TC75W58FU/FK TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic TC75W58FU,TC75W58FK Dual Comparator TC75W58 is a CMOS type general-purpose dual comparator capable of single power supply operation and using lower supply currents than the conventional bipolar comparators. Its open drain output forms wired OR with other open drain outputs. Features z Low supply current: IDD = 20μA (typ.) z Single power supply operation z Wide common mode input voltage range: VSS~VDD−0.9V z Open drain output circuit z Low input bias current z Small package Weight SSOP8-P-0.65: 0.021g (typ.)

Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated failure rate, etc). Note: Since this product sometimes brings about latchcap, which is peculiar to CMOS devices, note the following points: • Don’t raise the voltage level of I/O pins beyond VDD, nor lower it below VSS. Consider the timing for power supply, too. • Don’t let any abnormal noise enter the device. 2 2007-11-01 TC75W58FU/FK Electrical Characteristics (VDD = 5V, VSS = GND, Ta = 25°C) Symbol Test Circuit Test Condition Min Typ.
