It operates from a single or dual supply spanning 2V to 7V, drawing a maximum quiescent current of 175µA. The open-collector output can sink up to 20mA typical, making it suitable for driving logic inputs, relays, or LEDs with an external pull-up resistor. Input offset voltage is specified at 5mV max at 5V, and input bias current is 0.25µA max at 5V — both typical for a general-purpose comparator in this class. ## Supply voltage and temperature — fit for indoor designs The 2V to 7V supply range covers common 3.3V and 5V rails with margin, but the 0°C floor means it is not specified for cold-start conditions below freezing — a factor for any design that might see an unheated warehouse or outdoor deployment. ## Open-collector output — wired-OR and level translation The open-collector output lets multiple comparators share a common pull-up resistor for wired-OR logic, or interface to a higher-voltage load than the comparator's own supply. The output stage also simplifies level shifting to 5V or 3.3V logic by choosing the pull-up voltage accordingly.","metaTitle":"TLV1391CDBVR Differential Comparator, SOT-23-5, 2V to 7V","metaDescription":"TI TLV1391CDBVR single differential comparator, open collector output, 2V to 7V supply, 0°C to 70°C, SOT-23-5.
