Product details
Overview
MAX9013EUA+ from Maxim Integrated is a single, high-speed, precision TTL comparator with complementary outputs and latch enable functionality, operating from a 4.5V to 5.5V single supply. It delivers 5ns typical propagation delay, ±5.5mV max input offset voltage over temperature, and stable operation with slow-moving or low-overdrive inputs - ideal for zero-crossing detection and high-speed sampling circuits in industrial and test equipment.
For engineers reviewing the MAX9013EUA+ datasheet, MAX9013EUA+ pinout, MAX9013EUA+ application, or MAX9013EUA+ equivalent, this page provides verified technical context, real-world design meaning for key specs, validated µMAX package details, confirmed latch timing behavior, and two field-validated alternative comparators with documented functional trade-offs.
Technical Context
The MAX9013EUA+ uses a bipolar process with fully differential input amplifiers and no built-in hysteresis, enabling stable linear-region operation without oscillation - eliminating need for external hysteresis and preserving resolution. Its input common-mode range extends from –0.2V to (VCC – 1.9V), supporting ground-referenced signals and negative-going transients.
It integrates a TTL-compatible latch enable (LE) input that freezes output state when asserted high, with guaranteed 2ns setup and 0.5ns hold time. Complementary outputs (OUT/OUTB) provide simultaneous active-high and active-low logic levels, simplifying interface to dual-input logic or differential receivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 5ns typical at 5pF load and 100mV overdrive - enables reliable 200MHz signal edge detection without timing uncertainty. |
| Input Offset Voltage | ±5.5mV max over –40°C to +85°C - ensures sub-10mV threshold accuracy across industrial temperature range. |
| Supply Current | 1.3mA typical at +25°C - supports low-power portable and battery-backed systems without sacrificing speed. |
| Input Common-Mode Range | –0.2V to (VCC – 1.9V) - allows direct interfacing to ground-referenced sensors and rail-to-rail analog sources. |
| Output Type | TTL-compatible complementary outputs - eliminates need for external inverters in dual-level logic interfaces. |
| Latch Enable Function | LE pin with 2V VIH / 0.8V VIL thresholds - enables synchronous capture of comparator decisions using standard digital control signals. |
| Operating Temperature | –40°C to +85°C - qualified for industrial automation, instrumentation, and embedded control environments. |
Pinout & Package
The MAX9013EUA+ is housed in an 8-pin µMAX package (3mm × 3mm, 0.8mm height), thermally enhanced for high-density PCB layouts and compatible with standard SO-8 reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Active-high TTL output; sinks 4mA at 0.6V max - directly drives 74LS/74F logic or microcontroller GPIOs. |
| 2 | GND | Analog/digital ground reference - must be connected to low-impedance system ground plane for noise immunity. |
| 3 | IN+ | Noninverting input; accepts signals down to –0.2V - enables true zero-crossing detection without level-shifting. |
| 4 | IN– | Inverting input; matched to IN+ for <2ns channel-to-channel skew - critical for precise differential thresholding. |
| 5 | VCC | Positive supply (4.5V–5.5V); requires local 0.1µF ceramic bypass - minimizes supply-induced jitter on fast edges. |
| 6 | LE | Latch enable input; TTL-compatible; latches output when high - synchronizes decision capture with system clock or trigger. |
| 7 | OUTB | Complementary (active-low) TTL output; sourced/sunk symmetrically with OUT - supports RS-422-like signaling or OR/NOR logic. |
| 8 | N.C. | No internal connection; recommended tied to GND to reduce parasitic coupling and improve EMI performance. |
Key Features
| Feature | Design Value |
|---|---|
| Stable linear-region operation | Eliminates need for external hysteresis, preserving <10mV resolution and enabling accurate DC-coupled threshold detection. |
| No minimum input slew-rate requirement | Supports reliable comparison of slow triangle waves, low-overdrive sine waves, and low-frequency sensor outputs without false triggering. |
| Complementary TTL outputs | Reduces BOM count by removing need for discrete inverters in dual-signal paths such as set/reset latches or differential receivers. |
| Latch enable with guaranteed timing | Enables deterministic sampling of transient events (e.g., pulse-width measurement) with ≤2ns setup window relative to LE assertion. |
| Ground-extending input range | Accepts inputs 200mV below GND without phase reversal - simplifies interfacing to op-amp stages or AC-coupled sources. |
Applications
| Zero-Crossing Detection | High-Speed Sampling Circuits |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, single-supply comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX913ESA+ | Same pinout, but no latch or complementary outputs; 8ns propagation delay; higher 2.5mA supply current. | Lacks synchronous capture capability and dual-output flexibility - suitable only for basic threshold detection. | Select MAX913ESA+ only if latch and complementarity are unnecessary and board layout reuse is critical. |
| LT1016CS8#PBF | Higher 10ns propagation delay; ±1.5mV offset at 25°C but wider ±7mV over temperature; no latch; SO-8 package. | Superior DC precision at room temperature but less consistent over temperature; no LE or OUTB pins. | Choose LT1016CS8#PBF when ultra-low offset at 25°C outweighs speed and feature requirements. |
Compared with MAX9013EUA+, MAX913ESA+ offers identical footprint but sacrifices latch control and speed, while LT1016CS8#PBF trades 5ns latency for better room-temperature offset - making MAX9013EUA+ optimal for time-critical, feature-rich industrial sensing where both speed and synchronous capture matter.

FAQ
What is the maximum input overdrive voltage the MAX9013EUA+ can handle without damage?
The MAX9013EUA+ supports analog input voltages from –0.3V to (VCC + 0.3V) without permanent damage. This means at VCC = 5.5V, inputs may safely reach up to +5.8V or as low as –0.3V. However, correct logic decisions require at least one input within the specified common-mode range of –0.2V to (VCC – 1.9V). The MAX9013EUA+ maintains stable output behavior even with overdriven inputs - no phase reversal occurs.
Does the MAX9013EUA+ require external hysteresis for stable operation?
No, the MAX9013EUA+ does not require external hysteresis. Its unique bipolar architecture prevents oscillation in the linear region, enabling stable output even with slow-moving or low-overdrive inputs. Adding hysteresis would degrade resolution - the MAX9013EUA+ achieves <10mV effective threshold resolution without it, as confirmed by its ±5.5mV max input offset voltage and absence of instability in typical operating characteristics.
Can the MAX9013EUA+ operate from a 3.3V supply?
No, the MAX9013EUA+ is specified only for 4.5V to 5.5V single-supply operation. Electrical characteristics including propagation delay, output drive strength, and input common-mode range are guaranteed only within this range. Attempting 3.3V operation risks failure to meet timing specs, reduced noise margin, or undefined output states - use MAX9060 or MAX9021 for 3.3V-compatible high-speed comparators.
What is the purpose of the N.C. pin (Pin 8) on the MAX9013EUA+?
Pin 8 of the MAX9013EUA+ is a no-connect terminal with no internal connection. Maxim recommends tying it to ground to minimize parasitic coupling, reduce EMI susceptibility, and improve high-frequency stability - especially important in dense layouts near RF or switching nodes. Leaving Pin 8 floating may increase noise pickup and degrade propagation delay consistency in sensitive applications.
How does the latch enable (LE) function behave during power-up of the MAX9013EUA+?
During power-up, the MAX9013EUA+ output remains in a high-impedance or indeterminate state until VCC stabilizes above ~4.0V and internal biasing settles (~1µs power-up time). The LE pin has no defined behavior until VCC reaches specification; therefore, LE must be held low (transparent mode) or controlled by a sequenced logic signal after power stabilization. Driving LE high before full power-up may result in metastability - best practice is to assert LE only after VCC and system clocks are stable.
