SP1485EEN-L

MaxLinear · Pre-ordered Chips · SOIC-8

SP1485EEN-L from MaxLinear, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 RO output Receiver output, driven high when the A-B input is above +0.2V or the inputs are open (fail-safe) and tri-stated when RE is high.
2 RE input Receiver output enable, active LOW; a logic low enables the receiver and a logic high disables it (input high threshold 2.0V, low 0.8V).
3 DE input Driver output enable, active HIGH; a logic high enables the differential driver outputs and a logic low tri-states them.
4 DI input Driver input; a logic high on DI with the driver enabled gives A high and B low, and a logic low gives the opposite.
5 GND power_in Ground connection.
6 A bidirectional Driver output/receiver input, non-inverting, with receiver common-mode range of -7V to +12V.
7 B bidirectional Driver output/receiver input, inverting, with receiver common-mode range of -7V to +12V.
8 VCC power_in Positive supply, 4.75V to 5.25V (absolute maximum +7V).
