ISO35MDWR

Texas Instruments · Isolated RS-485/422 Transceivers · SOIC-16-300mil

ISO35MDWR from Texas Instruments, in a SOIC-16-300mil. 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 VCC1 power_in Logic side power supply pin for side 1 of the isolator.
2 GND1 power_in Logic side ground, internally connected to pins 7 and 8.
3 R output Receiver output.
4 RE input Receiver logic-low enable input.
5 DE input Driver logic-high enable input.
6 D input Driver input.
7 GND1 power_in Logic side ground, internally connected to pins 2 and 8.
8 GND1 power_in Logic side ground, internally connected to pins 2 and 7.
9 GND2 power_in Bus side ground, internally connected to pins 10 and 15.
10 GND2 power_in Bus side ground, internally connected to pins 9 and 15.
11 Y output Noninverting bus output (ISO35x only; this pin is NC on the ISO15x).
12 Z output Inverting bus output (ISO35x only; this pin is NC on the ISO15x).
13 B input Inverting bus input on the ISO35x, which is an input only, not a driver output.
14 A input Noninverting bus input on the ISO35x, which is an input only, not a driver output.
15 GND2 power_in Bus side ground, internally connected to pins 9 and 10.
16 VCC2 power_in Bus side power supply pin for side 2 of the isolator.
