Product details
Overview
The MAX9201ESE+T from Maxim Integrated is a quad high-speed voltage comparator with TTL-compatible outputs, no output latches, 7ns typical propagation delay at 5mV overdrive, ±5V or +5V to +10V analog supply range, and 9mW per comparator power consumption. It serves as a precision signal-discrimination element in high-speed A/D converter front-ends and line receivers.
For engineers reviewing the MAX9201ESE+T datasheet, MAX9201ESE+T pinout, MAX9201ESE+T application, or MAX9201ESE+T equivalent, this device is selected for low-jitter threshold detection in mixed-signal systems requiring fast response, rail-to-rail input common-mode range, and separate analog/digital supply isolation.
Technical Context
The MAX9201ESE+T implements four independent bipolar comparators with active internal pullups driving TTL logic levels. Its analog inputs accept common-mode voltages down to the negative rail (VEE), enabling ground-referenced sensing under single-supply operation (VEE = GND). Each comparator features matched propagation delay (±2.5ns max skew) and operates with independent analog (VCC/VEE) and digital (VDD) supplies.
No latch circuitry is integrated-unlike the MAX9202/MAX9203-making it suitable for transparent, real-time comparison without hold functionality. Input offset voltage is 7.5mV max over temperature, and differential input impedance exceeds 5MΩ, supporting high-impedance sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 7ns typ (5mV overdrive, CL = 15pF); enables sampling of >100MHz signals with minimal timing uncertainty. |
| Analog Supply Range | +4.75V to +10.5V (VCC–VEE), including ±5V split or +5V single-supply (VEE = GND); supports flexible system-level power architecture. |
| Digital Supply | VDD = +4.75V to +5.25V only; ensures TTL-compatible output drive strength and noise margin. |
| Input Common-Mode Range | VEE – 0.1V to VCC – 2.25V; allows direct interface to ground-referenced sensors or AC-coupled sources. |
| Power Dissipation | 33mW typ (per comparator, VCC = VDD = +5V, VEE = 0V); delivers 50% lower power than legacy MAX901-series comparators. |
| Output Drive | VOH ≥ 3.0V @ 1mA sink, VOL ≤ 0.4V @ 8mA source; meets LS-TTL fan-out-4 requirements without external pullups. |
| Input Offset Voltage | 7.5mV max (–40°C to +85°C); maintains <1 LSB error in 10-bit A/D systems with 5V full-scale reference. |
Pinout & Package
MAX9201ESE+T is housed in a 16-pin narrow SO (Small Outline) package with 1.27mm pitch, JEDEC MS-012AC compliant, 10.3mm × 7.5mm body size, and exposed pad not present.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN_– | Negative input terminals for comparators A, B, C, D; referenced to VEE substrate potential. |
| 2, 7, 10, 15 | IN_+ | Positive input terminals for comparators A, B, C, D; support rail-to-rail common-mode swing. |
| 3 | GND | Digital ground return for VDD supply and TTL output stages; must be isolated from analog ground planes. |
| 4, 5, 12, 13 | OUT_ | TTL-compatible open-collector outputs with internal pullup; drive directly into LS-TTL or CMOS logic. |
| 6 | VEE | Negative analog supply and substrate connection; sets lower bound of input common-mode range. |
| 11 | VDD | +4.75V to +5.25V digital supply for output stage; decoupling capacitor required adjacent to pin. |
| 14 | VCC | +4.75V to +10.5V positive analog supply; powers input differential pair and bias circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| 7ns propagation delay | Enables accurate timing capture in high-speed data sampling circuits where sub-10ns resolution is critical. |
| Rail-to-rail input common-mode range | Supports direct interfacing to ground-referenced transducers or AC-coupled signals without level-shifting circuitry. |
| Separate analog/digital supplies | Prevents digital switching noise from coupling into analog inputs via shared supply rails or ground paths. |
| 9mW per comparator power | Reduces thermal load in dense PCB layouts and extends battery life in portable instrumentation. |
| TTL-compatible outputs with internal pullups | Eliminates need for external pullup resistors, saving board space and reducing component count in multi-comparator designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9201EUE+T | Identical electrical specs; packaged in 16-pin TSSOP (4.4mm × 5mm) instead of narrow SO (10.3mm × 7.5mm). | TSSOP offers smaller footprint and better thermal performance but requires finer-pitch PCB layout. | Select MAX9201EUE+T when board space is constrained and reflow-compatible TSSOP assembly is available. |
| LM339DR | Slower (1.3µs propagation delay), higher power (600µA per comparator), no internal pullups, wider input offset (±7mV typ). | Suitable for DC or low-frequency (<100kHz) threshold detection, not high-speed sampling or squaring. | Choose LM339DR only for cost-sensitive, non-timing-critical applications where speed and power are secondary. |
Compared with MAX9201EUE+T, the MAX9201ESE+T provides identical performance in a larger, more manufacturable SO package; compared with LM339DR, it delivers 185× faster response and 15× lower power at the cost of tighter layout and supply design requirements.

FAQ
What is the maximum analog supply voltage range supported by the MAX9201ESE+T?
The MAX9201ESE+T supports an analog supply voltage range of +4.75V to +10.5V referenced to VEE. This includes configurations such as ±5V split supplies (VCC = +5V, VEE = –5V), single +5V supply (VEE = GND), or single +10V supply (VEE = GND). Operation outside this range risks permanent damage per absolute maximum ratings.
Does the MAX9201ESE+T include output latches like the MAX9202/MAX9203?
No, the MAX9201ESE+T does not include output latches. Unlike the MAX9202 and MAX9203, which feature TTL-compatible latch inputs to hold comparator states, the MAX9201ESE+T operates in fully transparent mode - its outputs respond immediately to input changes with no storage capability. This makes the MAX9201ESE+T ideal for real-time signal conditioning where latency must be minimized.
What is the guaranteed propagation delay specification for the MAX9201ESE+T over temperature?
The MAX9201ESE+T guarantees a propagation delay of 12ns maximum over the full operating temperature range (–40°C to +85°C) at 5mV overdrive and CL = 15pF. At +25°C, typical delay is 7ns. This specification applies to both rising and falling output transitions and is measured from input crossing the offset voltage to output crossing the TTL threshold of +1.4V.
Can the MAX9201ESE+T operate from a single +5V supply?
Yes, the MAX9201ESE+T can operate from a single +5V supply by connecting VEE to GND. In this configuration, the analog input common-mode range extends from 0V (GND) to +2.75V, enabling ground-sensing applications. The digital supply VDD must still be +4.75V to +5.25V, and separate decoupling capacitors for VCC and VDD are strongly recommended to maintain noise isolation.
What is the input bias current specification for the MAX9201ESE+T at +85°C?
The MAX9201ESE+T specifies a maximum input bias current of 7.0µA over the full temperature range (–40°C to +85°C), with typical value of 50µA at +25°C. This low bias current minimizes loading errors when interfacing with high-impedance sources such as photodiode amplifiers or precision voltage dividers, preserving signal fidelity in sensitive measurement paths.
