LTC2862HS8-1#PBF

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

LTC2862HS8-1#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 signal, and high-impedance when RE is high.
2 RE input Receiver enable: a low input enables the receiver, a high input forces RO high-impedance, and RE high with DE low enters low power shutdown.
3 DE input Driver enable: a high input enables the driver, a low input forces the driver outputs high-impedance, and DE low with RE high enters low power shutdown.
4 DI input Driver input: with DE high, a low on DI forces A (noninverting output) low and B high, and a high on DI forces 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.
