TL331B

TL331, TL331B, TL391B SLVS238K – AUGUST 1999 – REVISED SEPTEMBER 2023 TL331B, TL391B and TL331 Single Comparators 1 Features 3 Description NEW TL331B and TL391B The TL331B and TL391B devices are the next Improved specifications of B-version generation versions of the industry-standard TL331 – Maximum rating: up to 38 V comparator. These next generation devices provide – ESD rating (HBM): 2k V outstanding value for cost-sensitive applications, – Improved reverse voltage performance with features including lower offset voltage, higher – Low input offset: 0.37 mV supply voltage capability, lower supply current, – Low input bias current: 3.5 nA lower input bias current, lower propagation delay, – Low supply-current: 430 µA wider temperature range and improved 2kV ESD – Faster response time of 1 µsec performance with drop-in replacement convenience. – TL391B provides an alternate pinout The TL331B is a drop-in improved replacement for TL331B is improved drop-in replacement for both the TL331I and TL331K versions, while the TL331 TL391B provides an alternate pinout of the TL331B Common-mode input voltage range includes to replace competitive devices. ground Differential input voltage range equal to maximum- rated supply voltage: ±38 V Low output saturation voltage Output compatible with TTL, MOS, and CMOS Operation from dual supplies also is possible as long as the difference between the two supplies is within 2 V to 36 V, and VCC is at l...
