ADM3061EARZ-R7

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

ADM3061EARZ-R7 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 is high when (A − B) ≥ −30 mV and low when (A − B) ≤ −200 mV, and is tristated when the receiver is disabled by driving RE high.
2 RE input Active-low receiver enable input: driving it low enables the receiver and driving it high disables the receiver.
3 DE input Driver enable input: a high level enables the driver differential outputs A and B, and a low level places the driver output into a high impedance state.
4 DI input Transmit data input: data to be transmitted by the driver is applied to this pin.
5 GND power_in Ground connection for the device.
6 A bidirectional Noninverting driver output and receiver input; when the driver is disabled or VCC is powered down, this pin is put into a high impedance state to avoid overloading the bus.
7 B bidirectional Inverting driver output and receiver input; when the driver is disabled or VCC is powered down, this pin is put into a high impedance state to avoid overloading the bus.
8 VCC power_in Power supply of 3.0 V to 5.5 V; adding a 0.1 µF decoupling capacitor between VCC and GND is recommended.
