V CCL<br />
PCA9517<br />
• Isolates capacitance allowing 400pF on each side<br />
of <strong>the</strong> device<br />
• Enable/disable pin allows isolation of bus<br />
• Dual V CC s allow voltage translation with optimum<br />
noise margin on <strong>the</strong> low voltage side<br />
• Drop in replacement for <strong>the</strong> PCA9515<br />
