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 Rated for the commercial temperature range of 0°C to 70°C, this part is intended for indoor, non-condensing environments such as office equipment, appliances, and benchtop instrumentation. 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. With a 20mA typical sink capability, it can drive a small relay coil or an optocoupler LED directly, though the designer should verify the load current against the absolute maximum rating in the datasheet. The output stage also simplifies level shifting to 5V or 3.3V logic by choosing the pull-up voltage accordingly. ## Lifecycle and sourcing — active, no LTB risk The TLV1391CDBVR carries an Active product status with ROHS3 compliance.","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.
