SP487 PINOUT
Pin 1 — DI
1 — Driver 1 Input — If Driver 1 output is
enabled,logic0onDI
1 forces driver output DO1A low
and DO
1B high. A logic 1 on DI1 with Driver 1 output
enabled forces driver DO
1A high and DO1B low.
Pin 2 — DO
1A — Driver 1 output A.
Pin 3 — DO
1B — Driver 1 output B.
Pin 4 — EN
1/EN2 — Driver 1 and 2 Output Enable.
Please refer to SP487 Truth Table (2).
Pin 5 — DO
2B — Driver 2 output B.
Pin 6 — DO
2A — Driver 2 output A.
Pin 7 — DI
2 — Driver 2 Input — If Driver 2 output is
enabled,logic0onDI
2 forces driver output DO2A low
and DO
2B high. A logic 1 on DI2 with Driver 2 output
enabled forces driver DO
2A high and DO2B low.
Pin 8 — GND — Digital Ground.
Pin 9 — DI
3 — Driver 3 Input — If Driver 3 output is
enabled,logic0onDI
3 forces driver output DO3A low
and DO
3B high. A logic 1 on DI3 with Driver 3 output
enabled forces driver DO
3A high and DO3B low.
Pin 10 — DO
3A — Driver 3 output A.

FEATURES…
The SP486 and SP487 are low–power quad differ-
ential line drivers meeting RS-485 and RS-422
standards. The SP486 features active high and
active low common driver enable controls; the
SP487 provides independent, active high driver
enable controls for each pair of drivers. The driver
outputs are short–circuit limited to 200mA. Data
rates up to 10Mbps are supported. Both are avail-
able in 16–pin plastic DIP and SOIC packages.
