TOSHIBA CMOS Linear Integrated Circuit Silicon MonolithicTC75S59AFE,TC75S59AFCSingle Comparator （Open-Drain Output ）The TC75S59AFE and TC75S59AFC are CMOS general-purpose single comparators. The devices can operate from a single supply voltage and are designed for a lower supply-current than conventional general-purpose bipolar comparators. The output is designed for Open-Drain Output and can supply a higher voltage than the power supply. Therefore, it is possible to pull-up the voltage to a level higher than that of the power supply. The Open-Drain Output can be wired-OR with another Open-Drain Output circuit.* Output voltage should not exceed the maximum rating.Features• Low Supply Current: I DD = 100 μA (typ.) • Single Power Supply Operation• Wide Common Mode Input Voltage Range: V SS ~V DD − 0.9 V • Open-Drain Output Circuit • Low Input Bias Current • Small PackageMarking (top view)Pin Assignment (top view)TC75S59AFE TC75S59AFETC75S59AFC TC75S59AFCTC75S59AFETC75S59AFC CSON6-P-0.45WeightSON5-P-0.50 : 0.003 g (typ.)
