# LM339ANSR (Component) ## Description 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 #CommonPartsLibrary #IntegratedCircuit #Comparator ## Component Details - **Owner:** lcsc - **Created:** 3/17/2026 - **Last Updated:** 6/4/2026 - **Visibility:** Public - **Manufacturer Part Number:** LM339ANSR - **LCSC Part Number:** C2870366 - **License:** https://creativecommons.org/licenses/by/4.0/ - **Package or Case Code:** SO-14_L10.2-W5.3-P1.27-LS7.8-BL-1 - **Manufacturer Name:** TI(德州仪器) - **Part Type:** Comparators - **Datasheet URL:** https://www.ti.com/lit/ds/symlink/lm139.pdf?ts=1753716937461&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FLM139 - **Symbol Style:** parametric-v1 - **Used in:** 6 projects ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
