Product details
Overview
MAX9013EUA-T from Maxim Integrated is a single high-speed precision comparator with complementary TTL outputs and latch enable, operating from 4.5V to 5.5V. It delivers 5ns typical propagation delay, ±5.5mV max input offset voltage over -40°C to +85°C, and stable operation with slow-moving or low-overdrive inputs - ideal for zero-crossing detection and high-speed sampling circuits.
For engineers reviewing the MAX9013EUA-T datasheet, MAX9013EUA-T pinout, MAX9013EUA-T application, or MAX9013EUA-T equivalent, this device is selected for low-power, single-supply timing-critical systems requiring latch functionality, rail-to-rail input capability down to -0.2V, and deterministic output behavior without hysteresis or minimum slew-rate constraints.
Technical Context
The MAX9013EUA-T uses a fully differential bipolar input stage with no built-in hysteresis, enabling high-resolution comparison in the linear region without oscillation. Its latch enable (LE) input provides synchronous output hold functionality, with 2ns setup and 0.5ns hold time relative to LE assertion.
It features complementary outputs (OUT/OUTB), allowing direct interface to differential logic or noise-immune signal routing. The input common-mode range extends from -0.2V to (VCC – 1.9V), supporting ground-referenced signals and enabling use in single-supply systems without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 5ns typical at 5pF load and 100mV overdrive - enables sub-200MHz signal edge detection. |
| Input Offset Voltage | ±5.5mV max over full temperature range - ensures ≤10mV decision error in precision threshold applications. |
| Supply Current | 1.3mA typical at +25°C - supports battery-sensitive or thermally constrained designs. |
| Common-Mode Range | -0.2V to (VCC – 1.9V) - allows direct sensing of signals referenced to ground on 5V supply. |
| Output Type | TTL-compatible complementary outputs - eliminates need for external inverters in differential logic paths. |
| Latch Enable | Active-high TTL-compatible LE input - enables synchronized capture of transient events in digital control loops. |
| Operating Temp | -40°C to +85°C - qualified for industrial and automotive under-hood environments. |
Pinout & Package
MAX9013EUA-T is housed in an 8-pin µMAX package (3mm × 3mm, 0.8mm height), pin-compatible with industry-standard SO-8 but with significantly reduced footprint and thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | True TTL output - drives high when IN+ > IN−; sinks 4mA at 0.6V max. |
| 2 | GND | Analog/digital ground reference - must be connected to low-impedance system ground plane. |
| 3 | IN+ | Noninverting input - accepts signals down to -0.2V; differential pair bias current ±0.5µA max. |
| 4 | IN− | Inverting input - matched to IN+ for <2ns channel-to-channel skew in dual variants. |
| 5 | VCC | Positive supply - requires local 0.1µF ceramic bypass to GND for stable high-speed operation. |
| 6 | LE | Latch enable - TTL-high (≥2V) freezes output state; low enables transparent comparison mode. |
| 7 | OUTB | Complementary TTL output - low when IN+ > IN−; matches OUT timing within 3ns differential delay. |
| 8 | N.C. | No connection - internal die pad not bonded; recommended to tie to GND for thermal and EMI performance. |
Key Features
| Feature | Design Value |
|---|---|
| Stable linear-region operation | Eliminates need for external hysteresis, preserving resolution for signals near threshold crossing. |
| No minimum input slew rate | Supports DC–200MHz input signals including triangle waves and low-overdrive sine edges. |
| Ground-sensing input range | Accepts inputs 200mV below GND without phase reversal - enables true bipolar signal conditioning on single 5V rail. |
| Complementary TTL outputs | Reduces board space and component count vs. discrete inverter solutions in differential clock/data paths. |
| Latch function with tight timing | 2ns setup / 0.5ns hold enables reliable capture of nanosecond-scale events in FPGA or microcontroller interfaces. |
Applications

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 10ns propagation delay; higher 2.5mA supply current; no latch or complementary outputs. | Suitable for general-purpose comparators where latch synchronization is unnecessary and speed margin >5ns is acceptable. | Select LT1016CS8#PBF only if legacy design reuse or cost sensitivity outweighs need for latch function and 5ns timing. |
| MAX9011EUT-T | Same family, same 5ns delay and latch, but single-ended output only; offered in SOT23-6 (smaller footprint). | Preferred for space-constrained designs where complementary outputs are not required and µMAX pinout compatibility is not needed. | Choose MAX9011EUT-T when board area is critical and differential signaling is not used in the target signal path. |
Compared with LT1016CS8#PBF and MAX9011EUT-T, the MAX9013EUA-T uniquely combines latch enable, complementary outputs, and 5ns speed in an 8-pin µMAX package - making it the only option among the three for synchronous, noise-resilient, high-speed threshold detection with minimal external components.

FAQ
What is the maximum input overdrive voltage supported by the MAX9013EUA-T without damage?
The MAX9013EUA-T supports analog input voltages from -0.3V to (VCC + 0.3V) - meaning up to +5.8V on a 5.5V supply. This absolute rating applies per input pin (IN+, IN−), and damage is avoided as long as both pins remain within these limits. The functional common-mode range remains -0.2V to (VCC – 1.9V), but correct logic decisions occur if at least one input stays within that window.
Does the MAX9013EUA-T require external hysteresis for stable operation?
No - the MAX9013EUA-T is explicitly designed to operate stably in its linear region without external hysteresis. Its architecture prevents oscillation during slow input transitions or low-overdrive conditions, preserving resolution around the threshold. Adding hysteresis degrades accuracy and is unnecessary unless intentional noise immunity is required at the cost of decision window widening.
How does the latch enable (LE) pin affect output behavior in the MAX9013EUA-T?
When LE is low (≤0.8V), the MAX9013EUA-T operates transparently: OUT and OUTB respond immediately to input differential voltage. When LE is high (≥2V), the current output state is latched and held regardless of subsequent input changes. The latch timing parameters - 2ns setup and 0.5ns hold - ensure reliable capture of nanosecond-scale events in synchronous digital systems.
Can the MAX9013EUA-T operate from a 3.3V supply?
No - the MAX9013EUA-T is specified only for 4.5V to 5.5V operation. Its TTL-compatible outputs, internal biasing, and propagation delay performance are guaranteed only within this range. Attempting 3.3V operation results in undefined output levels, increased propagation delay (>10ns), and potential failure to meet input threshold specifications. For 3.3V systems, consider the MAX9021 or MAX961 series instead.
What is the purpose of Pin 8 (N.C.) on the MAX9013EUA-T µMAX package?
Pin 8 is a no-connect terminal - not internally bonded - but serves as a thermal and EMI shield pad. Maxim recommends connecting Pin 8 to GND via a low-inductance path to improve thermal dissipation and reduce high-frequency noise coupling. Leaving it floating may degrade stability in high-speed layouts or increase susceptibility to radiated interference near the die.
