ADM3485EARZ-REEL7

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

ADM3485EARZ-REEL7 from Analog Devices, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 RO tri_state Receiver Output; high if A > B by 200 mV when enabled, low if A < B by 200 mV when enabled, high-impedance when disabled.
2 RE input Receiver Output Enable; low enables receiver output, high places it high-impedance; with RE high and DE low, device enters shutdown.
3 DE input Driver Output Enable; high level enables driver differential outputs A and B, low level places outputs high-impedance.
4 DI input Driver Input; logic low forces A low and B high, logic high forces A high and B low when driver enabled.
5 GND power_in Ground Connection, 0 V.
6 A bidirectional Noninverting Receiver Input A / Driver Output A; differential transmission line with 12 kΩ input impedance and −7 V to +12 V common-mode input range.
7 B bidirectional Inverting Receiver Input B / Driver Output B; differential transmission line with 12 kΩ input impedance and −7 V to +12 V common-mode input range.
8 VCC power_in Power Supply; operating voltage 3.3 V ± 0.3 V.
