MAX1487ESA+T-JSM from JSMSEMI, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RO | output | Receiver output; outputs high when A−B ≥ −50 mV and low when A−B ≤ −200 mV with /RE low; goes high-impedance when /RE is high. |
| 2 | /RE | input | Receiver output enable, active low; RO is enabled when /RE is low; RO enters high-impedance state when /RE is high. |
| 3 | DE | input | Driver output enable; driver outputs are active when DE is high; driver outputs are high-impedance when DE is low; device enters low-power shutdown mode when /RE is high and DE is low. |
| 4 | DI | input | Driver input; with DE high, DI high forces B output high and A output low; DI low forces A output high and B output low. |
| 5 | GND | power_in | Ground reference, 0 V. |
| 6 | A | bidirectional | Non-inverting receiver input and non-inverting driver output; RS-485/RS-422 bus line A; receiver input voltage range ±15 kV ESD protected. |
| 7 | B | bidirectional | Inverting receiver input and inverting driver output; RS-485/RS-422 bus line B; receiver input voltage range ±15 kV ESD protected. |
| 8 | VCC | power_in | Positive supply voltage; operating range 3.0 V to 5.5 V; absolute maximum +7 V. |
