ISO7730FDWR

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

ISO7730FDWR 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 Input side supply voltage with recommended operating range of 2.25V to 5.5V per Section 5.3.
2 GND1 power_in Ground connection for VCC1 input side per Table 4-1.
3 INA input Input channel A with switching threshold from 0.3×VCCI (low) to 0.7×VCCI (high) per Section 5.9.
4 INB input Input channel B with switching threshold from 0.3×VCCI (low) to 0.7×VCCI (high) per Section 5.9.
5 INC input Input channel C with switching threshold from 0.3×VCCI (low) to 0.7×VCCI (high) per Section 5.9.
6 NC unconnected Not connected; no electrical function per Table 4-1.
7 NC unconnected Not connected; no electrical function per Table 4-1.
8 GND1 power_in Ground connection for VCC1 input side per Table 4-1.
9 GND2 power_in Ground connection for VCC2 output side per Table 4-1.
10 EN2 input Output enable 2; high or open state enables side 2 outputs, low state places outputs in high impedance per Table 4-1.
