ADM3485EARZ-REEL

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

ADM3485EARZ-REEL 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 RO output Receiver output: when the receiver is enabled, RO is high if A is more than 200 mV above B and low if A is more than 200 mV below B.
2 RE input Receiver output enable: RE low enables RO, RE high puts RO in a high-impedance state, and RE high with DE low puts the device into shutdown.
3 DE input Driver output enable: a high level enables the driver differential outputs A and B, and a low level places them in a high-impedance state.
4 DI input Driver input: when the driver is enabled, a logic low on DI forces A low and B high, and a logic high on DI forces A high and B low.
5 GND power_in Ground connection, 0 V.
6 A bidirectional Noninverting receiver input A and driver output A, which sit on the RS-485 bus with a common-mode range of -7 V to +12 V.
7 B bidirectional Inverting receiver input B and driver output B, which sit on the RS-485 bus with a common-mode range of -7 V to +12 V.
8 VCC power_in Power supply, 3.3 V ± 0.3 V (VCC range 3.0 V to 3.6 V per the power supply specification).
