Outputs are open-collector, CMOS, MOS, or TTL compatible — pull them up to whatever logic voltage the downstream gate needs. Input offset voltage is 2 mV max at 30V, and input bias current stays under 0.1 µA at 5V, so high-impedance sensor signals do not load down. Quiescent current maxes at 2 mA for all four channels — negligible in a battery-backed system. ## Package and footprint 14-SOIC (0.154\", 3.90 mm width) — a standard surface-mount footprint shared with many quad op-amps and comparators. The supplier device package is 14-SOIC, and it ships in Tape & Reel (TR) or Cut Tape (CT). No exotic land pattern; fits a standard SOIC-14 layout.","metaTitle":"TI LM139ADR Quad Differential Comparator, -55°C to 125°C","metaDescription":"LM139ADR quad differential voltage comparator from Texas Instruments.
