SP490CN-L

MaxLinear · Pre-ordered Chips · SOIC-8

SP490CN-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 VCC power_in Positive supply; operates at 5V (4.75V to 5.25V).
2 R output Receiver output, driven high when the receiver input is left unconnected (fail-safe).
3 D input Driver input, logic high above 2.0V and logic low below 0.8V.
4 GND power_in Ground connection.
5 Y output Non-inverting driver output, differential, within ±14V absolute maximum.
6 Z output Inverting driver output, differential, within ±14V absolute maximum.
7 B input Inverting receiver input, common mode range -7V to 12V with 12kΩ minimum input resistance.
8 A input Non-inverting receiver input, common mode range -7V to 12V with 12kΩ minimum input resistance.
