Hot-selling and scarce TL331IDBVR Single Differential Comparator SOT23-5 spot stock

Product Descriptions

The TL331B and TL391B devices are the next  generation versions of the industry-standard TL331  comparator. These next generation devices provide  outstanding value for cost-sensitive applications,  with features including lower offset voltage, higher  supply voltage capability, lower supply current,  lower input bias current, lower propagation delay,  wider temperature range and improved 2kV ESD  performance with drop-in replacement convenience.  The TL331B is a drop-in improved replacement for  both the TL331I and TL331K versions, while the  TL391B provides an alternate pinout of the TL331B  to replace competitive devices.

Operation from dual supplies also is possible as long  as the difference between the two supplies is within  2V to 36V, and VCC is at least 1.5V more positive  than the input common-mode voltage. Current drain  is independent of the supply voltage. The outputs  can be connected to other open-collector outputs to  achieve wired-AND relationships.​
