MAX3082EESA+T

Maxim Integrated · RS-485/RS-422 ICs · SOIC-8

MAX3082EESA+T from Maxim Integrated, 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 and A - B ≥ -50mV, RO is high; when A - B ≤ -200mV, RO is low.
2 RE input Receiver output enable: drive RE low to enable RO, which is high impedance when RE is high; drive RE high and DE low to enter low-power shutdown mode.
3 DE input Driver output enable: drive DE high to enable the driver outputs, which are high impedance when DE is low.
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; receiver inputs A and B are rated ±13V (absolute maximum).
7 B bidirectional Inverting receiver input and inverting driver output; receiver inputs A and B are rated ±13V (absolute maximum).
8 VCC power_in Positive supply, 4.75V ≤ VCC ≤ 5.25V.
