Product details
Overview
MAX907ESA-T from Maxim Integrated is a dual high-speed ultra-low-power single-supply TTL comparator IC, featuring 40ns propagation delay (5mV overdrive), 700µA per comparator supply current (3.5mW), and rail-to-rail input range from −0.2V to V+ − 1.5V. It operates from a single +4.5V to +5.5V supply and delivers TTL-compatible outputs without external pullups-ideal for battery-powered threshold detection in portable instrumentation.
For engineers reviewing the MAX907ESA-T datasheet, MAX907ESA-T pinout, MAX907ESA-T application, or MAX907ESA-T equivalent, key selection criteria include propagation delay vs. input overdrive, internal hysteresis width (±2mV trip points), output drive capability (3.2mA sink), and SO-8 package compatibility with space-constrained PCB layouts.
Technical Context
The MAX907ESA-T implements a bipolar comparator core with built-in 4mV input-referred hysteresis (VTRIP+ = +2mV, VTRIP− = −2mV at VCM = 0V), eliminating need for external feedback resistors. Its input stage accepts common-mode voltages down to −0.2V (200mV below GND) and up to V+ − 1.5V, enabling direct interfacing with sensors operating near ground.
Output stages are fully TTL-compatible with VOH ≥ 2.8V (ISOURCE = 100µA) and VOL ≤ 0.55V (ISINK = 3.2mA), and all inputs/outputs tolerate continuous short-circuit to either supply rail. Propagation delay skew between channels is ≤2ns, supporting precise timing alignment in dual-channel sampling circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 40ns typical (5mV input overdrive); enables >10MHz sampling in A/D front-ends |
| Supply Current per Comparator | 700µA at V+ = 5V (3.5mW); supports multi-year operation on coin-cell batteries |
| Input Offset Voltage | 1–3.5mV max (−40°C to +85°C); ensures stable trip-point accuracy across industrial temperature range |
| Input Common-Mode Range | −0.2V to V+ − 1.5V; allows direct connection to transducers referenced to ground or negative bias |

Use Value: Input common-mode range includes ground, allowing direct termination to system GND; TTL outputs interface natively with MCU GPIOs. |
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 (300ns typ), higher supply current (1mA/comparator), no internal hysteresis, wider supply range (2–36V) | Suitable for low-speed, wide-voltage industrial controls but lacks precision timing and micropower operation | Select when cost is primary and speed/power are secondary; requires external hysteresis resistors |
| TLV3501CDR | Faster (4.5ns), rail-to-rail I/O, CMOS input (pA bias), but higher quiescent current (8.5mA) and no built-in hysteresis | Better for high-speed data acquisition with low-input-bias sensors, but unsuitable for battery life-critical designs | Select when nanosecond timing dominates; add external hysteresis if noise immunity required |
Compared with LM393DR and TLV3501CDR, MAX907ESA-T uniquely balances 40ns speed, 700µA ultra-low power, and factory-trimmed internal hysteresis-making it optimal for portable, timing-sensitive, and noise-prone applications where board space and battery runtime are constrained.

FAQ
What is the maximum operating temperature range for MAX907ESA-T?
The MAX907ESA-T is specified for operation from −40°C to +85°C. This extended temperature grade (denoted by the "E" suffix) ensures reliable performance in automotive cabin modules, industrial controllers, and outdoor IoT edge nodes where ambient conditions exceed commercial-grade limits. The SO-8 package maintains thermal stability across this full range without derating.
Does MAX907ESA-T support dual ±5V supplies?
No, MAX907ESA-T supports only single-supply operation from +4.5V to +5.5V. Unlike the MAX909 (which offers ±5V capability), the MAX907ESA-T lacks a dedicated V− pin and internal level-shifting circuitry for negative rails. Attempting to apply −5V to any pin violates Absolute Maximum Ratings and may cause permanent damage.
Is MAX907ESA-T pin-compatible with other devices in the MAX907/MAX908/MAX909 family?
Yes, MAX907ESA-T shares identical 8-pin SO and DIP pinouts with MAX907EPA, MAX907CPA, and MAX907CSA. All variants use the same V+, INA+, INA−, GND, INB+, INB−, OUTB, OUTA arrangement. However, MAX909 variants differ fundamentally-they include LE, QOUT, QOUT, and V− pins and are not pin-compatible.
Can MAX907ESA-T drive multiple TTL inputs directly?
Yes, MAX907ESA-T outputs can drive up to 10 standard 74LS TTL inputs (each requiring 0.4mA low-level current) while maintaining VOL ≤ 0.55V. Its 3.2mA sink capability exceeds the 4mA requirement of older 74L TTL, and its 100µA source current suffices for high-level signaling to CMOS or high-impedance logic families.
What is the purpose of internal hysteresis in MAX907ESA-T, and how wide is it?
The internal hysteresis in MAX907ESA-T provides a fixed 4mV input-referred window (VTRIP+ = +2mV, VTRIP− = −2mV at VCM = 0V) to prevent oscillation during slow or noisy input transitions. This eliminates external hysteresis components and ensures clean, chatter-free output switching-critical in threshold detection and line-receiver applications where input slew rates are low.
