SP3483EN-L

MaxLinear · RS-485 / RS-422 ICs · SOIC-8

SP3483EN-L from MaxLinear, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 RO output Receiver output. Drives logic HIGH (>= VCC-0.4V, IO=-1.5mA) when A-B > +200mV, LOW (<= 0.4V, IO=2.5mA) when A-B < -200mV. Fail-safe HIGH when receiver inputs are open. Enters high-impedance when RE is HIGH.
2 RE input Receiver Output Enable, active LOW. Logic LOW enables the receiver output (RO); logic HIGH tri-states RO. Combined with DE=LOW puts the device into shutdown mode.
3 DE input Driver Output Enable, active HIGH. Logic HIGH enables the differential driver outputs on A and B; logic LOW forces A/B into high-impedance. VIH >= 2.0V, VIL <= 0.8V, input current +/-10 uA.
4 DI input Driver data input. When DE is HIGH, DI=HIGH drives A HIGH / B LOW and DI=LOW drives A LOW / B HIGH. VIH >= 2.0V, VIL <= 0.8V, input current +/-10 uA.
5 GND power_in Ground reference for the device. Connect to system ground.
6 A bidirectional Non-inverting driver output / non-inverting receiver input on the RS-485 differential bus. Common-mode input range -7V to +12V; receiver input resistance 12 kOhm min (15 kOhm typ). Driver short-circuit current limited to +/-250 mA.
7 B bidirectional Inverting driver output / inverting receiver input on the RS-485 differential bus. Common-mode input range -7V to +12V; receiver input resistance 12 kOhm min (15 kOhm typ). Driver short-circuit current limited to +/-250 mA.
8 VCC power_in Positive supply input, 3.3V +/-5% (absolute max 6.0V). Typical supply current 800-1000 uA (no load); ~1 uA typ / 10 uA max in shutdown.
