Product details
Overview
The MAX9107ESA-T from Maxim Integrated is a dual high-speed, low-power voltage comparator operating from a single +5V supply, featuring 25ns propagation delay (10mV overdrive), 350µA per comparator supply current, and TTL-compatible outputs with internal 2mV hysteresis-used in A/D converter front-ends and threshold detection circuits.
For engineers reviewing the MAX9107ESA-T datasheet, MAX9107ESA-T pinout, MAX9107ESA-T application, or MAX9107ESA-T equivalent, key selection criteria include propagation delay vs. power trade-off, input common-mode range down to 200mV below ground, latch absence (vs. MAX9109), and SO-8 package compatibility for space-constrained industrial sensing designs.
Technical Context
The MAX9107ESA-T implements a bipolar process-based comparator core with rail-to-rail input capability (–0.2V to VCC–1.5V), enabling direct ground-referenced signal comparison without level-shifting. Its internal hysteresis eliminates external feedback components while ensuring clean switching on slow-moving inputs.
Each comparator channel features independent IN+ and IN– inputs, open-collector–compatible TTL outputs (VOH = 3.0V min at 100µA, VOL = 0.6V max at 3.2mA), and operates across –40°C to +85°C with guaranteed 4.5V–5.5V supply tolerance and 500µV typical offset voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 25ns at 10mV input overdrive - enables sampling of >10MHz analog events in real-time discriminators. |
| Supply Current per Comparator | 350µA (1.75mW) at VCC = 5.5V - supports battery-powered systems with multi-comparator configurations. |
| Input Common-Mode Range | –0.2V to VCC–1.5V - accepts signals referenced to ground or negative offsets without clamping diodes. |
| Input Offset Voltage | 0.5–4.0mV (max) - ensures accurate threshold detection in precision zero-crossing and line receiver applications. |
| Hysteresis Width | 2mV - suppresses noise-induced oscillation during slow-slew input transitions without external components. |
| Output Compatibility | TTL logic levels (VOH ≥ 3.0V, VOL ≤ 0.6V) - interfaces directly with 74LS/74F logic without pull-up resistors. |
| Operating Temperature | –40°C to +85°C - qualified for industrial control and automotive under-hood sensor conditioning. |
Pinout & Package
MAX9107ESA-T is housed in an 8-pin SO (Small Outline) package (package code S8-2), with exposed pad not present and RoHS-compliant lead finish.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | N.C. | No internal connection - must be left unconnected or tied to GND for mechanical stability. |
| 2 | OUTA | Channel A TTL-compatible output - sinks up to 8mA or sources 100µA; drives logic inputs directly. |
| 3 | GND | Analog/digital ground reference - requires low-inductance plane connection to minimize switching noise coupling. |
| 4 | LE | Latch Enable - not used in MAX9107; must be tied to GND or VCC (not floating) per datasheet guidance. |
| 5 | VCC | Positive supply (4.5V–5.5V) - requires 0.1µF ceramic decoupling capacitor placed within 2mm. |
| 6 | IN+ | Channel A noninverting input - accepts common-mode voltages down to –0.2V for ground-referenced thresholds. |
| 7 | IN– | Channel A inverting input - differential pair input node; matched to IN+ for offset minimization. |
| 8 | N.C. | No internal connection - same as Pin 1; avoid routing signal traces to this pin. |
Key Features
| Feature | Design Value |
|---|---|
| 25ns propagation delay | Enables real-time response to fast transients in sampling circuits and line receivers without added timing margin. |
| Internal 2mV hysteresis | Eliminates need for external positive feedback resistors, reducing BOM count and PCB area in threshold detectors. |
| TTL-compatible outputs | Direct interface with legacy logic families avoids level translators or pull-up networks in industrial control I/O modules. |
| Wide input common-mode range | Supports single-supply operation with signals referenced to system ground or negative bias rails in battery-powered systems. |
| Low 350µA supply current | Permits integration of dual comparators in always-on sensor nodes where average current budget is <1mA. |
Applications
| Battery-Powered Threshold Detection | A/D Converter Input Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Slower 1.3µs propagation delay; no internal hysteresis; wider supply range (2–36V); higher 1mA supply current. | Suitable for low-speed DC monitoring but not high-speed sampling or noise-prone line reception. | Select LM393DR only when cost sensitivity outweighs speed/power requirements and external hysteresis can be added. |
| TLV3501CDR | Faster 4.5ns delay; rail-to-rail inputs; 2.7–5.5V supply; 8.5mA supply current; no internal hysteresis. | Preferred for ultra-high-speed pulse discrimination but requires external hysteresis network and consumes >24× more power. | Choose TLV3501CDR only when sub-10ns timing is mandatory and board area permits hysteresis resistors and extra decoupling. |
Compared with LM393DR and TLV3501CDR, the MAX9107ESA-T uniquely balances 25ns speed, 350µA ultra-low power, and integrated 2mV hysteresis in an SO-8 package-making it optimal for battery-operated instrumentation and noise-immune industrial threshold detection where layout simplicity and current budget are critical.

FAQ
What is the maximum supply voltage rating for the MAX9107ESA-T?
The MAX9107ESA-T has an absolute maximum supply voltage (VCC to GND) of 6V. However, its guaranteed operating range is strictly 4.5V to 5.5V per the Electrical Characteristics table. Operation outside this range may cause parametric shift or reliability degradation, and the MAX9107ESA-T is not characterized for functionality beyond ±0.5V of nominal 5V. Always maintain VCC within 4.5V–5.5V for full specification compliance.
Does the MAX9107ESA-T include an internal latch function like the MAX9109?
No, the MAX9107ESA-T does not include an internal latch. The latch feature is exclusive to the MAX9109 variant, as confirmed in the General Description and Pin Description sections. The MAX9107ESA-T's Pin 4 is labeled LE (Latch Enable) but is unused - it must be tied to GND or VCC and is not functional. This distinguishes the MAX9107ESA-T from the MAX9109 and confirms its role as a pure dual comparator without storage capability.
Can the MAX9107ESA-T operate with input voltages below ground?
Yes, the MAX9107ESA-T supports input common-mode voltages as low as –0.2V (200mV below ground), verified in the Electrical Characteristics table under "Input Voltage Range (VCMR)". This allows direct interfacing with signals referenced to ground or slightly negative bias points without clamping diodes. However, absolute minimum input voltage is –0.3V per Absolute Maximum Ratings, so sustained operation below –0.2V risks violating specifications even if not immediately destructive.
What is the output drive capability of the MAX9107ESA-T?
The MAX9107ESA-T provides TTL-compatible outputs capable of sinking up to 8mA (VOL = 0.6V max) and sourcing 100µA (VOH = 3.0V min). These values are measured under specified load conditions and ensure direct interfacing with standard 74LS and 74F logic families without external pull-ups. The output stage is not rail-to-rail but optimized for TTL logic thresholds, making the MAX9107ESA-T suitable for driving multiple logic inputs or small LEDs with appropriate current limiting.
Is the MAX9107ESA-T pin-compatible with other packages of the same part number?
Yes, the MAX9107ESA-T (SO-8) shares identical pinout and electrical behavior with the MAX9107EKA+T (SOT23-8) variant, as both implement the dual comparator configuration with N.C. on Pins 1 and 8, OUTA on Pin 2, GND on Pin 3, LE on Pin 4, VCC on Pin 5, IN+ on Pin 6, and IN– on Pin 7. This pin mapping is explicitly shown in the "Pin Configurations" diagram for MAX9107 and confirmed across ordering information tables - enabling drop-in replacement between SO and SOT23 packages when board layout allows.
