SP486 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 — Driver Output Enable. Please refer to
SP486 Truth Table (1).
Pin 5 — DO2B — 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.
Pin 11 — DO
3B — Driver 3 output B.
Pin 12 — EN — Driver Output Disable. Please refer
to SP486 Truth Table (1).
Pin 13 — DO
4B — Driver 4 output B.
Pin 14 — DO
4A — Driver 4 output A.
Pin 15 — DI
4 — Driver 4 Input — If Driver 4 output
is enabled, logic 0 on DI
4 forces driver output DO4A
low and DO
4B high. A logic 1 on DI4 with Driver 3
output enabled forces driver DO
4A high and DO4B
low.
