The supply range spans 2V to 32V single-supply or ±1V to ±16V dual-supply, making it suitable for systems with unregulated rails, battery backup, or split supplies. ## Parametric profile for BOM-fit decisions Each comparator can sink 16mA at 5V, sufficient to drive a logic input, an LED indicator, or a small relay coil through the open-collector pin. The quiescent current per device is 2.5mA max, keeping the power budget manageable in multi-channel designs. Input offset voltage is 7mV max at 5V, and input bias current is 0.25µA max at 5V — adequate for threshold detection, zero-crossing detectors, and window comparators where precision below 5mV is not required. The through-hole 14-DIP (0.300\", 7.62mm) package is easy to hand-assemble, socket, or rework, and the 0.100-inch pin pitch matches standard prototyping boards. The LM2901N/PB is officially obsolete. No direct replacement or successor is listed by Texas Instruments. For new designs, consider a quad comparator in a surface-mount package, but verify pin compatibility and supply range for your specific application.","metaTitle":"LM2901N/PB Quad General-Purpose Comparator, Obsolete, 14-DIP","metaDescription":"LM2901N/PB is a quad comparator with open-collector outputs, 2V~32V supply, -40°C~125°C range.
