General Description

SDAS226A – DECEMBER 1982 – REVISED JANUARY 1995 DW OR N PACKAGE (TOP VIEW) OEAB 1 A1 2 A2 3 A3 4 A4 5 A5 6 A6 7 A7 8 A8 9 GND 10 20 VCC 19 OEBA 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.

The control-function implementation allows for maximum flexibility in timing.

These devices allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending upon the logic levels at the output-enable (OEAB and OEBA) inputs.
