Table 1. SP3486 Truth Table
Pin 8 — GND — Digital Ground.
Pin 13 — DO₄B — Driver 4 output B.
Pin 14 — DO₄A — Driver 4 output A.
Pin 15 — DI₄ — Driver 4 Input — If Driver 4
output is enabled, logic 0 on DI₄ forces driver
output DO A low and DO B high. A logic 1 on DI
4

4
with Driver 4 output enabled forces driver DO₄A
high and DO B low.

SP3487 PINOUT
Pin 1 — DI₁ — Driver 1 Input — If Driver 1 output
is enabled, logic 0 on DI₁ forces driver output
DO₁A low and DO₁B high. A logic 1 on DI₁ with
Driver 1 output enabled forces driver DO A high
1
and DO B low.

Pin 2 — DO A — Driver 1 output A.
1
Pin 3 — DO₁B — Driver 1 output B.
Pin 4 — EN₁/EN₂ — Driver 1 and 2 Output
Enable. Please refer to SP3487 Truth Table (2).
Pin 9 — DI₃ — Driver 3 Input — If Driver 3 output
is enabled, logic 0 on DI₃ forces driver output
DO₃A low and DO₃B high. A logic 1 on DI₃ with
Driver 3 output enabled forces driver DO₃A high
and DO₃B low.
Pin 10 — DO₃A — Driver 3 output A.
Pin 11 — DO₃B — Driver 3 output B.
Pin 12 — EN /EN — Driver 3 and 4 Output

Pin 13 — DO₄B — Driver 4 output B.
Pin 14 — DO₄A — Driver 4 output A.
Pin 15 — DI₄ — Driver 4 Input — If Driver 4
output is enabled, logic 0 on DI₄ forces driver
output DO₄A low and DO₄B high. A logic 1 on DI₄
with Driver 4 output enabled forces driver DO₄A
high and DO₄B low.

Pin 5 — DO₂B — Driver 2 output B.
Pin 6 — DO₂A — Driver 2 output A.
Pin 7 — DI₂ — Driver 2 Input — If Driver 2 output
is enabled, logic 0 on DI forces driver output
2
DO A low and DO B high. A logic 1 on DI with
