SP485RCN-L

MaxLinear · Pre-ordered Chips · SOIC-8

SP485RCN-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, tri-stated when RE is HIGH and driven HIGH when the inputs are open (fail-safe).
2 RE input Receiver output enable, active LOW; logic HIGH tri-states the receiver output (VIL 0.8V max, VIH 2.0V min).
3 DE input Driver output enable, active HIGH; logic LOW tri-states the driver outputs to high impedance (>100kΩ).
4 DI input Driver input (VIL 0.8V max, VIH 2.0V min).
5 GND power_in Ground connection.
6 A bidirectional Non-inverting driver output / receiver input, with common-mode range -7V to +12V and 150kΩ typical receiver input impedance.
7 B bidirectional Inverting driver output / receiver input, with common-mode range -7V to +12V and 150kΩ typical receiver input impedance.
8 VCC power_in Positive supply, 4.75V ≤ VCC ≤ 5.25V (absolute maximum +7V).
