ISO1410DWR

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

ISO1410DWR from Texas Instruments, 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 VCC1 power_in Logic-side supply. Operating range 1.71 V to 5.5 V. Local bypass capacitor to GND1 required.
2 GND1 power_in Logic-side ground reference for VCC1. Pins 2 and 8 must both be tied to GND1.
3 R output Receiver output. Drives logic-level data recovered from the isolated RS-485 bus (A/B) to the MCU.
4 RE input Receiver enable, active-low. Receiver output is enabled when RE is low; disabled (high-Z on R) when RE is high or left open.
5 DE input Driver enable, active-high. Driver outputs on the bus (A/B) are enabled when DE is high; disabled when DE is low or open.
6 D input Driver input. Logic-side data to be transmitted onto the isolated RS-485 bus when DE is asserted.
7 NC unconnected No internal connection. May be tied to any supply or ground on the PCB without affecting device operation.
8 GND1 power_in Logic-side ground reference for VCC1. Both pin 2 and pin 8 must be connected to GND1.
9 GND2 power_in Bus-side ground reference for VCC2. Both pin 9 and pin 15 must be connected to GND2.
10 NC unconnected No internal connection. May be left floating or tied to PCB supply/ground without affecting operation.
11 NC unconnected No internal connection on the half-duplex ISO1410 variant. (This position is used for the Y driver output on the full-duplex ISO1412.)
12 A bidirectional Non-inverting RS-485 bus I/O. Acts as driver output when DE=1 and as receiver non-inverting input when RE=0. Absolute-max bus voltage ±18 V relative to GND2; ±16 kV IEC 61000-4-2 contact ESD rated.
13 B bidirectional Inverting RS-485 bus I/O. Acts as driver complementary output when DE=1 and as receiver inverting input when RE=0. Absolute-max bus voltage ±18 V relative to GND2; ±16 kV IEC 61000-4-2 contact ESD rated.
14 NC unconnected No internal connection on the half-duplex ISO1410 variant. (This position is used for the A input on the full-duplex ISO1412.)
15 GND2 power_in Bus-side ground reference for VCC2. Both pin 9 and pin 15 must be connected to GND2.
16 VCC2 power_in Bus-side (isolated) supply for the RS-485 transceiver. Operating range 3 V to 5.5 V. Local bypass capacitor to GND2 required.
