Product details
Overview
The MAX913EPA+ from Maxim Integrated is a single, ultra-fast, low-power precision TTL comparator with differential inputs and complementary TTL outputs, featuring 10ns typical propagation delay, ±5V or single +5V supply operation, and stable linear-region behavior-ideal for high-speed zero-crossing detection and switching regulator feedback in industrial and embedded power systems.
For engineers reviewing the MAX913EPA+ datasheet, MAX913EPA+ pinout, MAX913EPA+ application, or MAX913EPA+ equivalent, key selection considerations include input common-mode range extending below the negative rail (–0.2V to +3.5V on +5V supply), latch-enable functionality, 0.8mV offset voltage, and 6mA supply current per comparator under +5V operation.
Technical Context
The MAX913EPA+ employs a fully differential bipolar input amplifier with trimmed offset and no built-in hysteresis, enabling high-resolution comparison of slow-moving or low-amplitude signals without oscillation in the linear region. 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 bias, and –0.2V to +3.5V under +5V bias-supporting rail-to-rail input capability below the negative rail.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 10ns typical (ΔVIN = 100mV, VOD = 20mV); enables ≤85MHz signal discrimination with 20mV overdrive. |
| Input Offset Voltage | 0.8mV typical at +25°C; ensures high DC accuracy for precision threshold detection. |
| Supply Current | 6mA per comparator at +5V; supports low-power battery- or energy-constrained designs. |
| Input Common-Mode Range | –0.2V to +3.5V on single +5V supply; allows direct interfacing with ground-referenced sensors or DACs. |
| Output Type | Complementary TTL outputs (Q and Q̅); drives standard logic loads without level-shifting. |
| Latch Enable Function | LE pin controls transparency/latching; eliminates need for external sample-and-hold circuitry. |
| Operating Temperature | –40°C to +85°C; qualified for industrial-grade environmental reliability. |
Pinout & Package
MAX913EPA+ is housed in an 8-pin plastic DIP (dual in-line package) with 0.300-inch body width and through-hole mounting compatibility.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | V+ | Positive supply input (+5V or +4.5V to +5.5V); powers analog and digital sections; requires local 0.1µF ceramic bypass. |
| 2 | IN+ | Noninverting input; accepts signals within full common-mode range including below GND. |
| 3 | IN− | Inverting input; differential pair with IN+; supports rail-to-rail input operation. |
| 4 | V− | Negative supply (–5V) or GND for single-supply mode; powers analog section only. |
| 5 | LE | Latch enable: TTL-high or floating → latches outputs; TTL-low → transparent mode. |
| 6 | GND | Logic ground reference; must be connected to system ground plane. |
| 7 | Q | TTL-compatible active-high output; sinks up to 10mA, sources up to 4mA. |
| 8 | Q̅ | Complementary TTL output; inverted logic state of Q; enables differential signaling or reset logic. |
Key Features
| Feature | Design Value |
|---|---|
| No minimum input slew-rate requirement | Enables reliable comparison of slow triangle or sine waves without added hysteresis or external conditioning. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1016CN8#PBF | Slower (25ns propagation delay), higher supply current (10mA), narrower input common-mode range (–3.5V to +3.5V on ±5V). | Lacks latch-enable function; requires external flip-flop for sampled comparison. | Choose when legacy footprint compatibility is required and speed/power trade-offs are acceptable. |
| LM311N/NOPB | Significantly slower (200ns), open-collector output (requires pull-up), no latch, wider offset (2mV), no linear-region stability guarantee. | Not suitable for zero-crossing or low-slew applications without hysteresis; limited to basic threshold detection. | Choose only for cost-sensitive, non-critical DC comparisons where speed and resolution are secondary. |
Compared with LT1016CN8#PBF and LM311N/NOPB, the MAX913EPA+ delivers superior speed, lower power, guaranteed linear-region stability, and integrated latch functionality-making it the preferred choice for precision high-speed timing, sampling, and industrial feedback loops where signal integrity and deterministic behavior are essential.

FAQ
What supply voltages does the MAX913EPA+ support?
The MAX913EPA+ operates from a single +5V supply (with V− tied to GND) or dual ±5V supplies. Absolute maximum ratings allow +7V on V+ and –7V on V−, but specified performance is guaranteed only from +4.5V to +5.5V (V+) and –5V (V−). Bypass capacitors (0.1µF ceramic + 10µF tantalum) are required at both supply pins for stable high-speed operation.
Does the MAX913EPA+ require hysteresis for stable operation?
No-the MAX913EPA+ is specifically designed to remain stable in its linear region without hysteresis. Unlike many high-speed comparators, it avoids oscillation near zero differential input, enabling accurate resolution of low-slew signals. Adding external hysteresis degrades resolution and is not recommended unless noise immunity outweighs precision requirements in the MAX913EPA+ application.
What is the function of the LE pin on the MAX913EPA+?
The LE (Latch Enable) pin on the MAX913EPA+ controls output transparency versus latching: when LE is TTL-high or floating, Q and Q̅ hold their last valid state; when LE is low, outputs respond immediately to input differential voltage. This eliminates need for external flip-flops in sampled-data systems and enables precise timing control of comparison events in the MAX913EPA+ design.
Can the MAX913EPA+ operate with input signals below ground?
Yes-the MAX913EPA+ supports input common-mode voltages down to –0.2V on single +5V supply and –5.2V on ±5V supply, meaning signals can extend below the negative rail (GND or –5V). This rail-to-rail input capability allows direct interfacing with sensors, DACs, or transducers whose outputs swing negative relative to system ground in the MAX913EPA+ circuit.
How does the MAX913EPA+ differ from the dual MAX912EPE?
The MAX913EPA+ is a single comparator with identical electrical specs (10ns delay, 0.8mV offset, latch function) as one channel of the MAX912EPE-but lacks the second comparator and independent latch control (LEA/LEB). The MAX912EPE offers two matched channels in one package, while the MAX913EPA+ saves board space and cost in single-channel applications requiring the same precision and speed.
