Ordering Information

CTS7509, output A can be setup as active low with open drain only (require an external pull-up resistor);
CTS7510, output B can be setup as active low with push-pull, or active high with push-pull, or active low with open drain output (built-in internal pull-up resistor, no require an external pull-up resistor any more).
