COS13488EESA

COSINE · RS-485 / RS-422 ICs · SOP-8

COS13488EESA 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), RO goes high if A > B by 200mV and low if A < B by 200mV.
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: driving SHDN low puts the device in shutdown mode, and driving it high lets the device operate normally.
4 DI input Driver input: DI low forces the non-inverting output low and the inverting output high, DI 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 reference for the device.
6 A bidirectional Non-inverting receiver input and non-inverting driver output on the RS-485 bus; bus common-mode input range is -7V to 12V.
7 B bidirectional Inverting receiver input and inverting driver output on the RS-485 bus; bus common-mode input range is -7V to 12V.
8 VCC power_in Power supply, 3-V to 5.5-V; bypass VCC to GND with a 0.1µF capacitor.
