Product details
Overview
The MAX913ESA from Maxim Integrated is a single, ultra-fast, low-power precision TTL comparator with differential inputs and complementary TTL outputs. It delivers 10ns typical propagation delay, ±5V or +5V single-supply operation, input voltage range extending below the negative rail (–0.2V to +3.5V on +5V supply), 0.8mV max input offset voltage, and stable linear-region operation-enabling reliable zero-crossing detection in switching regulator feedback loops.
For engineers reviewing the MAX913ESA datasheet, MAX913ESA pinout, MAX913ESA application, or MAX913ESA equivalent, this device is selected for high-speed analog-to-digital interface circuits where low power, wide common-mode range, latch-enabled output hold, and oscillation-free linear-region behavior are critical design requirements.
Technical Context
The MAX913ESA implements a fully differential bipolar input stage with laser-trimmed offset and no built-in hysteresis, enabling true high-resolution comparison of slow-moving or low-amplitude signals without output instability. Its latch-enable (LE) pin provides transparent or latched output control independent of input slew rate.
It operates from either single +5V (V− = GND) or dual ±5V supplies, with V+ powering both analog and digital sections while V− powers only the analog stage. Input common-mode range spans –5.2V to +3.5V under ±5V operation, and –0.2V to +3.5V under +5V operation-supporting ground-referenced or negative-rail–referenced signal conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 10ns typical at 100mV overdrive - enables >70MHz signal discrimination in timing-critical sampling circuits. |
| Supply Voltage Range | +4.5V to +5.5V (single) or ±4.5V to ±5.5V (dual) - supports robust operation across industrial supply tolerances. |
| Input Offset Voltage | 0.8mV maximum (–40°C to +85°C) - ensures sub-millivolt resolution in precision threshold detection. |
| Supply Current per Comparator | 6mA typical at +5V - enables battery-sensitive or thermally constrained designs with minimal quiescent load. |
| Input Common-Mode Range | –0.2V to +3.5V on +5V supply - allows direct interfacing with ground-referenced sensors or DACs without level-shifting. |
| Output Type | Complementary TTL - drives standard logic loads directly without external pull-ups or level translators. |
| Latch Enable Function | LE high/floating = latched; LE low = transparent - provides synchronous capture of comparator state for gated measurement systems. |
Pinout & Package
MAX913ESA is housed in an 8-pin SO (Small Outline) package, 150-mil body width, with gull-wing leads and JEDEC MS-012AC outline. Pin 1 is V+, pin 6 is GND, and all pins are electrically defined per the official Maxim pin description.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | V+ | Positive supply input; powers analog input stage and TTL output drivers; requires local 0.1µF ceramic bypass to GND. |
| 2 | IN+ | Noninverting input; accepts signals up to +3.5V on +5V supply or +3.5V relative to V− on ±5V supply. |
| 3 | IN− | Inverting input; supports common-mode voltages down to –0.2V (on +5V) or –5.2V (on ±5V), enabling rail-to-rail sensing. |
| 4 | V− | Negative supply input; tied to GND for single +5V operation; powers analog section only. |
| 5 | LE | Latch enable; TTL-compatible control pin that freezes Q/Q outputs when high or floating; transparent when low. |
| 6 | GND | Logic ground reference; must be connected to system ground plane with low-inductance path. |
| 7 | Q | TTL output; active-high logic level (≥2.4V @ 10mA sink) synchronized to input differential polarity when LE is low. |
| 8 | Q̅ | Complementary TTL output; active-low logic level (≤0.4V @ 10mA sink); provides differential signaling capability. |
Key Features
| Feature | Design Value |
|---|---|
| Stable linear-region operation | Eliminates need for external hysteresis, preserving full input resolution around 0V differential - critical for low-frequency waveform analysis. |
| No minimum input slew-rate requirement | Valid output guaranteed regardless of input edge speed, simplifying interface with slow sensors or filtered signals. |
| Wide input common-mode range | Extends 200mV below V− rail - enables direct connection to current-sense resistors or op-amp outputs referenced to negative supplies. |
| Low power consumption | 6mA per comparator at +5V - reduces thermal load in dense PCB layouts and extends battery life in portable instrumentation. |
| TTL-compatible latch function | Hardware-gated output hold via LE pin - supports synchronous sampling in data acquisition and pulse-width measurement systems. |

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 | Slower propagation delay (15ns typ), higher supply current (7mA), narrower input common-mode range (–3.5V to +3.5V on ±5V) | Lacks latch function; requires external hysteresis for stable linear-region operation | Preferred where legacy compatibility or lower cost outweighs speed and latch needs |
| LM360M/NOPB | Higher offset voltage (2mV max), no latch pin, 25ns propagation delay, TTL output compatible but no complementary output | Not suitable for synchronous sampling or differential output drive; limited resolution in low-overdrive conditions | Selected for basic threshold detection where latch and complementary outputs are unnecessary |
Compared with LT1016CS8#PBF and LM360M/NOPB, the MAX913ESA offers superior timing precision, integrated latch control, and guaranteed stability without hysteresis-making it optimal for next-generation power management and precision measurement systems requiring deterministic response at temperature extremes.

FAQ
What is the operating temperature range for the MAX913ESA?
The MAX913ESA is rated for operation from –40°C to +85°C. This extended industrial temperature range is confirmed in the Ordering Information table and validated across all key specifications-including propagation delay, input offset voltage, and supply current-in the Electrical Characteristics section of the datasheet. The "ESA" suffix explicitly denotes the –40°C to +85°C grade.
Does the MAX913ESA require external hysteresis for stable operation?
No, the MAX913ESA does not require external hysteresis. Its unique internal architecture ensures stable output behavior even when the input differential voltage resides in the linear region-unlike many high-speed comparators that oscillate near zero crossing. This feature is explicitly documented in the General Description and Detailed Description sections, and eliminates resolution loss associated with hysteresis bands.
Can the MAX913ESA operate from a single +5V supply?
Yes, the MAX913ESA supports single +5V supply operation. In this configuration, V− is connected to GND, and the input common-mode range becomes –0.2V to +3.5V. The device draws 6mA typical supply current per comparator under these conditions, and all timing and DC specifications remain valid across the full –40°C to +85°C range.
What is the function of the LE pin on the MAX913ESA?
The LE (Latch Enable) pin on the MAX913ESA controls output transparency versus latching. When LE is high or floating, the Q and Q̅ outputs retain their last valid state; when LE is low, the outputs respond dynamically to the IN+/IN− differential voltage. This hardware latch enables synchronous sampling and eliminates metastability in digital capture systems interfacing with the MAX913ESA.
What package type is used for the MAX913ESA?
The MAX913ESA uses an 8-pin SO (Small Outline) package with 150-mil body width and JEDEC MS-012AC footprint. This surface-mount package measures 4.90mm × 3.90mm × 1.75mm and features gull-wing leads compatible with standard reflow soldering processes. The "ESA" suffix corresponds exclusively to this SO package variant per the Ordering Information table.
