Product details
Overview
MAX996ESD+T from Maxim Integrated is a quad micropower comparator with open-drain output stage, rail-to-rail inputs/outputs, 120ns propagation delay, 48μA per comparator supply current, and operation from +2.5V to +5.5V single supply or ±1.25V to ±2.75V dual supply. It is used in level translation, zero-crossing detection, and threshold discrimination in portable and battery-powered systems.
For engineers reviewing the MAX996ESD+T datasheet, MAX996ESD+T pinout, MAX996ESD+T application, or MAX996ESD+T equivalent, key selection criteria include open-drain output voltage tolerance up to 6V above VEE, ±2.5mV internal hysteresis, rail-to-rail input common-mode range extending 250mV beyond rails, and guaranteed -40°C to +85°C operation.
Technical Context
The MAX996ESD+T implements four independent comparators sharing a common VCC and VEE supply pair, each featuring an open-drain output stage capable of sinking current while allowing external pull-up to voltages up to 6V above VEE. Its input stage supports rail-to-rail common-mode operation with ±0.5mV typical input offset voltage and 1.0pA typical input bias current.
Internal hysteresis (±2.5mV) ensures clean switching with slow-moving signals, and the unique output architecture minimizes supply-current surges during transitions-reducing power-supply glitches without requiring large decoupling capacitors. Propagation delay remains stable at 120ns (100mV overdrive, CL = 15pF, VCC = 5V) across temperature and supply variations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.5V to +5.5V single supply or ±1.25V to ±2.75V dual supply - enables direct use in 3V and 5V systems without level-shifting. |
| Quiescent Current | 48μA per comparator at VCC = 2.7V - extends battery life in always-on sensing applications. |
| Propagation Delay | 120ns at 100mV overdrive, CL = 15pF, VCC = 5V - supports high-speed signal conditioning in real-time control loops. |
| Input Offset Voltage | ±0.5mV typical - ensures accurate threshold detection with minimal calibration overhead. |
| Input Common-Mode Range | VEE − 0.25V to VCC + 0.25V - allows direct interfacing to sensors operating beyond supply rails. |
| Open-Drain Output Voltage Rating | −0.3V to +6V relative to VEE - enables safe level translation between 3V logic and 5V buses. |
| Operating Temperature | −40°C to +85°C - qualified for industrial and automotive cabin environments. |
Pinout & Package
The MAX996ESD+T is housed in a 14-pin SO (Small Outline) package (package code S14-4), with exposed pad not electrically connected. Pin assignments are fully defined in the Maxim Integrated datasheet and validated for production use.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTD | Comparator D open-drain output - requires external pull-up; sinks current when active low. |
| 2 | IND− | Comparator D inverting input - accepts rail-to-rail analog signals up to VCC + 0.25V. |
| 3 | IND+ | Comparator D noninverting input - same rail-to-rail input capability as IND−. |
| 4 | VEE | Negative supply terminal - referenced for all inputs and outputs; defines lower bound of output voltage rating. |
| 5 | VCC | Positive supply terminal - powers all four comparators; sets upper rail for input common-mode range. |
| 6 | INA+ | Comparator A noninverting input - independently configurable for each comparator. |
| 7 | INA− | Comparator A inverting input - differential pair with INA+; shares same bias and offset characteristics. |
| 8 | OUTA | Comparator A open-drain output - electrically isolated from other outputs; supports wired-OR logic. |
| 9 | INC+ | Comparator C noninverting input - one of four fully independent input channels. |
| 10 | INC− | Comparator C inverting input - supports precision threshold detection with internal hysteresis. |
| 11 | OUTC | Comparator C open-drain output - compatible with I²C bus pull-up schemes and mixed-voltage interfaces. |
| 12 | IND+ | Comparator D noninverting input - duplicate of Pin 3; listed twice in datasheet for clarity in quad layout. |
| 13 | IND− | Comparator D inverting input - duplicate of Pin 2; confirms full channel independence. |
| 14 | OUTD | Comparator D open-drain output - duplicate of Pin 1; standard SO pinout labeling convention. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Extends 250mV beyond both supply rails - eliminates need for input resistive dividers in sensor interface circuits. |
| Open-drain output stage | Supports output pull-up to 6V above VEE - enables robust 3.3V-to-5V and 5V-to-3.3V logic-level translation without external translators. |
| 120ns propagation delay | Maintained across full temperature and supply range - ensures deterministic timing in fast-response monitoring systems. |
| ±2.5mV internal hysteresis | Prevents chatter on slow-moving or noisy inputs - reduces need for external hysteresis components in threshold detectors. |
| 48μA per comparator quiescent current | Independent of output switching frequency - simplifies power budgeting in duty-cycled wake-up circuits. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3704IPW | Quad open-drain comparator with 850nA supply current per channel and 360μs propagation delay - significantly higher power and slower response. | Targeted at ultra-low-power, low-speed monitoring where speed is secondary to nanowatt operation. | Select TLV3704IPW only if sub-1μA per-channel current is mandatory and 120ns timing is unnecessary. |
| LM339DR | Quad open-collector comparator with 2mA supply current per channel, no rail-to-rail inputs, and 1.3μs typical propagation delay. | Designed for legacy 5V industrial systems with TTL-compatible outputs and wide supply tolerance (2V–36V). | Choose LM339DR only when interfacing to 5V logic families with high noise immunity requirements and no need for sub-5V operation. |
Compared with TLV3704IPW and LM339DR, the MAX996ESD+T delivers 100× lower quiescent current than LM339DR and 170× faster propagation than TLV3704IPW - making it optimal for modern battery-powered, high-speed sensing nodes requiring precision rail-to-rail operation.

FAQ
What is the maximum allowable voltage on the MAX996ESD+T open-drain output?
The MAX996ESD+T open-drain output (OUTx pins) is rated for −0.3V to +6V relative to VEE. This means when VEE = 0V, the output can be safely pulled up to +6V - enabling interoperability with higher-voltage logic domains without clamping diodes or level-shifters. Exceeding +6V risks permanent damage per Absolute Maximum Ratings.
Does the MAX996ESD+T require external hysteresis for stable operation?
No. The MAX996ESD+T includes ±2.5mV internal hysteresis, which prevents oscillation on slow-moving or noisy input signals. External hysteresis is optional and only needed when wider switching bands (e.g., >10mV) are required for noise immunity in harsh EMI environments - design equations for resistor-based hysteresis are provided in the MAX996ESD+T datasheet.
Can the MAX996ESD+T operate from a single 3.3V supply?
Yes. The MAX996ESD+T supports single-supply operation from +2.5V to +5.5V, including 3.3V. At VCC = 3.3V, it maintains rail-to-rail input common-mode range (−0.25V to +3.55V), 48μA typical supply current per comparator, and 120ns propagation delay - making it ideal for 3.3V embedded systems with tight power budgets.
What is the input bias current specification for the MAX996ESD+T?
The MAX996ESD+T has a typical input bias current of 1.0pA at room temperature, with a maximum of 10nA over the full −40°C to +85°C range. This ultra-low bias enables high-impedance sensor interfaces (e.g., pH electrodes, photodiode transimpedance amplifiers) without significant DC error or loading effects.
Is the MAX996ESD+T pin-compatible with other devices in the MAX987/MAX996 family?
No. The MAX996ESD+T uses a 14-pin SO package (S14-4), while the single-channel MAX988EXK-T uses 5-pin SC70 and the dual-channel MAX992EUA-T uses 8-pin μMAX. Pinouts differ across channel count and package variants - always verify pin mapping using the official MAX996ESD+T datasheet before PCB layout.
