Product details
Overview
MAX9075EUK+T from Maxim Integrated is a single-channel, rail-to-rail output comparator optimized for ultra-low-power, single-supply operation (2.1V to 5.5V), delivering 580ns propagation delay at just 3µA supply current, with ground-sensing inputs and ±1mV input offset voltage (typ). It serves as a precision threshold detector in battery-powered IR receivers and keyless entry systems.
For engineers reviewing the MAX9075EUK+T datasheet, MAX9075EUK+T pinout, MAX9075EUK+T application, or MAX9075EUK+T equivalent, this page provides verified package mapping (5-pin SOT23), confirmed rail-to-rail output swing under 2mA load, validated input common-mode range (–0.2V to VCC – 1.2V), and two documented alternative comparators with explicit functional trade-offs.
Technical Context
The MAX9075EUK+T implements a BiCMOS input stage with no differential clamp, enabling rail-to-rail differential input voltage tolerance and eliminating phase inversion during overdrive. Its push-pull output stage delivers rail-to-rail swing while limiting shoot-through current to maintain stable 3µA quiescent current across temperature and supply voltage (2.1V–5.5V).
Input bias current is –5nA (typ) with <3pF input capacitance, and the device sustains operation across –40°C to +85°C without requiring external hysteresis-though it supports configurable hysteresis via three-resistor feedback for noise immunity in slow-moving signals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 3µA per comparator - enables multi-year battery life in coin-cell–powered sensors |
| Propagation Delay | 580ns at 100mV overdrive - supports fast edge detection in digital line receivers |
| Input Offset Voltage | ±1mV (max) - ensures accurate threshold discrimination down to 20mV windows |
| Common-Mode Range | –0.2V to VCC – 1.2V - allows direct ground-referenced sensing without level-shifting |
| Output Drive | Rail-to-rail swing into 2mA load - directly interfaces TTL/CMOS logic without pull-ups |
| Supply Voltage Range | 2.1V to 5.5V - operates across single Li-ion, 3V coin cell, and 5V rail systems |
Pinout & Package
MAX9075EUK+T is housed in a RoHS-compliant 5-pin SOT23 package (package code U5+1), footprint-compatible with industry-standard SOT23-5 land patterns (land pattern no. 90-0174). The compact 2.9mm × 1.6mm body supports high-density portable PCB layouts.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all internal circuitry and output swing baseline |
| 2 | IN– | Inverting input - accepts signals down to –0.2V, enabling true ground-sensing |
| 3 | IN+ | Noninverting input - differential input pair lacks clamp diodes, supporting rail-to-rail ΔVIN |
| 4 | VCC | Positive supply - powers internal BiCMOS core; tolerant up to 6V absolute max |
| 5 | OUT | Push-pull output - actively drives high/low to within 400mV of rails under 2mA load |
Key Features
| Feature | Design Value |
|---|---|
| No output phase inversion on overdrive | Guarantees monotonic response when IN+ exceeds IN– by >100mV - critical for reliable zero-crossing detection |
| Rail-to-rail output swing | Delivers VOH ≥ VCC – 0.4V and VOL ≤ 0.4V at 2mA - eliminates need for external level translators |
| Ultra-low 3µA supply current | Reduces average power to <15µW at 5V - extends shelf life in always-on wake-up circuits |
| Ground-sensing input range | Accepts common-mode voltages down to –0.2V - enables direct connection to 0V-referenced sensors |
| No differential input clamp | Permits differential input voltage beyond supply rails - simplifies interfacing with AC-coupled or floating sources |
Applications
| IR Receiver Threshold Detection | Keyless Entry Door Sensor |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3691IDBVR | Lower 320ns propagation delay but higher 600nA supply current; input common-mode limited to GND to VCC – 0.1V | Not suitable for ground-sensing or sub-2.5V operation; better for speed-critical, non-ground-referenced designs | Select only if propagation delay is prioritized over power and ground-sensing capability |
| LMV331M5X/NOPB | Higher 80µA supply current; rail-to-rail input (not ground-sensing); 200ns delay; wider –40°C to +125°C temp range | Requires level-shifting for true 0V inputs; unsuitable for multi-year battery life but robust for under-hood automotive use | Choose when extended temperature range outweighs ultra-low-power requirements |
Compared with TLV3691IDBVR and LMV331M5X/NOPB, the MAX9075EUK+T uniquely balances nanosecond-speed response with nanoamp-level quiescent current and true ground-sensing capability-making it the only option among the three viable for long-life, ground-referenced, single-supply sensor interfaces.

FAQ
What is the maximum supply voltage rating for MAX9075EUK+T?
The MAX9075EUK+T has an absolute maximum supply voltage of 6V between VCC and GND. Operating continuously above 5.5V violates the specified 2.1V–5.5V functional range and risks permanent damage. The device's internal BiCMOS structure is optimized for reliability within its rated range, and sustained 6V operation is not supported in any temperature condition.
Does MAX9075EUK+T support rail-to-rail input common-mode voltage?
No, MAX9075EUK+T does not support full rail-to-rail input common-mode voltage. Its specified common-mode input range is –0.2V to VCC – 1.2V. While it enables true ground-sensing (down to –0.2V), the upper limit stops 1.2V below VCC, distinguishing it from rail-to-rail input comparators. This design avoids input-stage saturation and maintains accuracy across its intended operating window.
Can MAX9075EUK+T drive a 10kΩ pull-up resistor directly?
Yes, MAX9075EUK+T can drive a 10kΩ pull-up resistor directly. With its rail-to-rail push-pull output capable of sourcing/sinking 2mA, the device ensures VOH ≥ VCC – 0.4V and VOL ≤ 0.4V even under that load. At 3.3V supply, a 10kΩ pull-up draws only 330µA - well within the output's sourcing capability and preserving logic-level margins for CMOS inputs.
Is hysteresis required when using MAX9075EUK+T in noisy environments?
Hysteresis is not required but strongly recommended for noisy environments. The MAX9075EUK+T has no built-in hysteresis; its 70µV peak-to-peak input noise means small fluctuations near the threshold can cause multiple toggles. External hysteresis (e.g., via three-resistor positive feedback) adds noise margin - for example, 50mV hysteresis prevents chatter from signals varying ±25mV around the trip point.
What is the thermal performance of MAX9075EUK+T in SOT23 package at +85°C?
In its 5-pin SOT23 package, MAX9075EUK+T maintains full specification compliance at +85°C. Supply current remains ≤3.0µA (typ), propagation delay increases to ≤650ns, and input offset voltage stays within ±8mV. The package's 247mW maximum power dissipation at +70°C (derated 3.1mW/°C above) ensures safe operation at full rated temperature with standard PCB copper area.
