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, with features including lower offset voltage, higher supply – Improved reverse voltage performance voltage capability, lower supply current, lower input – Low input offset: 0.37 mV bias current, lower propagation delay, wider – Low input bias current: 3.5 nA temperature range and improved 2kV ESD – Low supply-current: 430 µA performance with drop-in replacement convenience. – Faster response time of 1 µsec The TL331B is a drop-in improved replacement for – TL391B provides an alternate pinout both the TL331I and TL331K versions, while the • TL331B is improved drop-in replacement for TL391B provides an alternate pinout of the TL331B to TL331 replace competitive devices. • Common-mode input voltage range includes Operation from dual supplies also is possible as long ground as the difference between the two supplies is within 2 • Differential input voltage range equal to maximum- V to 36 V, and VCC is at least 1.5 V more positive rated supply voltage: ±38 V than the input common-mode voltage. Current drain is • Low output saturation voltage independent of the supply voltage. The outputs can • Output compatible with TTL, MOS, and CMOS be connected to other open-collector outputs to achieve wired-AND relationships.
