ISO7342CDWR

Texas Instruments · Digital Isolators · SOIC-16-300mil

ISO7342CDWR 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 Power supply for input-side isolation barrier; 3-5.5V recommended operating range
2 GND1 power_in Ground connection for input-side power supply VCC1
3 INA input Channel A input with integrated noise filter; 2-5.5V high-level, 0-0.8V low-level thresholds
4 INB input Channel B input with integrated noise filter; 2-5.5V high-level, 0-0.8V low-level thresholds
5 OUTC output Channel C output; high-level VCCO-0.5V to 5V typical, low-level 0-0.4V at 5V supply
6 OUTD output Channel D output; high-level VCCO-0.5V to 5V typical, low-level 0-0.4V at 5V supply
7 EN1 input Output enable 1 for side-1 outputs; high or disconnected enables outputs, low disables to high-impedance
8 GND1 power_in Ground connection for input-side power supply VCC1
9 GND2 power_in Ground connection for output-side power supply VCC2
10 EN2 input Output enable 2 for side-2 outputs; high or disconnected enables outputs, low disables to high-impedance
11 IND input Channel D input with integrated noise filter; 2-5.5V high-level, 0-0.8V low-level thresholds
12 INC input Channel C input with integrated noise filter; 2-5.5V high-level, 0-0.8V low-level thresholds
13 OUTB output Channel B output; high-level VCCO-0.5V to 5V typical, low-level 0-0.4V at 5V supply
14 OUTA output Channel A output; high-level VCCO-0.5V to 5V typical, low-level 0-0.4V at 5V supply
15 GND2 power_in Ground connection for output-side power supply VCC2
16 VCC2 power_in Power supply for output-side isolation barrier; 3-5.5V recommended operating range
