ISO7240CDWR

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

ISO7240CDWR 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 Primary side power supply input; operates from 3.15V to 5.5V
2 GND1 power_in Ground reference for primary side
3 INA input Input channel A from primary side
4 INB input Input channel B from primary side
5 INC input Input channel C from primary side
6 IND input Input channel D from primary side
7 NC unconnected No connection pin; not connected internally
8 GND1 power_in Ground reference for primary side
9 GND2 power_in Ground reference for secondary side
10 EN input Output enable control; high or open enables all outputs; low forces outputs to high-impedance
11 OUTD tri_state Output channel D to secondary side; tri-state controlled by EN pin
12 OUTC tri_state Output channel C to secondary side; tri-state controlled by EN pin
13 OUTB tri_state Output channel B to secondary side; tri-state controlled by EN pin
14 OUTA tri_state Output channel A to secondary side; tri-state controlled by EN pin
15 GND2 power_in Ground reference for secondary side
16 VCC2 power_in Secondary side power supply input; operates from 3.15V to 5.5V
