LTC2863IS8-1#TRPBF

Analog Devices · RS-485/RS-422 ICs · SOIC-8

LTC2863IS8-1#TRPBF from Analog Devices, in a SOIC-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 VCC power_in Power supply; operate between 3V and 5.5V (3V < VCC < 5.5V) and bypass with a 0.1µF ceramic capacitor to GND.
2 RO output Receiver output goes high when A-B > 200mV, low when A-B < -200mV, and high if the receiver inputs are open, shorted, or terminated without a signal.
3 DI input Driver input: when the driver outputs are enabled, a low on DI forces Y low and Z high, and a high on DI forces Y high and Z low.
4 GND power_in Ground.
5 Y output Noninverting driver output; high-impedance when the driver is disabled or unpowered.
6 Z output Inverting driver output; high-impedance when the driver is disabled or unpowered.
7 B input Inverting receiver input; impedance is > 96kΩ in receive mode or when unpowered.
8 A input Noninverting receiver input; impedance is > 96kΩ in receive mode or when unpowered.
