The LM339B and LM2901B devices are the next generation versions of the industry-standard LM339 and LM2901 comparator family. These next generation B-version comparators feature lower offset voltage, higher supply voltage capability, lower supply current, lower input bias current, lower propagation delay, and improved 2 kV ESD performance and input ruggedness through dedicated ESD clamps. The LM339B and LM2901B can drop-in replace the LM239, LM339 and LM2901, for both "A" and "V" grades. All devices consist of four independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Quiescent current is independent of the supply voltage.

• NEW LM339B and LM2901B • Improved specifications of B-version – Maximum rating: up to 38V – ESD rating (HBM): 2kV – Low input offset: 0.37mV – Low input bias current: 3.5nA – Low supply-current: 200µA per comparator – Faster response time of 1µsec – Extended temperature range for LM339B • B-version is drop-in replacement for LM239, LM339 and LM2901, A and V versions • Common-mode input voltage range includes ground • Differential input voltage range equal to maximumrated supply voltage: ±38V • Low output saturation voltage • Output compatible with TTL, MOS, and CMOS • For single version, see the TL331B • For dual version, see the LM393B or LM2903B
