MAX13487EESA+T-JSM from JSMSEMI, 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: RO is high if A-B ≥ -50mV and low if A-B ≤ -200mV when the receiver is enabled. |
| 2 | /RE | input | Receiver output enable, active low: RO is enabled when /RE is low, and when /RE is high the auto-direction control circuit controls the receiver; /RE is a hot-swap input. |
| 3 | /SHDN | input | Shutdown enable: device operates normally when /SHDN is high and enters low-power shutdown mode when /SHDN is low. |
| 4 | DI | input | Driver input: low forces the non-inverting output low and inverting output high, high forces the reverse; DI also feeds the internal state machine that controls driver enable, and is a hot-swap input. |
| 5 | GND | power_in | Ground. |
| 6 | A | bidirectional | Non-inverting receiver input and non-inverting driver output. |
| 7 | B | bidirectional | Inverting receiver input and inverting driver output. |
| 8 | VCC | power_in | Positive supply, 4.5V ≤ VCC ≤ 5.5V, with a 0.1µF capacitor connected between VCC and GND. |
