Analog Devices · RS-485/RS-422 ICs · SO-8
LTC2862IS8-2#PBF from Analog Devices, in a SO-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, high when A-B > 200mV and low when A-B < -200mV with RE low; high if inputs are open, shorted or terminated without a signal; high-impedance when RE is high. |
| 2 | RE | input | Receiver enable: low enables the receiver, high forces RO high-impedance, and RE high with DE low enters low power shutdown. |
| 3 | DE | input | Driver enable: high enables the driver, low forces the driver outputs high-impedance, and DE low with RE high enters low power shutdown. |
| 4 | DI | input | Driver input: with DE high, low drives noninverting output A low and inverting output B high, and high drives A high and B low. |
| 5 | GND | power_in | Ground. |
| 6 | A | bidirectional | Noninverting receiver input and noninverting driver output, with impedance >96kΩ in receive mode or unpowered and ±60V fault protection. |
| 7 | B | bidirectional | Inverting receiver input and inverting driver output, with impedance >96kΩ in receive mode or unpowered and ±60V fault protection. |
| 8 | VCC | power_in | Power supply, 3V < VCC < 5.5V, bypass with 0.1µF ceramic capacitor to GND. |
