MAX3082ESA+T

Analog Devices Inc Maxim Integrated · RS-485 / RS-422 ICs · SOP-8

MAX3082ESA+T from Analog Devices Inc Maxim Integrated, in a SOP-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.
3 DE input Driver output enable: drive DE high to enable the driver outputs, which are high impedance when DE is low; drive RE high and DE low to enter low-power shutdown.
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 threshold is -50mV to -200mV with fail-safe to logic high when inputs are open or shorted.
7 B bidirectional Inverting receiver input and inverting driver output; receiver threshold is -50mV to -200mV with fail-safe to logic high when inputs are open or shorted.
8 VCC power_in Positive supply; 4.75V ≤ VCC ≤ 5.25V.
