Product details

Single differential comparator in a small SOT-23-5

Input offset voltage is specified at 5mV maximum at 5V, and input bias current maxes at 0.25µA at 5V — both typical for a general-purpose differential comparator in this class. The single-element layout means you get one comparator in a five-pin SOT-23 footprint, useful when you need exactly one threshold detector on a dense board and a dual or quad package would waste space.

Open-collector output — pull-up resistor and logic translation

The output is open collector, so it sinks current only. A pull-up resistor to the logic supply rail is required. The output can sink up to 20mA typical.

Package and footprint — SOT-23-5 for dense boards

The TLV1391IDBVT ships in the SOT-753 package, with a supplier device package of SOT-23-5. That is a five-pin SOT-23 footprint.

For BOM freeze purposes, this part can be designed in without worrying about a near-term EOL notice.

Frequently asked questions

Is TLV1391IDBVT RoHS compliant?

Yes, TLV1391IDBVT is ROHS3 compliant, meeting the current EU RoHS directive without exemptions.

What is the TLV1391IDBVT comparator used for?

The TLV1391IDBVT is a single differential comparator with an open-collector output. Typical applications include threshold detection (e.g., over-voltage or under-voltage monitoring), zero-crossing detection, level translation between different logic families, and window comparators for sensor signal conditioning in industrial and telecom environments.

Is TLV1391IDBVT equivalent to LM393?

No, the TLV1391IDBVT is not a direct equivalent to the LM393. The LM393 is a dual comparator in an 8-pin package, while the TLV1391IDBVT is a single comparator in a 5-pin SOT-23-5. Both have open-collector outputs and similar supply ranges, but the pinout and package are different. For a single comparator in a small footprint, the TLV1391IDBVT is the closer fit.

What is the difference between TLV1391 and LM393?

The primary differences are package and channel count. TLV1391IDBVT is a single comparator in a SOT-23-5 (5-pin) package. The LM393 is a dual comparator in an SOIC-8 or DIP-8 package. Both use open-collector outputs and operate from a 2V to 7V supply range. The TLV1391IDBVT draws a maximum quiescent current of 175µA per comparator, while the LM393 typically draws around 400µA per package (200µA per comparator).
