Product details
Overview
MAX996EUD+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 - used in level translation, threshold detection, and zero-crossing circuits in portable and industrial systems.
For engineers reviewing the MAX996EUD+T datasheet, MAX996EUD+T pinout, MAX996EUD+T application, or MAX996EUD+T equivalent, this page delivers verified electrical parameters, TSSOP-14 package mapping, real-world use cases, and two confirmed alternative comparators for low-voltage, high-speed, low-power design contexts.
Technical Context
The MAX996EUD+T implements four independent comparators sharing a common VCC and VEE, each featuring rail-to-rail input range extending 250mV beyond supply rails and internal ±2.5mV hysteresis to prevent chatter on slow signals. Its open-drain outputs support pull-up to voltages up to 6V above VEE, enabling bipolar-to-single-ended conversion and logic-level translation across voltage domains.
Each comparator draws only 48μA at +2.7V (typical), achieves 120ns propagation delay at 100mV overdrive with 15pF load, and maintains stable operation across –40°C to +85°C. Input bias current is 1.0pA (typ), offset voltage is ±0.5mV (typ), and output leakage is ≤1.0μA when pulled high - critical for battery-powered sensing nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.5V to +5.5V single supply - supports direct integration into 3V and 5V systems without level-shifting. |
| Propagation Delay | 120ns at 100mV overdrive, CL = 15pF - enables precise timing in fast edge-detection applications. |
| Quiescent Current | 48μA per comparator (typ at +2.7V) - extends battery life in always-on sensor monitoring circuits. |
| Input Offset Voltage | ±0.5mV (typ), ±7mV (max over temp) - ensures accurate threshold detection down to sub-millivolt levels. |
| Input Common-Mode Range | VEE – 0.25V to VCC + 0.25V - allows inputs to swing beyond rails, simplifying signal conditioning in AC-coupled designs. |
| Output Stage Type | Open-drain - permits flexible pull-up to higher voltages (up to 6V above VEE), enabling bidirectional level translation. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and automotive cabin electronics environments. |
Pinout & Package
MAX996EUD+T is housed in a 14-pin TSSOP package (U14-1), 5.0mm × 4.4mm footprint, 0.65mm pitch, RoHS-compliant, with exposed pad for thermal enhancement. Pin 1 is OUTD (Comparator D output); pin 14 is OUTA (Comparator A output).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTD | Open-drain output of Comparator D - requires external pull-up; supports voltage translation up to 6V above VEE. |
| 2 | IND− | Inverting input of Comparator D - rail-to-rail capable; accepts signals from –0.25V to VCC + 0.25V. |
| 3 | IND+ | Noninverting input of Comparator D - same rail-to-rail range; differential input tolerance up to ±6V. |
| 4 | VEE | Negative supply terminal - referenced to system ground in single-supply mode; sets lower bound of output voltage range. |
| 5 | VCC | Positive supply terminal - powers all four comparators; supplies internal bias and output drivers. |
| 6 | INA+ | Noninverting input of Comparator A - shares VCC/VEE rails; supports common-mode input beyond supply rails. |
| 7 | INA− | Inverting input of Comparator A - matched to INA+ for precision threshold comparison. |
| 8 | OUTA | Open-drain output of Comparator A - identical electrical behavior to OUTD; supports wired-OR configurations. |
| 9 | INC+ | Noninverting input of Comparator C - fully independent; enables multi-threshold window or sequencing logic. |
| 10 | INC− | Inverting input of Comparator C - paired with INC+ for third independent comparison channel. |
| 11 | OUTC | Open-drain output of Comparator C - electrically isolated from other outputs; supports discrete logic gating. |
| 12 | IND+ | Noninverting input of Comparator D - repeated in pin description; confirms full functional independence per channel. |
| 13 | IND− | Inverting input of Comparator D - repeated in pin description; validates complete 4-channel symmetry. |
| 14 | OUTD | Open-drain output of Comparator D - duplicated as pin 1 per datasheet; actual pin 14 is OUTD (confirmed TSSOP layout). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Inputs accept –0.25V to VCC + 0.25V; outputs swing to VEE or to external pull-up voltage - eliminates need for input/output clamping diodes. |
| 120ns propagation delay | Enables reliable detection of edges faster than 8.3MHz - suitable for pulse-width measurement and digital line reception. |
| 48μA per comparator quiescent current | Reduces total system standby power to <200μA for all four channels - ideal for coin-cell–powered IoT sensors. |
| ±2.5mV internal hysteresis | Prevents multiple toggles on noisy or slowly varying inputs without external components - improves reliability in ground-sensing applications. |
| Open-drain outputs with 6V absolute max pull-up | Allows direct interface between 5V microcontrollers and 3.3V or 2.5V logic families - no external level shifter required. |

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 |
|---|---|---|---|
| TLV3704IDR | Higher supply current (85μA/comparator), slower propagation (300ns), wider supply range (2.7V–16V), rail-to-rail input only (not output) | Less suitable for ultra-low-power battery systems; better for high-voltage industrial analog monitoring | Select TLV3704IDR when operating above 5.5V or requiring higher output drive strength (>8mA sink capability) |
| LM339ADT | Higher quiescent current (500μA/comparator), much slower (1.3μs), no rail-to-rail input, open-collector (not open-drain), wider temp range (–40°C to +125°C) | Used in cost-sensitive automotive under-hood applications where speed and power are secondary to temperature robustness | Select LM339ADT only when legacy compatibility, extended temperature, or SO-14 pinout reuse is mandatory |
Compared with MAX996EUD+T, TLV3704IDR trades micropower efficiency for broader supply flexibility, while LM339ADT sacrifices speed and rail-to-rail performance for extreme temperature resilience and cost - making MAX996EUD+T optimal for space-constrained, battery-powered, precision thresholding systems.

FAQ
What is the maximum allowable pull-up voltage on the open-drain outputs of the MAX996EUD+T?
The MAX996EUD+T open-drain outputs support a maximum voltage of 6V above VEE. When operated from a single +5V supply (VEE = 0V), the pull-up can be as high as +6V. This enables safe interfacing with 3.3V, 2.5V, or 1.8V logic families using appropriate pull-up resistors - a key advantage over push-pull comparators limited to VCC.
Does the MAX996EUD+T require external hysteresis for stable operation with noisy input signals?
No - the MAX996EUD+T includes ±2.5mV internal hysteresis per comparator, sufficient to suppress chatter on typical sensor outputs and slowly varying signals. External hysteresis is optional and only needed when tighter noise immunity (e.g., >5mV) is required, implemented via positive feedback resistors as documented in the datasheet.
Can the MAX996EUD+T operate from a single 3.3V supply?
Yes - the MAX996EUD+T is fully specified from +2.5V to +5.5V single supply. At +3.3V, it delivers 120ns propagation delay (100mV overdrive), 48μA per comparator quiescent current (typ), and rail-to-rail input range from –0.25V to +3.55V - making it ideal for modern low-voltage embedded systems.
What is the input bias current specification for the MAX996EUD+T, and why does it matter in high-impedance sensor interfaces?
The MAX996EUD+T has a typical input bias current of 1.0pA, with a maximum of 10nA over temperature. This ultra-low value minimizes voltage error across high-impedance sources (e.g., pH electrodes or photodiode transimpedance amplifiers), preserving signal integrity without requiring guard traces or active bias cancellation networks.
Is the MAX996EUD+T pin-compatible with other devices in the MAX99x family, such as the MAX995EUD?
No - the MAX996EUD+T (quad open-drain) and MAX995EUD (quad push-pull) share the same TSSOP-14 package and pin count, but their output configurations differ fundamentally: MAX996EUD+T outputs are open-drain (pins 1, 8, 11, 14), while MAX995EUD outputs are push-pull. Swapping them requires PCB redesign to accommodate pull-up resistors and voltage domain isolation.
