 12 13 14 15 16 17 18 A9 OEBA2 GND NC OEAB1 OEAB2 B9 The outputs are in the high-impedance.
