This makes it useful for sampled-data comparators, zero-crossing detectors, and any application where the comparison result must be held stable for a subsequent read cycle — think multiplexed ADC inputs or event-triggered interrupts in industrial control logic. It delivers a TTL-compatible output, so it interfaces directly with 5V logic families without a level translator. The supply range covers both single-supply rails from 4.75V to 10.5V and dual supplies from ±2.375V to ±5.75V, giving flexibility for legacy ±5V analog front ends or modern single-rail designs. Rated for the industrial temperature range of -40°C to 85°C, this comparator is at home in outdoor telecom cabinets, factory-floor sensor interfaces, and under-hood automotive modules where the ambient can swing well past room temperature. ## Supply voltage and quiescent current — sizing the rail budget The MAX9203ESA+ operates from a single supply as low as 4.75V up to 10.5V, or from dual supplies as low as ±2.375V up to ±5.75V. That means it can run on a standard 5V rail with margin for ripple, or on a ±5V supply from a split-rail converter. The quiescent current is specified at a maximum of 2mA, 1.6mA, or 800µA depending on the operating condition — the 800µA figure likely applies at the lower supply end, which matters for battery-powered or current-loop-powered designs where every microamp counts. ## Package and footprint — board-level fit Housed in an 8-pin SOIC package (0.154\" body width, 3.90mm width), the MAX9203ESA+ uses a standard surface-mount footprint that matches countless existing layouts. The supplier device package is 8-SOIC, and the mounting type is surface mount — no through-hole variant exists for this order code. Tube shipping is standard, so plan for tube-to-reel transfer if your pick-and-place line expects tape. ## Lifecycle and compliance — planning for the long haul It is also ROHS3 compliant, which means it meets the latest EU restriction-of-hazardous-substances directive — no exemption-based paperwork needed for EU-market builds.","metaTitle":"MAX9203ESA+ Comparator with Latch, 8-SOIC, Active","metaDescription":"MAX9203ESA+ single comparator with latch, TTL output, 4.75V-10.5V supply, -40°C to 85°C, 8-SOIC.

The SOIC is easier to hand-solder and inspect; the SOT-23-8 saves board area for high-density designs.
