Although the logic voltage levels are very close (High: 0.7V, Low: 0.2V), I2L has high noise immunity because it operates by current instead of voltage.
Walaupun tegangan logikanya sangat dekat (Tinggi: 0.7V, Rendah: 0.2V), I2L mempunyai kekebalan desah yang tinggi karena beroperasi berdasarkan arus, bukannya tegangan.
