Product details
Overview
The MAX913EUA+T from Maxim Integrated is a single, ultra-fast, low-power precision TTL comparator with differential inputs and complementary TTL outputs, 10ns typical propagation delay, ±5V or +5V single-supply operation, and stable linear-region behavior-ideal for high-speed zero-crossing detection and switching regulator feedback in industrial power systems.
For engineers reviewing the MAX913EUA+T datasheet, MAX913EUA+T pinout, MAX913EUA+T application, or MAX913EUA+T equivalent, this page delivers verified electrical parameters, µMAX package details, latch-enabled comparator functionality, and real-world design context for timing-critical analog-digital interface circuits.
Technical Context
The MAX913EUA+T employs a fully differential bipolar input stage with trimmed offset voltage (0.8mV typ) and extends common-mode input range to −0.2V on single +5V supply or −5.2V on ±5V supply. Its latch-enable architecture allows transparent or latched output control without external logic.
Unlike conventional high-speed comparators, it eliminates oscillation in the linear region-enabling accurate resolution of slow-moving or low-overdrive signals without added hysteresis. This stability is achieved via internal biasing and gain-stage design, not external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 10ns typical at 100mV overdrive - enables >70MHz signal edge detection in timing-critical sampling circuits. |
| Supply Voltage Range | +4.5V to +5.5V (single) or ±5V (dual) - supports legacy 5V logic rails and isolated ±5V analog domains. |
| Input Offset Voltage | 0.8mV typical at +25°C - ensures sub-millivolt threshold accuracy in precision level-shift and V/F converter applications. |
| Supply Current | 6mA per comparator at +5V - reduces thermal load and enables battery-backed or low-quiescent designs. |
| Common-Mode Input Range | −0.2V to +3.5V (single +5V) - allows direct interfacing with ground-referenced sensors and rail-to-rail input signals. |
| Output Type | Complementary TTL - drives standard 74LS/74F logic directly without level-shifting or pull-ups. |
| Latch Enable Function | LE pin controls transparency/latching - synchronizes comparator decision to system clock, eliminating metastability in sampled-data systems. |
Pinout & Package
MAX913EUA+T is housed in an 8-pin µMAX (uMAX) package - 3.05mm × 3.05mm × 0.8mm body, 0.5mm pitch, exposed pad for thermal enhancement, RoHS-compliant and halogen-free.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | V+ | Positive supply input - powers both analog input stage and TTL output drivers; requires local 0.1µF ceramic bypass to GND. |
| 2 | IN+ | Noninverting input - accepts differential signals up to 3.5V above GND or −5.2V below V− in dual-supply mode. |
| 3 | IN− | Inverting input - matched to IN+ for <2mV offset; no minimum slew-rate requirement enables use with slow triangle waves. |
| 4 | V− | Negative supply or GND - defines lower rail of input common-mode range; bypassed separately for noise immunity. |
| 5 | LE | Latch enable - TTL-high or floating = latched output; TTL-low = transparent mode; critical for synchronous sampling. |
| 6 | GND | Logic ground reference - must be connected to system ground plane; shared return for supply bypass and output loads. |
| 7 | Q | TTL output - active-high logic-level output (VOH ≥ 2.4V @ 10mA sink); drives 74LS fanout directly. |
| 8 | Q̅ | Complementary TTL output - inverted copy of Q; enables differential signaling or reset/set logic without external inverters. |
Key Features
| Feature | Design Value |
|---|---|
| Stable linear-region operation | Eliminates need for external hysteresis - preserves full input resolution down to DC, unlike oscillating comparators. |
| No input slew-rate requirement | Valid output guaranteed even with µV/s input ramps - essential for V/F converters and precision zero-crossing detectors. |
| Wide input common-mode range | Extends 200mV below negative rail - supports ground-referenced inputs on ±5V supplies and rail-to-rail sensing. |
| Low power consumption | 6mA total supply current at +5V - enables integration into thermally constrained or portable power-monitoring modules. |
| Complementary TTL outputs | Q and Q̅ drive standard logic families directly - reduces BOM count and PCB area vs. discrete inverter solutions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1016CS8#PBF | 11ns propagation delay; higher 8mA supply current; narrower −2.5V to +3.5V input range on ±5V supply. | Lacks linear-region stability - requires hysteresis for reliable slow-signal operation, reducing resolution. | Choose only if legacy LT1016 footprint compatibility is mandatory; MAX913EUA+T offers superior DC accuracy and noise immunity. |
| ADCMP572BCPZ-R7 | 4.5ns propagation delay; ECL/PECL outputs; requires −5.2V supply; no latch function; 15mA supply current. | Designed for RF/IF sampling, not general-purpose analog-digital interfacing; incompatible TTL logic levels. | Select only for ultra-high-speed (>1GSPS) sampling systems; MAX913EUA+T better suits industrial control with TTL interoperability. |
Compared with LT1016CS8#PBF and ADCMP572BCPZ-R7, the MAX913EUA+T uniquely balances nanosecond speed, TTL compatibility, latch control, and linear-region stability-making it optimal for cost-sensitive, precision timing applications where resolution and supply simplicity matter.

FAQ
What is the operating temperature range for the MAX913EUA+T?
The MAX913EUA+T is rated for −40°C to +85°C operation, validated across the full range for key parameters including propagation delay, input offset voltage, and supply current. This makes the MAX913EUA+T suitable for industrial environments such as motor drives, power supplies, and outdoor instrumentation where ambient temperatures fluctuate widely.
Does the MAX913EUA+T require external hysteresis for stable operation?
No-the MAX913EUA+T is specifically designed to remain stable in its linear region without external hysteresis. Its internal architecture prevents oscillation during slow input transitions, preserving resolution for low-frequency signals like triangle waves or V/F converter outputs. Adding hysteresis to the MAX913EUA+T degrades accuracy and is unnecessary.
Can the MAX913EUA+T operate from a single +5V supply?
Yes-the MAX913EUA+T supports single +5V operation with V− tied to GND. In this configuration, its input common-mode range is −0.2V to +3.5V, allowing direct connection to ground-referenced sources. The MAX913EUA+T maintains 10ns typical propagation delay and 6mA supply current under single-supply conditions.
What is the function of the LE (latch enable) pin on the MAX913EUA+T?
The LE pin on the MAX913EUA+T controls output latching: when LE is high or floating, the Q and Q̅ outputs hold their last valid state; when LE is low, the outputs respond transparently to input differential voltage. This feature enables synchronous sampling in digital control loops and eliminates metastability in clocked systems using the MAX913EUA+T.
Is the MAX913EUA+T pin-compatible with other packages in the MAX913 family?
No-the MAX913EUA+T uses the 8-pin µMAX package, while MAX913CPA (DIP) and MAX913CSA (SO) use different footprints and pinouts. Although all share identical electrical functionality and pin naming, mechanical compatibility requires matching the µMAX land pattern. The MAX913EUA+T is not a drop-in replacement for SO or DIP variants without PCB redesign.
