Product details
Overview
The MAX9107ESA from Maxim Integrated is a dual, high-speed, low-power voltage comparator designed for single +5V supply systems. It delivers 25ns propagation delay with 10mV input overdrive, consumes only 350µA per comparator (1.75mW), and supports input common-mode range from −200mV to VCC−1.5V. It is used in threshold detection, A/D converter front-ends, and line receivers where TTL-compatible outputs and internal hysteresis ensure clean switching.
For engineers reviewing the MAX9107ESA datasheet, MAX9107ESA pinout, MAX9107ESA application, or MAX9107ESA equivalent, this device offers verified 25ns timing, sub-millivolt offset (≤4.0mV over temperature), integrated 2mV hysteresis, and SO-8 packaging-key selection criteria for battery-powered sensing and precision level-detection circuits.
Technical Context
The MAX9107ESA implements a bipolar comparator core with internal hysteresis (2mV) to suppress oscillation during slow input transitions. Its input stage operates rail-to-rail down to −200mV below ground and up to 1.5V below VCC, enabling direct interfacing with grounded sensors and logic-level signals.
Output stages are TTL-compatible with VOH ≥3.0V at 100µA and VOL ≤0.6V at 3.2mA, eliminating external pull-ups. Propagation delay skew is limited to 5ns between channels, and differential delay is ≤1ns-critical for matched dual-channel timing in sampling circuits and zero-crossing detectors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 25ns at 10mV overdrive - enables high-speed sampling up to ~20MHz without added latency. |
| Supply Current per Comparator | 350µA typical at +5.5V - supports ultra-low-power operation in battery-backed systems. |
| Input Offset Voltage | ≤4.0mV over −40°C to +85°C - ensures stable trip-point accuracy across industrial temperature range. |
| Input Common-Mode Range | −0.2V to VCC−1.5V - allows direct connection to ground-referenced transducers and DAC outputs. |
| Hysteresis | 2mV internal - eliminates need for external feedback resistors and prevents chatter on noisy inputs. |
| Output Compatibility | TTL - drives standard 74LS/74F logic directly without level-shifting or pull-up components. |
| Operating Supply | +4.5V to +5.5V - compatible with regulated 5V rails and tolerant of typical power-supply ripple. |
Pinout & Package
MAX9107ESA is housed in an 8-pin SO (Small Outline) package (package code S8-2), RoHS-compliant, with 1.27mm lead pitch and standard JEDEC MS-012 outline.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | N.C. | No internal connection - must be left unconnected or tied to GND per layout best practice. |
| 2 | OUTA | Channel A TTL-compatible output - sinks up to 3.2mA or sources 100µA; drives logic directly. |
| 3 | GND | Analog/digital ground reference - requires low-inductance connection to PCB ground plane. |
| 4 | N.C. | No internal connection - must be left unconnected or tied to GND. |
| 5 | VCC | Positive supply input - requires local 0.1µF ceramic decoupling capacitor placed adjacent to pin. |
| 6 | IN+ | Channel A noninverting input - accepts signals from −0.2V to VCC−1.5V; high-impedance (IB ≤350nA). |
| 7 | IN− | Channel A inverting input - matches IN+ in voltage range and bias current; differential pair input node. |
| 8 | OUTB | Channel B TTL-compatible output - electrically identical to OUTA; independent channel with matched delay. |
Key Features
| Feature | Design Value |

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 typ), higher supply current (1mA), no internal hysteresis, open-collector output requiring pull-up. | Suitable for low-speed, cost-sensitive industrial controls but not for >100kHz sampling or battery-constrained designs. | Select MAX9107ESA when 25ns timing, TTL drive, and hysteresis are required; LM393DR only where speed and power are secondary. |
| TLV3501CDR | Faster (4.5ns), rail-to-rail input, CMOS output (not TTL), higher supply current (5.3mA), requires external hysteresis. | Better for high-speed ADC triggering or RF envelope detection, but incompatible with legacy TTL loads without level translation. | Choose TLV3501CDR for sub-10ns timing needs; MAX9107ESA remains optimal for TTL-integrated, low-power, dual-channel 25ns use cases. |
Compared with LM393DR and TLV3501CDR, the MAX9107ESA uniquely combines TTL compatibility, internal hysteresis, 25ns speed, and 350µA power in a dual SO-8 package-making it the only drop-in solution for space- and power-constrained 5V systems needing guaranteed clean switching without external components.

FAQ
What is the maximum operating supply voltage for the MAX9107ESA?
The MAX9107ESA has an absolute maximum supply voltage of 6V, but its specified operating range is +4.5V to +5.5V. Operation outside this range may cause parametric degradation or damage. The MAX9107ESA is optimized for stable performance within the 5V ±5% tolerance band common in regulated industrial and embedded power supplies.
Does the MAX9107ESA require external hysteresis components?
No, the MAX9107ESA integrates 2mV of internal hysteresis, eliminating the need for external feedback resistors. This feature ensures clean output transitions even with slow-moving or noisy input signals. The MAX9107ESA's fixed hysteresis is factory-trimmed and guaranteed over temperature, simplifying layout and improving reliability compared to discrete hysteresis implementations.
Can the MAX9107ESA drive standard TTL logic loads directly?
Yes, the MAX9107ESA features TTL-compatible outputs that source ≥3.0V at 100µA and sink ≤0.6V at 3.2mA-fully compliant with 74LS and 74F logic families. No external pull-up resistors are needed, reducing component count and board area. This capability is intrinsic to the MAX9107ESA's output stage design and is verified across the full −40°C to +85°C temperature range.
What is the input common-mode voltage range of the MAX9107ESA?
The MAX9107ESA supports an input common-mode range from −0.2V to VCC−1.5V. At VCC = +5V, this translates to −0.2V to +3.5V. This extended lower limit enables direct interfacing with grounded sensors, op-amp outputs, and other signals referenced to system ground-without level-shifting circuitry. The MAX9107ESA maintains specified performance across this full range.
Is the MAX9107ESA pin-compatible with older industry-standard comparators?
The MAX9107ESA is a functional upgrade-not a pin-compatible replacement-for the MAX907. While both are dual comparators in SO-8 packages, the MAX9107ESA reassigns pins 1 and 4 as N.C. (vs. unused or differently configured pins in MAX907), and its input/output mapping differs. System redesign is required to migrate from MAX907 to MAX9107ESA; however, the MAX9107ESA offers superior speed, lower power, and integrated hysteresis.
