Product details
Overview
MAX9075EXK from Maxim Integrated is a single-channel, rail-to-rail output comparator optimized for ultra-low-power portable systems. It delivers 580ns propagation delay at just 3µA supply current, operates from 2.1V to 5.5V single supply, features ground-sensing inputs (–0.2V to VCC – 1.2V), and drives 2mA loads with rail-to-rail swing - ideal for battery-powered threshold detection in IR receivers and keyless entry systems.
For engineers reviewing the MAX9075EXK datasheet, MAX9075EXK pinout, MAX9075EXK application, or MAX9075EXK equivalent, this page provides verified technical context, package-specific pin mapping, real-world use cases, and validated alternative comparators for low-voltage, sub-4µA design constraints.
Technical Context
The MAX9075EXK employs BiCMOS process technology to achieve stable 3µA quiescent current across –40°C to +85°C while maintaining 580ns propagation delay (tPD+/tPD−) under 100mV overdrive. Its input stage lacks differential clamping, enabling rail-to-rail differential input voltage tolerance and no phase inversion during overdrive.
The push-pull output stage supports rail-to-rail swing into 2mA loads, with VOL ≤ 0.4V and VOH ≥ VCC – 0.4V at 2mA sink/source. Input offset voltage is ±1mV (max), CMRR is 60dB (min), and PSRR is 54dB (min) - all specified over full temperature range and supply voltage (2.1V–5.5V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 3µA per comparator - enables multi-year battery life in always-on sensor nodes. |
| Propagation Delay | 580ns - supports fast edge detection in digital line receivers up to ~1MHz. |
| Supply Voltage Range | 2.1V to 5.5V - compatible with Li-ion, coin-cell, and 3.3V/5V logic rails without level shifting. |
| Input Common-Mode Range | –0.2V to VCC – 1.2V - allows direct sensing of signals referenced to ground or near-rail voltages. |
| Output Drive | Rail-to-rail swing into 2mA load - directly interfaces TTL/CMOS logic without external pull-ups. |
| Input Offset Voltage | ±1mV (max) - ensures accurate threshold detection down to sub-10mV hysteresis windows. |
| Input Bias Current | –5nA (typ) - minimizes loading error on high-impedance reference dividers. |
Pinout & Package
The MAX9075EXK is housed in a 5-pin SC70 package (outline 21-0076), footprint code 90-0188, measuring 2.0mm × 1.25mm × 0.95mm - suitable for space-constrained wearables and IoT sensors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - GND | Ground reference | Primary return path for supply and signal currents; must be low-impedance for noise immunity. |
| 2 - IN− | Inverting input | Differential input node with no internal clamp; accepts voltages down to –0.2V relative to GND. |
| 3 - IN+ | Noninverting input | Differential input node supporting common-mode range up to VCC – 1.2V. |
| 4 - OUT | Comparator output | Push-pull, rail-to-rail output capable of sourcing/sinking 2mA; no external pull-up required. |
| 5 - VCC | Positive supply | Single supply input (2.1V–5.5V); bypass with 10nF capacitor close to pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| No output phase inversion on overdrive | Ensures deterministic output state even when inputs exceed common-mode limits - critical for robust fault-tolerant sensing. |
| Rail-to-rail output swing | Delivers full logic-level compatibility with 3.3V/5V CMOS and TTL without external components. |
| Ground-sensing inputs | Accepts input signals down to –0.2V, enabling direct interface with transducer outputs referenced to system ground. |
| Ultra-small SC70 footprint | 2.0mm × 1.25mm body size reduces PCB area by >40% vs. SOT23-5 - ideal for miniaturized end equipment. |
| Low dynamic supply-current surge | Internal shoot-through current limiting maintains 3µA average current during repeated transitions - preserves battery runtime. |
Applications
| IR Receiver Front-End | Keyless Entry Sensor Interface |
|---|---|
|
Use Scenario: Demodulating 38kHz carrier pulses from IR remote signals in automotive or home security remotes. IC Role / Device Role / Timing Role: Comparator acting as zero-crossing detector with hysteresis to reject ambient light noise and recover clean digital pulses.

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3691IDCKR | Higher supply current (600nA typ), slower propagation delay (1.5µs), same SC70-5 package. | Optimized for precision over speed; better VOS (±0.5mV) but unsuitable for >500kHz edge rates. | Select TLV3691IDCKR only when ultra-low offset dominates timing requirements and 3µA budget is not binding. |
| MAX9060EXK+T | Same 3µA current and SC70-5 package, but 1.2µs propagation delay and narrower supply range (2.5V–5.5V). | Designed for cost-sensitive, non-critical timing applications; lacks rail-to-rail output swing (VOL = 0.8V @ 2mA). | Choose MAX9060EXK+T only if propagation delay >1µs is acceptable and VCC ≥ 2.5V is guaranteed. |
Compared with TLV3691IDCKR and MAX9060EXK+T, the MAX9075EXK uniquely balances sub-µs speed, true rail-to-rail output, and 3µA consumption in SC70 - making it the only option for battery-powered systems requiring both fast response and minimal quiescent power.

FAQ
What is the maximum operating temperature range for the MAX9075EXK?
The MAX9075EXK is rated for operation from –40°C to +85°C, with full electrical specifications guaranteed across this range. Its BiCMOS process ensures stable 3µA supply current and 580ns propagation delay performance at both extremes - confirmed by 100% production testing at +25°C and design validation across the full industrial temperature span.
Does the MAX9075EXK require external pull-up resistors on its output?
No, the MAX9075EXK does not require external pull-up resistors. Its push-pull output stage delivers rail-to-rail swing while sourcing and sinking up to 2mA, enabling direct interface with TTL/CMOS logic. This eliminates external components and reduces board area - a key advantage over open-drain comparators like the LMV331.
Can the MAX9075EXK operate from a 2.1V supply and still meet its 580ns propagation delay specification?
Yes, the MAX9075EXK maintains its 580ns propagation delay (tPD+/tPD−) at 2.1V supply, as verified in the Electrical Characteristics table and Typical Operating Characteristics plots (Figures toc16–toc18). Performance remains within spec across the full 2.1V–5.5V range, making it suitable for single-cell Li-ion and alkaline battery systems.
What is the input common-mode voltage range of the MAX9075EXK, and why does it matter for ground-referenced sensors?
The MAX9075EXK supports an input common-mode range from –0.2V to VCC – 1.2V. This ground-sensing capability allows direct connection of transducer outputs (e.g., thermistor dividers or photodiode amps) referenced to system ground - eliminating level-shifting circuitry and reducing error sources in low-voltage portable designs.
Is the MAX9075EXK pin-compatible with other comparators in the MAX907x family?
No, the MAX9075EXK is not pin-compatible with dual comparators like the MAX9077EKA+T. While both share the same SC70-5 footprint for the MAX9075 variants, the MAX9075EXK has five pins (GND, IN−, IN+, OUT, VCC), whereas MAX9077 devices use 8-pin packages. Pin compatibility exists only between MAX9075EXK and MAX9075EUK+T (SOT23-5), differing only in package outline and marking.
