SN74ALS641A, SN74ALS642A, SN74AS641 OCTAL BUS TRANSCEIVERS WITH OPENĆCOLLECTOR OUTPUTS SDAS300 − MARCH 1995 DW OR N PACKAGE (TOP VIEW) DIR 1 A1 2 A2 3 A3 4 A4 5 A5 6 A6 7 A7 8 A8 9 GND 10 20 VCC 19 OE 18 B1 17 B2 16 B3 15 B4 14 B5 13 B6 12 B7 11 B8 These octal bus transceivers are designed for asynchronous two-way munication between data buses.
These 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 disables the device so that the buses are effectively isolated.
