Product details
Overview
MAX9011EUT+T from Maxim Integrated is a single, high-speed, precision TTL comparator operating from a 4.5V to 5.5V single supply. It features 5ns typical propagation delay, 900µA quiescent current, ±7mV input offset voltage, latch enable (LE) input, and stable operation with slow-moving or low-overdrive inputs. It is used in high-speed line receivers and zero-crossing detectors where low-power, fast response, and rail-to-rail input capability are critical.
For engineers reviewing the MAX9011EUT+T datasheet, MAX9011EUT+T pinout, MAX9011EUT+T application, or MAX9011EUT+T equivalent, this page delivers verified electrical parameters, SOT23-6 package details, latch timing behavior, TTL output compatibility, and real-world design context for signal conditioning and timing-critical edge detection.
Technical Context
The MAX9011EUT+T employs a bipolar input stage with fully differential architecture, enabling stable linear-region operation without oscillation-eliminating need for external hysteresis. Its input common-mode range extends to −0.2V (200mV below ground) and up to VCC − 1.9V, supporting true single-supply signal acquisition across full dynamic range.
It integrates a TTL-compatible latch enable (LE) input that places the output in transparent mode when LE = LOW and holds the last valid state when LE = HIGH. Propagation delay remains consistent at 5ns (typ) under 5pF load and 100mV overdrive, with latch setup/hold times of 2ns/0.5ns and latch propagation delay of 5ns-enabling precise synchronous sampling in digital control loops.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 5ns typical at 5pF load and 100mV overdrive - enables sub-10ns decision timing for 100+ MHz edge detection. |
| Supply Voltage Range | 4.5V to 5.5V - compatible with standard 5V logic rails and tolerant of ±5% regulation variation. |
| Quiescent Current | 0.9mA typical - supports battery-powered or thermally constrained designs requiring low static power. |
| Input Offset Voltage | ±7mV max over −40°C to +85°C - ensures <10mV decision threshold uncertainty in precision thresholding applications. |
| Input Common-Mode Range | −0.2V to VCC − 1.9V - allows direct interface to signals referenced below ground (e.g., AC-coupled sensors). |
| Output Type | TTL-compatible push-pull - drives standard 74LS/TTL loads without level-shifting or pull-up resistors. |
| Latch Enable Function | LE pin with VIH = 2V, VIL = 0.8V - enables synchronous capture of comparator state using standard logic-level control signals. |
Pinout & Package
The MAX9011EUT+T is housed in a 6-pin SOT23 package (JEDEC MO-178AA), with 1.27mm pitch, 2.9mm × 1.6mm footprint, and 1.1mm max height - optimized for space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Active-high TTL output; sinks 4mA at VOL ≤ 0.6V, sources 4mA at VOH ≥ 2.4V (VCC = 4.5V). |
| 2 | GND | Analog/digital ground reference; must be connected to low-impedance system ground plane. |
| 3 | IN+ | Noninverting input; accepts signals within −0.2V to VCC − 1.9V common-mode range. |
| 4 | IN− | Inverting input; matched to IN+ for precision differential comparison. |
| 5 | VCC | Positive supply pin; requires local 0.1µF ceramic bypass capacitor placed adjacent to pin. |
| 6 | LE | Latch enable input; TTL-compatible; latches output when HIGH, transparent when LOW. |
Key Features
| Feature | Design Value |
|---|---|
| No minimum input slew-rate requirement | Enables reliable DC–200MHz operation with low-overdrive or slowly varying inputs (e.g., triangle waves, sensor outputs). |
| Stable linear-region behavior | Eliminates need for external hysteresis, preserving resolution and bandwidth in precision threshold detection. |
| Input range extends 200mV below ground | Supports direct interfacing to AC-coupled or bipolar analog sources without level-shifting circuitry. |
| 5ns propagation delay with latch control | Allows synchronized sampling of fast transients while decoupling decision timing from downstream logic clocks. |
| Low 900µA quiescent current | Reduces thermal load and extends battery life in portable instrumentation and always-on monitoring systems. |
Applications
| High-Speed Line Receivers | Zero-Crossing Detectors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9013EUA+ | Complementary TTL outputs (OUT/OUTB), same latch function, 1.3mA ICC, ±5.5mV VOS (tighter than MAX9011EUT+T). | Required where dual-phase logic outputs drive differential receivers or eliminate external inverters. | Select MAX9013EUA+ when complementary outputs reduce component count or improve noise immunity in balanced signaling paths. |
| LMH7220MK/NOPB | 3.5ns propagation delay, 2.5mA ICC, rail-to-rail input (−0.2V to VCC+0.2V), CMOS output - not TTL-compatible. | Suitable for ultra-low-latency sampling but requires level-shifting or gate buffering for TTL logic interfaces. | Choose LMH7220MK/NOPB only if sub-4ns delay is mandatory and system logic accepts CMOS voltage levels or added interface circuitry. |
Compared with MAX9011EUT+T, MAX9013EUA+ offers tighter offset and dual outputs at higher supply current, while LMH7220MK/NOPB delivers faster speed but sacrifices TTL compatibility and increases power-making MAX9011EUT+T optimal for cost-sensitive, space-constrained 5V systems needing latch-synchronized TTL outputs.

FAQ
What is the maximum input overdrive voltage the MAX9011EUT+T can handle without damage?
The MAX9011EUT+T supports analog input voltages from −0.3V to (VCC + 0.3V) - meaning at VCC = 5.5V, inputs may safely reach −0.3V to +5.8V. This exceeds the specified common-mode range (−0.2V to VCC − 1.9V) and protects against transient overvoltage. The device will make correct logic decisions as long as at least one input remains within the common-mode range; both inputs outside that range yield indeterminate output.
Does the MAX9011EUT+T require external hysteresis for stable operation?
No, the MAX9011EUT+T does not require external hysteresis. Its unique bipolar input design prevents oscillation in the linear region, even with slow-moving or low-overdrive inputs. Adding hysteresis degrades resolution and is unnecessary - the MAX9011EUT+T maintains stable output and full bandwidth without it, unlike many competing high-speed comparators.
What is the purpose of the LE (Latch Enable) pin on the MAX9011EUT+T?
The LE pin on the MAX9011EUT+T controls synchronous capture of the comparator output state. When LE is LOW, the output follows the IN+/IN− differential voltage in real time (transparent mode). When LE is driven HIGH, the current output state is latched and held, regardless of subsequent input changes - enabling precise timing-aligned sampling in digital control systems.
Can the MAX9011EUT+T operate from a 3.3V supply?
No, the MAX9011EUT+T is specified only for 4.5V to 5.5V operation. Its TTL-compatible output stage, internal biasing, and propagation delay performance are guaranteed within this range. Operation below 4.5V risks undefined output levels, increased propagation delay, and potential failure to meet datasheet timing or drive specifications - use a 5V regulator or select a 3.3V-compatible comparator instead.
What is the input capacitance of the MAX9011EUT+T, and how does it affect high-frequency performance?
The MAX9011EUT+T has an input capacitance of 1.2pF (per input). This low value minimizes loading on high-impedance or high-frequency sources, preserving signal integrity and reducing propagation delay degradation caused by source-capacitance interaction. At 100MHz, this capacitance contributes <0.2Ω reactance, making it negligible in most PCB trace and filter design contexts when paired with proper layout practices.
