Its 1.3µA maximum quiescent current makes it a natural fit for battery-powered monitors, portable instrumentation, and always-on sensor wake-up chains where every microamp matters. The push-pull CMOS output eliminates the need for an external pull-up resistor, further simplifying the layout. The device operates from a single supply between 1.8V and 5.5V. Built-in 4mV hysteresis provides clean switching in noisy environments. The -40°C to 85°C temperature range suits industrial control and outdoor telecom applications. ## What the Key Ratings Mean for Your BOM The 1.3µA quiescent current is the headline number for battery-life calculations. The 22µs typical propagation delay is adequate for DC and low-frequency threshold detection. The 4mV hysteresis prevents chatter at the trip point, a common failure mode when a comparator sees a slowly ramping signal. The push-pull output can source or sink 50mA typical, enough to drive a small relay coil or an optocoupler LED directly. Input bias current is a negligible 0.001µA at 5V, so high-impedance sensor dividers won't see loading errors. ## Package, Marking, and Provenance The MAX917EUK comes in a 5-pin SOT-23-5 surface-mount package. The small footprint fits dense two-layer boards. The laser-etched top mark should read the Maxim logo, date-code, and lot trace code. ## Lifecycle and Sourcing Reality RoHS compliance is not claimed on this variant — the listing notes RoHS non-compliant status, so designs requiring RoHS compliance should verify the manufacturer's latest material declaration or consider the RoHS-compliant MAX917EUK+ suffix variant.","metaTitle":"MAX917EUK Comparator with Voltage Reference, 1.3µA, SOT-23-5","metaDescription":"MAX917EUK single comparator with on-chip voltage reference. 1.3µA quiescent, 4mV hysteresis, push-pull output.
