Product details
Overview
MAX996EUD+ 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 ±2.5mV internal hysteresis - designed for level translation and bipolar-to-single-ended conversion in battery-powered sensor interfaces.
For engineers reviewing the MAX996EUD+ datasheet, MAX996EUD+ pinout, MAX996EUD+ application, or MAX996EUD+ equivalent, key selection criteria include its 14-pin TSSOP package, open-drain output capable of 6V absolute max pull-up above VEE, -40°C to +85°C industrial temperature range, and compatibility with 2.5V–5.5V single-supply or ±1.25V–±2.75V dual-supply operation.
Technical Context
The MAX996EUD+ implements four independent comparators sharing common supply rails (VCC, VEE), each featuring rail-to-rail input voltage range extending 250mV beyond both rails and internal hysteresis to prevent chatter on slow-moving signals. Its open-drain output architecture enables level-shifting across voltage domains without clamping diodes or external logic buffers.
Each comparator's output can sink up to 8mA while maintaining VOL ≤ 0.55V at 8mA (VCC = 5V, TA = –40°C to +85°C), and supports pull-up voltages up to 6V above VEE. The device avoids supply-current surges during switching, limiting dynamic ICC increase to only ~100μA at 1MHz transition frequency - critical for low-noise power-sensitive designs.

|---|---|
| Rail-to-rail input/output | Enables direct interface with sensors, DACs, and ADCs operating at supply rails - eliminates level-shifting ICs in compact designs. |
| Open-drain output stage | Supports bidirectional voltage domain bridging (e.g., 5V logic → 3.3V MCU I/O) without risk of back-powering or latch-up. |
| 120ns propagation delay | Meets timing requirements for fast-response overvoltage protection, motor commutation sensing, and digital line reception. |
| 48μA per comparator quiescent current | Reduces total system standby power to <200μA for quad-channel monitoring - critical for coin-cell–powered devices. |
| ±2.5mV internal hysteresis | Prevents oscillation on noisy or slowly varying inputs (e.g., thermistor outputs, photodiode signals) without external components. |
| No phase reversal on overdriven inputs | Guarantees predictable output polarity even when inputs exceed supply rails by 250mV - simplifies fault-tolerant design. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Quad open-collector comparator; 1.5mA/quiescent current; 300ns propagation delay; no rail-to-rail inputs; 0°C to +70°C temp range. | Higher power, slower response, narrower input range - suitable only for non-critical, low-speed industrial controls. | Select LM339DR only if legacy compatibility or extreme cost sensitivity outweighs speed, power, and input-range requirements. |
| TLV3704IPW | Quad open-drain comparator; 800nA/quiescent current; 1.5μs propagation delay; rail-to-rail inputs; 2.7V–16V supply; –40°C to +125°C. | Ultra-low power but significantly slower; wider supply range enables direct 12V sensor interfacing not supported by MAX996EUD+. | Choose TLV3704IPW for ultra-low-power battery applications where microsecond response suffices and extended temperature range is needed. |
Compared with LM339DR and TLV3704IPW, the MAX996EUD+ uniquely balances micropower operation (48μA), high speed (120ns), rail-to-rail I/O, and industrial temperature rating - making it optimal for space-constrained, battery-operated signal-conditioning circuits requiring precision timing and mixed-voltage interoperability.

FAQ
What is the maximum allowable pull-up voltage on the MAX996EUD+ open-drain outputs?
The MAX996EUD+ open-drain outputs support a maximum voltage of 6V above VEE. When VEE = 0V (single-supply mode), this permits pull-up to +6V. Exceeding this limit risks permanent damage per Absolute Maximum Ratings. Always verify VEE reference before selecting pull-up rail - e.g., with VEE = –2.5V, pull-up may reach +3.5V relative to ground.
Does the MAX996EUD+ require external hysteresis for stable operation with noisy inputs?
No - the MAX996EUD+ integrates ±2.5mV internal hysteresis, sufficient to suppress chatter on typical sensor outputs and slowly varying signals. External hysteresis resistors are optional and only needed when wider switching bands (e.g., >10mV) are required for specific noise immunity or window-detection applications.
Can the MAX996EUD+ operate from a single 3.3V supply?
Yes - the MAX996EUD+ operates from +2.5V to +5.5V single supply. At VCC = 3.3V, it maintains 120ns propagation delay (typical), 48μA per comparator supply current (typical), and full rail-to-rail input/output swing, making it ideal for modern 3.3V embedded systems.
What is the recommended PCB layout practice for minimizing noise coupling into the MAX996EUD+ inputs?
Place a 0.1μF ceramic decoupling capacitor between VCC and VEE within 2mm of the MAX996EUD+ pins. Use a solid ground plane, keep input traces short and away from noisy digital lines, and avoid routing inputs parallel to outputs or power traces. Solder directly - do not use sockets.
Is the MAX996EUD+ pin-compatible with other devices in the MAX99x family?
No - the MAX996EUD+ uses a 14-pin TSSOP package, while the single MAX988 and dual MAX992 use 5-pin SC70 and 8-pin μMAX packages respectively. Pin functions differ across package variants; always consult the MAX996EUD+ specific pin configuration diagram - not generic family drawings - for layout verification.
