MAX3082CSA+T

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

MAX3082CSA+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: with RE low, RO is high if A - B ≥ -50mV and low if A - B ≤ -200mV; high impedance when RE is high.
2 RE input Receiver output enable: drive low to enable RO, high for high-impedance RO; RE high with DE low enters low-power shutdown.
3 DE input Driver output enable: drive high to enable driver outputs, low for high impedance; RE high with DE low enters low-power shutdown.
4 DI input Driver input: with DE high, a low forces the noninverting output low and inverting output high, and a high 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, 4.75V ≤ VCC ≤ 5.25V.
