MAX3486ECSA+T

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

MAX3486ECSA+T from Analog Devices Inc 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 goes high when A is more than 200mV above B and goes low when A is more than 200mV below B, and it is high impedance when RE is high.
2 RE input Receiver output enable: RO is enabled when RE is low and high impedance when RE is high, and RE high with DE low puts the device into low-power shutdown.
3 DE input Driver output enable: the driver outputs are enabled when DE is high and high impedance when DE is low, and DE low with RE high puts the device into low-power shutdown.
4 DI input Driver input: a low on DI forces output Y low and Z high, and a high on DI forces Y high and Z 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: 3.0V ≤ VCC ≤ 3.6V; do not operate the device with VCC > 3.6V.
