Texas Instruments · Digital Isolators · SSOP-16-150mil

ISO7740FDBQR from Texas Instruments, in a SSOP-16-150mil. 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 Power supply input for input side, rated 2.25 V to 5.5 V
2 GND1 power_in Ground return for input side
3 INA input Digital input for channel A, accepts CMOS logic levels
4 INB input Digital input for channel B, accepts CMOS logic levels
5 INC input Digital input for channel C, accepts CMOS logic levels
6 IND input Digital input for channel D, accepts CMOS logic levels
7 NC unconnected Not connected
8 GND1 power_in Ground return for input side
9 GND2 power_in Ground return for output side
10 EN2 input Output enable for side 2; high or open enables outputs, low forces high impedance
