Product details
Overview
The MAX9141ESA from Analog Devices is a single high-speed rail-to-rail input comparator with latch enable and shutdown functionality, optimized for 3V/5V systems. It delivers 40ns propagation delay, 150μA supply current per comparator at 3V, and 500μV typical offset voltage, enabling precise threshold detection in battery-powered instrumentation and line receivers.
For engineers reviewing the MAX9141ESA datasheet, MAX9141ESA pinout, MAX9141ESA application, or MAX9141ESA equivalent, key selection criteria include latch-controlled sampling timing, shutdown current reduction to 12μA, rail-to-rail input operation beyond supply rails, and CMOS/TTL-compatible push-pull output without external pullups.
Technical Context
The MAX9141ESA implements a bipolar process comparator core with internal 1.5mV hysteresis to suppress oscillation during slow input transitions. Its input stage tolerates continuous short-circuit faults to either rail and supports common-mode voltages from –0.2V to VCC + 0.2V.
The output stage is current-driven, delivering VOH = VCC – 0.3V and VOL = 0.3V at 4mA load while maintaining fast slew rate. Latch and shutdown control pins (LE, SHDN) operate with TTL-compatible logic thresholds and high-impedance inputs, enabling low-power sampling and system-level power management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 40ns at 10mV overdrive - enables sub-25MHz signal edge detection in real-time monitoring circuits |
| Supply Current | 150μA per comparator at 3V - supports multi-year operation in coin-cell–powered sensors |
| Input Offset Voltage | 0.5–2.0mV (typical 0.5mV) - ensures <10mV threshold accuracy across temperature without trimming |
| Rail-to-Rail Input Range | –0.2V to VCC + 0.2V - accepts signals below GND or above VCC, e.g., AC-coupled sensor outputs |
| Output Swing | VOL = 0.3V / VOH = VCC – 0.3V - directly drives 3.3V/5V CMOS and TTL logic without level shifters |
| Hysteresis | 1.5mV input-referred - eliminates chatter on noisy or slowly varying inputs like thermistor interfaces |
| Shutdown Current | 12–30μA - reduces system standby power by >90% when comparator is inactive |
Pinout & Package
The MAX9141ESA is housed in an 8-pin SO (Small Outline) package with 150mil body width and standard 0.050" lead pitch, compatible with automated PCB assembly and IPC-7351B land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | N.C. | No internal connection - must remain unconnected or grounded per layout guidelines |
| 2 | OUT | Comparator output - push-pull CMOS/TTL-compatible signal driving logic or ADC trigger lines |
| 3 | GND | Analog/digital ground reference - requires low-inductance connection to PCB ground plane |
| 4 | LE | Latch enable - latches output state when pulled low; transparent when high (TTL-compatible threshold) |
| 5 | SHDN | Shutdown control - disables comparator and places output in high-impedance state when low |
| 6 | IN– | Inverting input - accepts rail-to-rail analog signals; protected against ±20mA continuous fault current |
| 7 | IN+ | Noninverting input - same protection and voltage range as IN–; differential pair defines trip point |
| 8 | VCC | Positive supply - operates from 2.7V to 5.5V; requires local 0.1μF ceramic decoupling capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Latch Enable (LE) | Enables synchronous sampling of analog events with 16ns setup/hold time - critical for time-of-flight or pulse-width measurement |
| Shutdown Mode | Reduces ICC to ≤30μA and forces output high-Z - allows dynamic power gating in portable data loggers |
| Rail-to-Rail Inputs | Accepts signals from –0.2V to VCC + 0.2V - eliminates need for external level-shifting in mixed-supply systems |
| Internal Hysteresis | 1.5mV fixed input-referred hysteresis - removes requirement for external feedback resistors in noise-prone environments |
| CMOS/TTL-Compatible Outputs | VOH/VOL swing within 300mV of rails at 4mA - directly interfaces to FPGA I/O banks and microcontroller GPIOs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-power comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV7215M5X | 45ns propagation delay, 120μA supply current, no latch/shutdown, SOT23-5 package | Lacks LE/SHDN control; suited for always-on threshold detection only | Select when latch/shutdown are unnecessary and board space is constrained |
| TLV3501CD | 4.5ns propagation delay, 5.3mA supply current, rail-to-rail input, no latch/shutdown, SO-8 package | Higher speed but 35× higher power; no integrated hysteresis or fault tolerance | Select when nanosecond response is mandatory and power budget allows |

FAQ
What is the maximum supply voltage rating for the MAX9141ESA?
The MAX9141ESA has an absolute maximum supply voltage (VCC to GND) of +6V. However, its specified operating range is 2.7V to 5.5V. Operating outside the 2.7V–5.5V range may cause parametric degradation or reliability issues, even if below the 6V absolute maximum. The MAX9141ESA is not rated for continuous operation at 6V.
Does the MAX9141ESA require external pull-up resistors on its output?
No, the MAX9141ESA does not require external pull-up resistors. Its output stage is a push-pull driver capable of sourcing up to 4mA and sinking up to 4mA, with VOH = VCC – 0.3V and VOL = 0.3V under load. This design ensures full CMOS/TTL compatibility without external components, simplifying PCB layout and reducing BOM count for the MAX9141ESA.
How does the latch function of the MAX9141ESA behave during shutdown?
When SHDN is driven low, the MAX9141ESA enters shutdown mode: supply current drops to ≤30μA and the output goes high-impedance. During this state, the internal latch is disabled and cannot retain state. To capture and hold a comparison result, SHDN must be high (active mode) and LE must be pulsed low after the desired input condition is met. The MAX9141ESA latch only functions when the device is fully powered and active.
What is the input common-mode voltage range specification for the MAX9141ESA?
The MAX9141ESA specifies an input common-mode voltage range of –0.2V to VCC + 0.2V. This rail-to-rail capability allows both IN+ and IN– to accept signals extending 200mV beyond the supply rails - critical for interfacing with AC-coupled sensors, op-amp outputs, or legacy 5V systems operating with 3.3V logic. This range is guaranteed over the full –40°C to +85°C temperature range.
Can the MAX9141ESA be used in automotive applications?
The MAX9141ESA is not AEC-Q100 qualified. Only the MAX9140AAXK/V+T variant is explicitly listed as AEC-Q100 qualified in the datasheet. While the MAX9141ESA shares the same bipolar process and operates over –40°C to +85°C (E grade), it lacks formal automotive qualification testing and documentation. For automotive use, designers should select the certified MAX9140AAXK/V+T or consult Analog Devices' automotive-grade alternatives before committing the MAX9141ESA to vehicle systems.
