SP3072EMN-L

MaxLinear · Pre-ordered Chips · SOIC-8

SP3072EMN-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: when RE is low, RO is high if (A-B) ≥ -50mV and low if (A-B) ≤ -200mV.
2 RE input Receiver Output Enable: low enables RO, high makes RO high impedance; RE high with DE low enters shutdown, and RE is a hot-swap input.
3 DE input Driver Output Enable: high enables the driver outputs, low makes them high impedance; DE low with RE high enters shutdown, and DE is a hot-swap input.
4 DI input Driver Input: with DE high, a low on DI forces the noninverting output low and inverting output high, and a high on DI does the opposite.
5 GND power_in Ground.
6 A bidirectional Noninverting Receiver Input and Noninverting Driver Output.
7 B bidirectional Inverting Receiver Input and Inverting Driver Output.
8 VCC power_in Positive supply (3.3V operation); bypass VCC to GND with a 0.1µF capacitor.
