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, 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 and high-speed sampling circuits.
For engineers reviewing the MAX907ESA+T datasheet, MAX907ESA+T pinout, MAX907ESA+T application, or MAX907ESA+T equivalent, key selection criteria include its guaranteed 40ns propagation delay at 5mV overdrive, internal hysteresis eliminating external feedback resistors, −0.2V to +3.5V input common-mode range at V+ = 5V, and robust short-circuit protection on all inputs/outputs.
Technical Context
The MAX907ESA+T implements a bipolar comparator core with fixed internal hysteresis (≈5mV input-referred), enabling clean switching with slow-moving or noisy input signals without external components. Its input stage supports common-mode voltages down to −0.2V (i.e., 200mV below ground) and up to V+ − 1.5V, ensuring compatibility with ground-referenced sensors and DAC outputs in single-supply systems.
Output stages are fully TTL-compatible with VOH ≥ 2.8V (ISOURCE = 100µA) and VOL ≤ 0.55V (ISINK = 3.2mA) across −40°C to +85°C, and both inputs and outputs tolerate continuous short-circuit to either supply rail. Propagation delay skew between channels is limited to 2ns, supporting precise timing alignment in dual-channel applications like window comparators or differential receivers.

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 per comparator), no internal hysteresis, open-collector outputs requiring pullups | Suitable only for low-speed DC thresholding; cannot replace MAX907ESA+T in high-frequency or low-power designs | Select only when cost is primary constraint and timing/power budgets allow significant margin degradation |
| TLV3501CDR | Faster (4.5ns typ), rail-to-rail I/O, CMOS process, but requires dual supply or level-shifting for single-supply ground-referenced inputs | Better for high-speed data acquisition, but adds complexity for simple 0–5V threshold detection | Prefer when >100MHz response needed; avoid if single +5V supply and ground-referenced inputs are mandatory |
Compared with LM393DR and TLV3501CDR, the MAX907ESA+T uniquely balances 40ns speed, 700µA ultra-low power, true single-supply operation with −0.2V input capability, and integrated hysteresis-making it irreplaceable in space-constrained, battery-operated, or noise-prone industrial sensing nodes where all three attributes are simultaneously required.

FAQ
What is the operating temperature range for MAX907ESA+T?
The MAX907ESA+T is specified for operation from −40°C to +85°C. This extended industrial temperature range ensures reliable performance in automotive cabin modules, outdoor IoT sensors, and factory-floor PLC I/O cards where ambient conditions exceed commercial limits. The "E" grade suffix in MAX907ESA+T explicitly denotes this −40°C to +85°C rating, validated per Maxim's qualification standards.
Does MAX907ESA+T require external hysteresis resistors?
No, the MAX907ESA+T incorporates fixed internal hysteresis of approximately 5mV input-referred, eliminating the need for external feedback resistors. This simplifies PCB layout, reduces component count, and avoids calculation errors associated with discrete hysteresis networks-particularly valuable in compact battery-powered designs where board space and power efficiency are critical.
Can MAX907ESA+T interface directly with a 0V-referenced sensor output?
Yes, the MAX907ESA+T supports an input common-mode range extending to −0.2V (200mV below ground), allowing direct connection to ground-referenced transducers, thermocouples, or DACs without level-shifting circuitry. This capability is confirmed in the Electrical Characteristics table under VCMR (Input Voltage Range) for the MAX907 variant at V+ = 5V.
What is the maximum capacitive load the MAX907ESA+T outputs can drive?
The MAX907ESA+T outputs are characterized up to 15pF load capacitance in the Typical Operating Characteristics plots (TOC03), with propagation delay increasing predictably beyond that point. For reliable 40ns timing, keep total trace + input capacitance ≤15pF; for heavier loads, buffer stages or lower-speed comparators should be considered. Layout best practices emphasize short traces and local decoupling to maintain signal integrity.
Is MAX907ESA+T pin-compatible with other MAX907 variants like MAX907CPA or MAX907MSA?
Yes, all MAX907 variants-including MAX907ESA+T, MAX907CPA, and MAX907MSA-share identical 8-pin SO and DIP pinouts and electrical functionality. Differences lie solely in temperature grade (−40°C to +85°C for "E", 0°C to +70°C for "C", −55°C to +125°C for "M") and packaging (SO vs. DIP). No PCB redesign is needed when upgrading from CPD to ESA+T within the same package type.
