MXL83111E-ADA-R

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

MXL83111E-ADA-R 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: RO is high when RE is low and A-B is at or above -50mV, and low when A-B is at or below -200mV.
2 RE input Receiver output enable: RO is enabled when RE is low and goes high impedance when RE is high; RE is a hot-swap input and must be high with DE low to enter shutdown mode.
3 DE input Driver output enable: the driver outputs are enabled when DE is high and high impedance when DE is low; DE is a hot-swap input and must be low with RE high to enter shutdown mode.
4 DI input Driver input: with DE high, a low on DI forces the noninverting output low and the inverting output high, and a high on DI forces the noninverting output high and the inverting output low.
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 VCC, to be bypassed to GND with a 0.1μF capacitor; the device operates from a 3V to 5.5V supply.
