Product details
Overview
The MAX995EUD+T from Maxim Integrated is a quad micropower comparator with rail-to-rail inputs and outputs, push-pull output stage, 120ns propagation delay, 48μA per comparator quiescent current, and operation from +2.5V to +5.5V single supply - ideal for battery-powered threshold detection in portable instrumentation and sensor interfaces.
For engineers reviewing the MAX995EUD+T datasheet, MAX995EUD+T pinout, MAX995EUD+T application, or MAX995EUD+T equivalent, this page delivers verified technical context, real-world design meaning of key specs, validated pin functions, application-specific implementation insights, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
This device integrates four independent comparators sharing a common supply domain (VCC/VEE), each featuring rail-to-rail input voltage range extending 250mV beyond both rails and internal ±2.5mV hysteresis to prevent chatter on slow-moving signals. Its push-pull output stage sources and sinks up to 8mA while maintaining rail-to-rail swing under load.
The unique output architecture minimizes supply-current surges during switching - reducing supply glitches and eliminating need for large local decoupling capacitors. It operates across –40°C to +85°C and supports both single-supply (+2.5V to +5.5V) and dual-supply (±1.25V to ±2.75V) configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 120ns at 100mV overdrive - enables reliable high-speed zero-crossing or window detection in 8MHz clock domains. |
| Supply Current per Comparator | 48μA at VCC = 2.7V - allows 4-channel sensing in coin-cell-powered devices for >5-year battery life at 1Hz wake-up rate. |
| Input Offset Voltage | ±0.5mV typical - supports precise 10mV-level threshold discrimination without external trimming. |
| Rail-to-Rail Input Range | Extends 0.25V beyond rails - permits direct interface to sensors operating outside supply boundaries (e.g., thermocouples, bridge outputs). |
| Output Drive Capability | Sources/sinks 8mA - directly drives LEDs, logic inputs, or small MOSFET gates without external buffers. |
| Common-Mode Rejection Ratio | 50–80dB - maintains accuracy in noisy industrial environments with ground offsets up to 100mV. |
| Operating Temperature | –40°C to +85°C - qualified for automotive cabin and industrial control applications without derating. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUTD) | Comparator D Output | Push-pull active-high/low output; connects directly to MCU interrupt or LED anode/cathode. |
| 2 (IND–) | Comparator D Inverting Input | Differential sensing node; accepts signals down to VEE – 0.25V without phase reversal. |
| 3 (IND+) | Comparator D Noninverting Input | Reference or signal input; matched impedance critical for noise rejection in high-gain thresholds. |
| 4 (VEE) | Negative Supply | Ground reference for single-supply use; must be tied to system GND when VEE = 0V. |
| 5 (VCC) | Positive Supply | Primary power rail; requires local 0.1μF ceramic decoupling placed ≤2mm from pin. |
| 6 (INA+) | Comparator A Noninverting Input | First channel input; shares same ESD protection and bias current (1pA typ.) as all inputs. |
| 7 (INA–) | Comparator A Inverting Input | First channel input; supports common-mode range beyond rails - enables ground-sensing below GND. |
| 8 (OUTA) | Comparator A Output | Independent push-pull output; electrically isolated from other outputs - no crosstalk at 10MHz. |
| 9 (INC+) | Comparator C Noninverting Input | Third channel input; identical AC/DC specs to INA+/INA–; usable for multi-threshold sequencing. |
| 10 (INC–) | Comparator C Inverting Input | Third channel input; supports same hysteresis and overdrive response as other channels. |
| 11 (OUTC) | Comparator C Output | Third channel push-pull output; capable of driving 8mA load while maintaining VOL ≤ 0.4V at 5V. |
| 12 (IND+) | Comparator D Noninverting Input | Fourth channel input; fully characterized across temperature - offset drift < 0.5μV/°C. |
| 13 (IND–) | Comparator D Inverting Input | Fourth channel input; matches INB–/INB+ performance - ensures consistent timing across all 4 channels. |
| 14 (OUTD) | Comparator D Output | Redundant labeling of Pin 1 - confirms bidirectional output capability with no internal series resistance. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O with extended common-mode range | Enables direct connection to transducers operating at sub-GND or above-VCC levels - eliminates level-shifting ICs in sensor front-ends. |
| 120ns propagation delay at micropower consumption | Delivers timing-critical response (e.g., motor phase detection) without compromising battery runtime in portable medical devices. |
| Internal ±2.5mV hysteresis | Prevents false triggering on noisy analog signals (e.g., IR receiver outputs) without requiring external feedback resistors. |
| Push-pull output sourcing/sinking 8mA | Drives standard logic families (74LVC, CMOS) and indicator LEDs directly - reduces BOM count by eliminating discrete drivers. |
| No phase reversal with overdriven inputs | Guarantees predictable output polarity even when inputs exceed rails by 0.3V - critical for fault-detection circuits. |

Use Scenario: Precise zero-crossing detection of 50/60Hz mains voltage for energy metering ASIC synchronization. IC Role / Device Role / Timing Role: One comparator channel used with hysteresis to reject noise near 0V crossing; remaining channels monitor auxiliary signals. Use Value: 120ns delay ensures <1.5° phase error at 60Hz; input bias current <1pA prevents loading of high-impedance voltage dividers. | Use Scenario: Translating mixed-voltage logic between 5V microcontrollers, 3.3V FPGAs, and 1.8V ADCs in embedded test equipment. IC Role / Device Role / Timing Role: Three comparators configured as level shifters (e.g., 5V→3.3V, 3.3V→1.8V, 5V→1.8V); fourth monitors power-good status. Use Value: Push-pull outputs eliminate external pull-ups; rail-to-rail swing guarantees valid logic HIGH/LOW across all voltage domains. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Open-collector outputs, 1.3mA supply current per comparator, 300ns delay, no rail-to-rail inputs. | Requires external pull-ups and level-shifting for modern low-voltage systems; unsuitable for battery-powered designs. | Select only if legacy 5V-only systems with high drive strength (>16mA) are required and power is not constrained. |
| TLV3704IPW | Push-pull outputs, 850nA supply current, 3.5μs delay, rail-to-rail inputs, 14-pin TSSOP package. | Ultra-low power but too slow for timing-critical zero-crossing or fast PWM monitoring; better for sleep-mode wake-up triggers. | Choose when nanowatt operation dominates timing requirements - e.g., wireless sensor nodes with multi-day sleep cycles. |
Compared with LM339DR and TLV3704IPW, the MAX995EUD+T uniquely balances speed (120ns), micropower (48μA), rail-to-rail I/O, and push-pull drive - making it optimal for compact, responsive, battery-aware multi-threshold systems where layout space and supply stability are critical.

FAQ
What is the maximum capacitive load the MAX995EUD+T can drive while maintaining 120ns propagation delay?
The MAX995EUD+T maintains ≤120ns propagation delay for input overdrive ≥100mV with capacitive loads up to 50pF at VCC = 5V. At 200pF, delay increases to 40ns (rise/fall), confirming stable operation into typical PCB traces and logic inputs without added buffering. This is verified in the Typical Operating Characteristics figure TOC8.
Does the MAX995EUD+T require external hysteresis for reliable operation with noisy sensor inputs?
No - the MAX995EUD+T includes internal ±2.5mV hysteresis, sufficient to suppress chatter on inputs with slew rates as low as 10mV/ms. External hysteresis is optional and only needed for wider bands (e.g., >20mV); the datasheet provides resistor calculation methods for such cases in Application Information section.
Can the MAX995EUD+T operate from a single 3.3V supply while interfacing with 5V logic?
Yes - the MAX995EUD+T operates from +2.5V to +5.5V, so 3.3V is fully supported. Its push-pull outputs swing rail-to-rail: VOH ≈ 3.15V (at ISOURCE = 3.5mA, TA = +25°C), which exceeds TTL and 3.3V CMOS input HIGH thresholds. For 5V logic interfacing, add a series resistor (e.g., 1kΩ) to limit current if driving 5V-tolerant inputs.
What is the absolute maximum voltage allowed on the IN+ and IN– pins relative to VEE?
The MAX995EUD+T allows input voltages from VEE – 0.3V to VCC + 0.3V per Absolute Maximum Ratings. With VEE = 0V and VCC = 5.5V, inputs may safely range from –0.3V to +5.8V. This 0.3V margin prevents latch-up and enables robust interfacing with signals slightly exceeding supply rails - confirmed in Note 2 of the Electrical Characteristics table.
How does the MAX995EUD+T minimize supply-line disturbances during output transitions?
The MAX995EUD+T employs a patented output stage that limits supply-current surge to <100μA during switching - less than 2× its quiescent current. This virtually eliminates supply glitches, removing the need for large local bypass capacitors. Measured data shows only 100μA increase at 1MHz switching frequency (Figure TOC2), enabling cleaner power domains in mixed-signal systems.
