ADM2484EBRWZ-REEL7

Analog Devices · Isolated RS-485/422 Transceivers · SOIC-16-300mil

ADM2484EBRWZ-REEL7 from Analog Devices, in a SOIC-16-300mil. 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 VDD1 power_in Power supply, logic side (3.3 V or 5 V). Decoupling capacitor to GND1 required; value should be between 0.01 µF and 0.1 µF.
2 GND1 power_in Ground return for the logic side of the isolation barrier.
3 RxD output Receiver data output on the logic side. Reflects the state of the differential A/B bus inputs when the receiver is enabled.
4 RE input Receiver enable input, active low. When low, the receiver is enabled; when high, the receiver output (RxD) is high-impedance (disabled).
5 DE input Driver enable input, active high. When high, the differential driver (Y, Z outputs) is enabled; when low, the driver outputs are high-impedance.
6 TxD input Transmit data logic input to the driver. Logic level referenced to VDD1/GND1.
7 NC unconnected No connect. This pin must be left floating.
8 GND1 power_in Ground return for the logic side of the isolation barrier (second GND1 pin).
9 GND2 power_in Ground return for the isolated bus side of the isolation barrier.
10 NC unconnected No connect. This pin must be left floating.
11 Y output RS-485/RS-422 driver noninverting output. In half-duplex operation, tie externally to receiver input A (pin 14).
12 Z output RS-485/RS-422 driver inverting output. In half-duplex operation, tie externally to receiver input B (pin 13).
13 B input RS-485/RS-422 receiver inverting differential input. Line input resistance typ 96 kΩ; true fail-safe biased.
14 A input RS-485/RS-422 receiver noninverting differential input. Line input resistance typ 96 kΩ; true fail-safe biased.
15 GND2 power_in Ground return for the isolated bus side (second GND2 pin).
16 VDD2 power_in Power supply, bus side (isolated 3.3 V). Decoupling capacitor to GND2 required; value should be between 0.01 µF and 0.1 µF.
