Outputs can be configured as DTL, TTL, open-collector, open-emitter, or RTL — this flexibility lets the same part interface directly with logic families from 5V TTL to ±15V analog rails without external level translation. Supply range spans 5V to 36V single supply or ±2.5V to ±18V dual supplies, covering common industrial and test-equipment rails. ## Input precision and speed for threshold detection Maximum input offset voltage is 1mV at ±15V — tight enough to resolve millivolt-level thresholds without external trimming in most comparator circuits. Maximum input bias current is 0.5µA at ±15V, which keeps the voltage error across source impedance below 0.5mV with a 1kΩ source — negligible for general-purpose threshold sensing. Quiescent current draws 12.5mA max per device, a reasonable budget for a dual high-speed comparator running from ±15V rails. ## Package, temperature grade, and lifecycle Housed in a 14-SOIC surface-mount package (0.154\", 3.90mm width), the LM319AM fits standard SOIC-14 footprints and is supplied in tube packaging. Rated for commercial temperature range 0°C to 70°C, suitable for benchtop instruments, telecom line cards, and industrial control boards within conditioned environments.","metaTitle":"Texas Instruments LM319AM Dual High-Speed Comparator","metaDescription":"Active dual high-speed comparator from TI in 14-SOIC. 1mV max offset, 0.5µA bias, wide supply 5-36V.
