Product details
Overview
MAX996ESD+ from Maxim Integrated is a quad micropower comparator with open-drain output stage, rail-to-rail inputs/outputs, and 120ns propagation delay. It operates from +2.5V to +5.5V single supply (or ±1.25V to ±2.75V dual supply), consumes only 48μA per comparator, and supports level translation up to 6V above VEE. It is used in battery-powered threshold detection and bipolar-to-single-ended signal conversion.
For engineers reviewing the MAX996ESD+ datasheet, MAX996ESD+ pinout, MAX996ESD+ application, or MAX996ESD+ equivalent, key selection criteria include open-drain output voltage tolerance (+6V beyond VEE), 0.5mV typical input offset, ±2.5mV internal hysteresis, rail-to-rail common-mode range (VEE −0.25V to VCC +0.25V), and 1.0pA typical input bias current.
Technical Context
The MAX996ESD+ implements four independent comparators sharing a common open-drain output architecture, each capable of sinking current while allowing external pull-up to voltages up to 6V above VEE. Its input stage features ultra-low bias current (1.0pA typ.) and extends 250mV beyond both supply rails, enabling robust operation with overdriven inputs without phase reversal.
Propagation delay remains stable at 120ns (100mV overdrive, CL = 15pF, VCC = 5V) across −40°C to +85°C, and supply current increases only marginally with switching frequency-100μA at 1MHz-due to a unique low-surge output stage that minimizes supply glitches.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.5V to +5.5V single supply; enables direct use in 3V and 5V systems without level-shifting. |
| Propagation Delay | 120ns at 100mV overdrive (CL = 15pF, VCC = 5V); ensures fast response for timing-critical zero-crossing and window detection. |
| Quiescent Current | 48μA per comparator (VCC = 2.7V, TA = +25°C); supports multi-year battery life in portable sensor nodes. |
| Input Offset Voltage | ±0.5mV typical (full common-mode range); reduces false triggering in precision threshold applications. |
| Input Bias Current | 1.0pA typical (within rails); preserves signal integrity when driving high-impedance sources like thermistors or photodiodes. |
| Open-Drain Output Voltage Range | −0.3V to +6V relative to VEE; allows safe interfacing with higher-voltage logic (e.g., 3.3V → 5V level translation). |
| Common-Mode Input Range | VEE −0.25V to VCC +0.25V; supports inputs beyond rails-critical for ground-referenced AC signals in zero-crossing detectors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad open-drain comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3704IPW | Higher supply current (85μA/comparator), slower propagation (360ns), but rail-to-rail output swing (push-pull) and wider temp range (−55°C to +125°C). | Not suitable for low-power battery systems; better for high-temp under-hood automotive use where push-pull drive is required. | Select TLV3704IPW only if push-pull output and extended temperature rating outweigh power and speed penalties. |
| LM339DR | Higher quiescent current (500μA total), much slower (1.3μs), no rail-to-rail inputs, but industry-standard pinout and wide availability. | Lacks rail-to-rail input capability and micropower operation-unsuitable for precision low-voltage or battery-critical designs. | Choose LM339DR only for legacy cost-sensitive industrial controls where speed and input range are non-critical. |
Compared with TLV3704IPW and LM339DR, MAX996ESD+ delivers 5.5× lower supply current than LM339DR and 1.8× faster response than TLV3704IPW, while uniquely supporting 6V-tolerant open-drain outputs-making it optimal for modern mixed-voltage, low-power embedded sensing.

FAQ
What is the maximum allowable voltage on the MAX996ESD+ open-drain output pin?
The MAX996ESD+ open-drain output (e.g., Pin 1/OUTD) can tolerate voltages up to +6V relative to VEE. This means when VEE = 0V (single-supply), the output may be pulled up to 6V; when VEE = −2.75V (dual supply), the absolute maximum is +3.25V. Exceeding this risks permanent damage per Absolute Maximum Ratings.
Does the MAX996ESD+ require external hysteresis for stable operation with noisy inputs?
No-the MAX996ESD+ includes ±2.5mV internal hysteresis, which prevents output oscillation on slow or noisy inputs. External hysteresis is optional and only needed when a wider switching band (e.g., >10mV) is required for noise immunity in specific applications like motor commutation feedback.
Can the MAX996ESD+ operate from a single 2.5V supply?
Yes-the MAX996ESD+ is fully specified from +2.5V to +5.5V single supply. At VCC = 2.5V, it maintains 120ns propagation delay (100mV overdrive), 48μA typical supply current per comparator, and rail-to-rail input range from −0.25V to +2.75V-making it suitable for ultra-low-voltage IoT sensor nodes.
What is the input bias current specification for MAX996ESD+ across temperature?
The MAX996ESD+ input bias current is typically 1.0pA at +25°C and remains below 10nA over the full −40°C to +85°C operating range. This ultra-low value ensures minimal loading of high-impedance sources such as pH electrodes, piezoelectric sensors, or RC timing networks.
Is the MAX996ESD+ pin-compatible with other devices in the MAX99x family?
No-MAX996ESD+ uses a 14-pin SO package (S14-4), whereas MAX992EUA-T is in 8-pin μMAX and MAX988EXK-T is in 5-pin SC70. While functional behavior aligns with MAX992/MAX988 (open-drain, same specs), physical pinout and channel count differ; PCB layout is not interchangeable across the family.
