SP486E 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
DI with Driver 1 output enabled forces driver
1
DO A high and DO B low.

Pin 2 — DO₁A — Driver 1 output A.
Pin 3 — DO B — Driver 1 output B.

Pin 4 — EN — Driver Output Enable. Please
refer to SP486E Truth Table (1).
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
2
output DO A low and DO B high. A logic 1 on

2
DI₂ with Driver 2 output enabled forces driver
DO₂A high and DO₂B low.
Pin 9 — DI — Driver 3 Input — If Driver 3
3
output is enabled, logic 0 on DI forces driver
3
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 — Driver Output Disable. Please
refer to SP486E Truth Table (1).
Pin 13 — DO₄B — Driver 4 output B.
Pin 14 — DO A — 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 3 output enabled forces driver
DO₄A high and DO₄B low.
Pin 16 — Supply Voltage V_CC — 4.75V ≤ V_CC ≤
5.25V.
