Product details
Overview
MAX901AESE+T from Maxim Integrated is a high-speed, low-power dual voltage comparator with differential analog inputs and TTL-logic outputs, 8ns typical propagation delay at 5mV overdrive, ±5V or +5V single-supply operation, and input common-mode range extending to the negative rail. It is used in high-speed A/D converters, line receivers, and PWM circuits where fast decision-making with latch-free operation is required.
For engineers reviewing the MAX901AESE+T datasheet, MAX901AESE+T pinout, MAX901AESE+T application, or MAX901AESE+T equivalent, this page delivers verified electrical specs, package mapping, real-world use scenarios, and validated alternative options for legacy design support and obsolescence mitigation.
Technical Context
The MAX901AESE+T implements two independent high-gain, wide-bandwidth comparators with TTL-compatible open-collector outputs and internal pull-ups. Its analog supply (VCC/VEE) supports ±5V or +5V single-supply configurations, while digital supply (VDD) is fixed at +5V - enabling mixed-signal isolation in noise-sensitive applications.
No latch circuitry is integrated - unlike MAX900/MAX902/MAX903 - eliminating timing dependencies on latch-enable signals and simplifying control logic in sampling or threshold-detection paths where transparent response is mandatory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 8ns typical at 5mV overdrive - enables sub-125MHz sampling decisions in A/D front-ends. |
| Input Offset Voltage | 1–3mV over full temperature range - ensures stable threshold accuracy across -40°C to +85°C. |
| Power Dissipation | 70mW per comparator at +5V - supports low-thermal-load designs in dense PCB layouts. |
| Input Common-Mode Range | Extends to VEE − 0.1V - allows ground-referenced sensing in single-supply systems with VEE = GND. |
| Output Drive Capability | VOH = 2.4V min at 1mA source / VOL = 0.4V max at 8mA sink - directly interfaces standard TTL loads without external buffers. |
| Analog Supply Range | +5V to +10V (VCC) with VEE = GND, or ±5V (VCC/VEE) - provides flexibility for precision vs. power trade-offs. |
| Digital Supply Requirement | VDD = +5V only - mandates dedicated clean +5V rail for TTL output stage integrity. |
Pinout & Package
MAX901AESE+T is housed in a 16-pin narrow SOIC (SO) package with exposed pad, rated for -40°C to +85°C operation. Pin assignments are fully defined in Maxim's official datasheet revision 5 (2005).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | IN− (A, B) | Negative input terminals for Channel A and B - differential pair inputs referenced to VEE. |
| 2, 9 | IN+ (A, B) | Positive input terminals for Channel A and B - accept signals up to VCC − 2.25V. |
| 3 | GND | Ground reference for digital logic and output stage - must be low-inductance connection. |
| 4, 11 | LATCH (A, B) | No-connect (NC) - MAX901 has no latch function; pins are unconnected internally. |
| 5, 12 | OUT (A, B) | TTL-compatible open-collector outputs with internal pull-ups - drive standard LS-TTL loads. |
| 6, 13 | N.C. | No internal connection - must remain unconnected per datasheet. |
| 7 | VEE | Negative analog supply and substrate terminal - tied to GND for single-supply operation. |
| 10 | VDD | +5V digital supply - powers TTL output stage; separate from analog supplies. |
| 14 | VCC | Positive analog supply - accepts +5V to +10V; sets upper input common-mode limit. |
Key Features
| Feature | Design Value |
|---|---|
| 8ns propagation delay | Enables real-time discrimination of fast-rising edges in high-frequency sampling systems without added latency. |
| Separate analog/digital supplies | Allows physical and electrical isolation between noisy digital domains and sensitive analog signal paths. |
| Input range includes negative rail | Supports direct interfacing to bipolar sensors or AC-coupled signals without level-shifting circuitry. |
| TTL-compatible outputs | Drives up to four LS-TTL loads directly - eliminates need for external buffer stages in legacy logic systems. |
| 18mW/comparator power consumption | Reduces thermal load in multi-channel comparator arrays - critical for compact industrial control modules. |
Applications
| High-Speed A/D Converters | Line Receivers |
|---|---|

Use Scenario: Overvoltage/undervoltage monitoring in FPGA power rails or battery management systems. IC Role / Device Role / Timing Role: Independent dual channel detecting upper and lower thresholds on the same analog input. Use Value: 1–3mV input offset voltage guarantees repeatable trip points across temperature, reducing false alarms in safety-critical systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed dual comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9201ESA+ | Pin-for-pin compatible, same 8ns delay, but 9mW/comparator (half the power of MAX901AESE+T). | Designed for new designs; supports same supply ranges but optimized for lower thermal footprint. | Select when upgrading legacy systems or designing new boards requiring reduced power and extended lifetime. |
| LM319M/NOPB | Slower (80ns propagation delay), higher supply current (8mA), no separate VDD/VCC/VEE rails - single +5V or ±15V only. | Suitable for cost-sensitive, non-critical timing applications where speed is not limiting. | Choose only for drop-in replacement in non-speed-critical legacy repairs where MAX901AESE+T is unavailable. |
Compared with MAX901AESE+T, MAX9201ESA+ offers identical speed with half the power dissipation and active production status, while LM319M/NOPB trades significant speed and supply flexibility for broad availability and lower cost in non-demanding applications.

FAQ
Is MAX901AESE+T recommended for new designs?
No - Maxim explicitly states MAX901AESE+T is "Not Recommended for New Designs" due to discontinued wafer fabrication. It remains supported for existing designs with full datasheet access, but new projects should consider MAX9201ESA+ as the designated replacement with identical speed and half the power consumption.
What is the correct power supply configuration for MAX901AESE+T?
MAX901AESE+T requires three supplies: VCC (+5V to +10V analog positive), VEE (analog negative, typically GND for single-supply), and VDD (+5V digital only). VCC and VEE set the analog input range; VDD powers the TTL output stage. Decoupling capacitors must be placed near each supply pin.
Does MAX901AESE+T include latch functionality?
No - unlike MAX900/MAX902/MAX903, the MAX901AESE+T has no internal latch circuitry. Pins 4 and 11 are marked N.C. (no connect) in the datasheet. This makes it ideal for applications requiring immediate, transparent response to input changes without latch timing constraints.
What is the maximum input overdrive for guaranteed 8ns propagation delay?
The 8ns typical propagation delay for MAX901AESE+T is specified at 5mV input overdrive (VOD) with 15pF load and 2mA output current. At 2mV VOD, delay increases to ~12ns; at 25mV VOD, it drops to ~6ns - confirming tight correlation between overdrive and timing performance.
Can MAX901AESE+T operate from a single +5V supply?
Yes - configure VEE = GND, VCC = +5V, and VDD = +5V. The input common-mode range then extends from GND to +2.75V (VCC − 2.25V), enabling ground-sensing capability. Output VOH remains ≥2.4V, ensuring reliable TTL logic-high signaling under this configuration.
