TL331
- NEW TL331B and TL391B
- Improved specifications of B-version
- Maximum rating: up to 38 V
- ESD rating (HBM): 2k V
- Improved reverse voltage performance
- Low input offset: 0.37 mV
- Low input bias current: 3.5 nA
- Low supply-current: 430 µA
- Faster response time of 1 µsec
- TL391B provides an alternate pinout
- TL331B is improved drop-in replacement for TL331
- Common-mode input voltage range includes ground
- Differential input voltage range equal to maximum-rated supply voltage: ±38 V
- Low output saturation voltage
- Output compatible with TTL, MOS, and CMOS
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 2 V to 36 V, and VCC is at least 1.5 V 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.
