Product details
Overview
MAX907EPA from Maxim Integrated is a dual high-speed, ultra-low-power single-supply TTL comparator in 8-pin PDIP package, featuring 40ns propagation delay (5mV overdrive), 700µA supply current per comparator, and input common-mode range from –0.2V to V+ – 1.5V. It operates from a single +4.5V to +5.5V supply and delivers clean switching via built-in hysteresis - ideal for battery-powered threshold detection and high-speed sampling circuits.
For engineers reviewing the MAX907EPA datasheet, MAX907EPA pinout, MAX907EPA application, or MAX907EPA equivalent, key selection criteria include propagation delay consistency across channels, TTL-compatible output drive without pull-ups, input short-circuit robustness, and compatibility with 0°C to +70°C industrial temperature requirements.
Technical Context
The MAX907EPA implements two independent comparators with internal hysteresis (typical VHYST = 4mV), eliminating external feedback resistors. Its bipolar process enables fast 40ns propagation delay while maintaining low 3.5mW power per comparator at V+ = 5V.
All inputs and outputs tolerate continuous shorting to either supply rail. Input voltage range extends 200mV below ground and up to 1.5V below V+, supporting reliable operation near rail boundaries in single-supply systems.
Key Specifications

|---|---|
| Propagation Delay | 40ns typical (5mV input overdrive) - enables timing-critical sampling at >10MHz rates |
| Supply Current per Comparator | 700µA at V+ = 5V - supports multi-comparator designs in sub-2mA total system budget |
| Input Common-Mode Range | –0.2V to V+ – 1.5V - accepts signals down to 200mV below ground without level-shifting |
| Output Type | TTL-compatible push-pull - drives standard logic loads directly, no external pull-up required |
| Input Offset Voltage | 1mV typical - ensures accurate trip-point stability for precision threshold detection |
| Hysteresis Width | 4mV typical (VTRIP+ – VTRIP–) - suppresses noise-induced oscillation on slow-moving inputs |
| Operating Temperature | 0°C to +70°C - qualified for commercial-grade embedded control and instrumentation |
Pinout & Package
MAX907EPA is housed in an 8-pin plastic DIP (dual in-line package) with 0.3-inch body width and through-hole mounting. Pin spacing is 0.1 inch, compatible with standard PCB layouts and socket footprints.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | V+ | Positive supply input (4.5V to 5.5V); decoupling capacitor must be placed adjacent to this pin |
| 2 | INA+ | Noninverting input of comparator A; referenced to GND or negative rail |
| 3 | INA– | Inverting input of comparator A; differential pair node with matched layout sensitivity |
| 4 | GND | Circuit ground reference; connects to low-inductance ground plane for noise immunity |
| 5 | INB+ | Noninverting input of comparator B; electrically isolated from INA+ but shares same bias network |
| 6 | INB– | Inverting input of comparator B; matched to INA– for inter-channel tracking |
| 7 | OUTB | Active-high TTL output of comparator B; sinks ≥3.2mA at VOL ≤ 0.525V (TMIN) |
| 8 | OUTA | Active-high TTL output of comparator A; sources ≥100µA at VOH ≥ 2.8V |
Key Features
| Feature | Design Value |
|---|---|
| Internal hysteresis | Fixed 4mV input-referred hysteresis eliminates need for external resistor networks and design iteration |
| Rail-to-rail input capability | Operates with inputs as low as –0.2V (below GND) and up to V+ – 1.5V - avoids signal attenuation or clamping diodes |
| TTL-compatible outputs | Push-pull outputs meet standard TTL VOH/VOL specs - interface directly with 74LS/74HC logic without level translation |
| Short-circuit protected I/O | Inputs and outputs withstand indefinite shorting to V+ or GND - simplifies ESD-safe board handling and test fixture design |
| Low propagation delay skew | ≤2ns max skew between channels - preserves timing integrity in dual-threshold or window-detect applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Slower 1.3µs propagation delay; no internal hysteresis; open-collector outputs require pull-up resistors | Suitable only for low-speed, cost-sensitive applications where timing margin exceeds 1µs | Select only if power >10× higher and hysteresis can be added externally |
| TLV3501CDR | Faster 4.5ns delay; rail-to-rail input; CMOS output; 2.7–5.5V supply; higher 1.3mA supply current | Preferred for ultra-high-speed sampling but incompatible with TTL logic families without level shifters | Choose when speed >5× critical and system uses 3.3V logic; avoid if TTL interfacing or sub-1mA budget required |
Compared with LM393DR and TLV3501CDR, the MAX907EPA uniquely balances TTL compatibility, ultra-low power (700µA), and 40ns speed in a single-supply configuration - making it optimal for legacy-compatible, battery-conscious, medium-speed industrial sensing.

FAQ
What is the operating temperature range for MAX907EPA?
The MAX907EPA is rated for 0°C to +70°C ambient operation. This commercial-grade temperature specification aligns with its "CPA" suffix designation in Maxim's ordering nomenclature. The device maintains full electrical performance across this range, including propagation delay variation ≤25ns and input offset drift ≤0.5µV/°C. For extended temperature applications, consider the MAX907EPA's sibling MAX907EPA (–40°C to +85°C) or MAX907MSA/PR (–55°C to +125°C).
Does MAX907EPA support dual ±5V supplies?
No, the MAX907EPA does not support dual ±5V supplies. Only the MAX909 variant in the same family includes a dedicated V– pin and full ±5V operation. The MAX907EPA is strictly a single-supply device, requiring V+ between +4.5V and +5.5V referenced to GND. Attempting to apply negative voltage to any pin beyond the absolute maximum rating of –0.3V will risk permanent damage.
Can MAX907EPA outputs drive standard TTL logic directly?
Yes, MAX907EPA outputs are fully TTL-compatible: VOH ≥ 2.8V (at ISOURCE = 100µA) and VOL ≤ 0.525V (at ISINK = 3.2mA) across temperature. No external pull-up resistors are needed. Each output can sink ≥3.2mA or source ≥100µA while maintaining valid TTL logic levels - enabling direct connection to 74LS, 74F, or microcontroller GPIO pins without interface circuitry.
Is internal hysteresis present in MAX907EPA, and what is its value?
Yes, MAX907EPA incorporates fixed internal hysteresis of approximately 4mV (VTRIP+ – VTRIP–). This hysteresis is implemented on-chip and requires no external components. It ensures clean, chatter-free output transitions even with slowly varying or noisy input signals - critical for reliable threshold detection in real-world environments. The hysteresis center (input offset voltage) is typically 1mV.
What package type is used for MAX907EPA?
The MAX907EPA uses an 8-pin plastic DIP (dual in-line package) with 0.3-inch body width and through-hole leads. This package is designated "PDIP" in industry standards and matches JEDEC MS-001. It is pin-compatible with SO-8 variants (e.g., MAX907CSA) but requires different PCB footprint and assembly processes. Thermal resistance is 9.09mW/°C above +70°C, with 727mW max continuous dissipation at TA = +70°C.
