COSMAX13488EESA
COSINE · RS-485 / RS-422 ICs · SOP-8
COSMAX13488EESA from COSINE, 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 the receiver is enabled (RE low) and A is more than 200mV above B, RO is high, and when A is more than 200mV below B, RO is low. |
| 2 | RE | input | Receiver output enable: a low enables the receiver output RO, and a high lets the auto-direction circuit control the receiver; RE is a hot-swap input. |
| 3 | SHDN | input | Shutdown: drive low to put the device in shutdown mode, and drive high for normal operation. |
| 4 | DI | input | Driver input: low forces the non-inverting output low and the inverting output high, high forces the non-inverting output high and the inverting output low, and DI is the input to the internal state machine that automatically enables and disables the driver. |
| 5 | GND | power_in | Ground. |
| 6 | A | bidirectional | Non-inverting receiver input and non-inverting driver output on the RS-485 bus. |
| 7 | B | bidirectional | Inverting receiver input and inverting driver output on the RS-485 bus. |
| 8 | VCC | power_in | Power supply, 3-V to 5.5-V; bypass VCC to GND with a 0.1µF capacitor. |
