LTC1480CS8#TRPBF

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

LTC1480CS8#TRPBF 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, three-state: HIGH if A > B by 200mV and RE is LOW, LOW if A < B by 200mV, high impedance when RE is HIGH.
2 RE input Receiver output enable: LOW enables RO, HIGH forces RO into high impedance; RE HIGH with DE LOW enters 1µA shutdown.
3 DE input Driver output enable: HIGH enables driver outputs A and B, LOW forces them high impedance; with RE HIGH the part enters low power (1µA) shutdown.
4 DI input Driver input: with DE HIGH, a low forces A LOW and B HIGH, a high forces A HIGH and B LOW.
5 GND power_in Ground.
6 A bidirectional Driver output/receiver input (A), common mode range -7V to 12V.
7 B bidirectional Driver output/receiver input (B), common mode range -7V to 12V.
8 VCC power_in Positive supply, 3.0V < VCC < 3.6V.
