ISO1412BDWR

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

ISO1412BDWR 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.
2 GND1 power_in Ground connection for VCC1 side.
3 R output Receiver output.
4 RE input Receiver enable; pin disables receiver output when high or open, enables when low.
5 DE input Driver enable; pin enables driver output when high, disables when low or open.
6 D input Driver input.
7 NC unconnected No internal connection.
8 GND1 power_in Ground connection for VCC1 side.
9 GND2 power_in Ground connection for VCC2 side.
10 NC unconnected No internal connection.
11 Y output Driver non-inverting output.
12 Z output Driver inverting output.
13 B input Bus-side receiver inverting input.
14 A input Bus-side receiver non-inverting input.
15 GND2 power_in Ground connection for VCC2 side.
