Product details

Single comparator in a 5-pin SOT-23

The Texas Instruments TL331BIDBVR is a single general-purpose comparator with an open-collector output stage. It operates from a single or dual supply spanning 3 V to 36 V. The -40°C to 125°C operating range covers the full industrial temperature envelope. The SOT-23-5 footprint fits tight PCB layouts.

430 µA quiescent — moderate, not micropower

Maximum quiescent current is 430 µA. The input bias current is 0.025 µA max at 5 V.

Open-collector output — wired-OR and level translation

The open-collector output can sink 18 mA at 5 V (typical). The pull-up voltage can be different from the comparator supply.

Input offset — 2.5 mV max at 36 V

Maximum input offset voltage is 2.5 mV at 36 V supply.

Frequently asked questions

Can TL331BIDBVR replace LM393?

The TL331BIDBVR is a single comparator; the LM393 is a dual. Functionally both are open-collector comparators with similar supply range and propagation delay, but the TL331BIDBVR is a single-element device in a 5-pin SOT-23 package. It replaces one channel of an LM393 only if the board layout accommodates the smaller footprint and you do not need the second channel.

Is TL331BIDBVR lead-free?

Yes, the TL331BIDBVR is ROHS3 compliant, meaning it meets the Restriction of Hazardous Substances directive including lead-free requirements.
