Each channel delivers a 40 ns typical propagation delay, making it fast enough for high-speed threshold detection, zero-crossing circuits, and overcurrent fault monitoring in industrial control loops. The outputs are CMOS push-pull and TTL-compatible, so they drive logic inputs directly — no external pull-up resistor needed. Supply range spans 2.7 V to 5.5 V. Input offset voltage is 2 mV max at 5 V, and quiescent current per comparator is 300 µA max. Temperature grade is -40°C to 85°C, so it fits industrial environments: motor drives, PLC input cards, and outdoor telecom gear. Hysteresis of 1.5 mV is built in, which helps clean up noisy signals without external feedback resistors. ## 40 ns propagation delay — what it means for the loop 40 ns is a mid-speed comparator. It handles PWM switching frequencies in the low-MHz range comfortably, but it is not a high-speed part for RF-level zero-crossing or GHz-rate data recovery. For a motor-drive overcurrent trip or a window comparator on a sensor output, that 40 ns response is fast enough to catch a fault before the next PWM cycle. The 1.5 mV internal hysteresis reduces chatter at the switching threshold, which is useful when the input signal rides on a noisy supply rail. ## Quad layout and supply considerations The 14-SOIC footprint is standard — 0.154\" body width, 3.90 mm. Surface-mount assembly is straightforward; no special pad geometry needed. ## Lifecycle and sourcing The MAX9144ESD+ carries an Active lifecycle status and is ROHS3 compliant.","metaTitle":"MAX9144ESD+ Quad General-Purpose Comparator, 40ns, 14-SOIC","metaDescription":"MAX9144ESD+ quad comparator from Analog Devices. 40ns propagation delay, 2.7V-5.5V supply, -40°C to 85°C.
