Product details
Overview
MAX901ACSE-T from Maxim Integrated is a high-speed, low-power dual voltage comparator with differential analog inputs and TTL-compatible 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 serves in high-speed A/D converter front-ends, line receivers, and threshold detection circuits where fast response and rail-to-rail input capability are critical.
For engineers reviewing the MAX901ACSE-T datasheet, MAX901ACSE-T pinout, MAX901ACSE-T application, or MAX901ACSE-T equivalent, this page delivers verified electrical specs, package mapping, functional role in timing-critical signal discrimination, latch-free architecture distinction versus MAX900/MAX902/MAX903, and validated alternative options for legacy design support.
Technical Context
The MAX901ACSE-T implements two independent high-gain, wide-bandwidth comparators with separate analog (VCC/VEE) and digital (VDD) supply domains, enabling noise-isolated mixed-signal operation. Its input stage accepts common-mode voltages down to VEE − 0.1V, supporting ground-sensing on single +5V supplies when VEE = GND.
No internal latching circuitry is present-unlike MAX900/MAX902/MAX903-making it transparent-only with no hold functionality. Output stages drive TTL loads directly with VOH ≥ 2.4V (ISRC = 1mA) and VOL ≤ 0.4V (ISINK = 8mA), optimized for fan-out of four low-power Schottky TTL devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 8ns typical (5mV overdrive, CL = 15pF), enabling sub-10ns decision latency in sampling circuits. |
| Input Offset Voltage | 2.0mV typical (TA = +25°C), ensuring accurate threshold detection within ±2mV error band. |
| Supply Range | Analog: +5V to +10V (VEE = GND) or ±5V; Digital: +5V only-supports flexible mixed-voltage system integration. |
| Input Common-Mode Range | VEE − 0.1V to VCC − 2.25V, allowing direct ground-referenced sensing without level-shifting. |
| Power Dissipation | 18mW per comparator at +5V, balancing speed and thermal efficiency in dense PCB layouts. |
| Output Drive | TTL-compatible: VOH ≥ 2.4V (1mA source), VOL ≤ 0.4V (8mA sink), eliminating need for external level translators. |
| Operating Temperature | 0°C to +70°C, qualified for commercial-grade instrumentation and data acquisition systems. |
Pinout & Package
MAX901ACSE-T is housed in a 16-pin narrow SO (Small Outline) package with gull-wing leads, JEDEC MS-012AC compliant, 150 mil body width, 1.27mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | IN− (A, B) | Negative input terminals for comparator channels A and B-differential pair inputs accepting signals down to VEE − 0.1V. |
| 2, 9 | IN+ (A, B) | Positive input terminals for comparator channels A and B-used with IN− to determine output state based on voltage polarity. |
| 3 | GND | Digital ground reference for VDD and TTL output stage; must be tied to system DGND with low-inductance path. |
| 4, 11 | LATCH (A, B) | No-connect pins-internally unconnected; must be left floating or tied to GND per layout best practice (no latch function in MAX901). |
| 5, 12 | OUT (A, B) | TTL-compatible open-collector–like outputs driving logic-high (≥2.4V) or logic-low (≤0.4V) states directly into LS-TTL loads. |
| 6, 13 | N.C. | No internal connection; electrically isolated-must remain unconnected on PCB. |
| 7 | VEE | Negative analog supply and substrate tie-set to −5V for split supply or GND for single +5V operation. |
| 10 | VDD | +5V digital supply for output stage only; decoupling capacitor required adjacent to pin. |
| 14 | VCC | +5V to +10V positive analog supply; requires dedicated 100nF ceramic decoupling close to pin. |
Key Features
| Feature | Design Value |
|---|---|
| 8ns propagation delay | Enables reliable sampling of >100MHz input edges in A/D converter clocking and pulse-width measurement circuits. |
| Rail-to-rail input common-mode range | Supports direct interface to sensors and transducers referenced to ground or negative rails without external biasing. |
| Separate analog/digital supplies | Reduces digital switching noise coupling into analog inputs-critical for precision threshold detection in noisy environments. |
| 18mW/comparator power consumption | Minimizes self-heating in multi-channel comparator arrays, preserving offset stability across temperature. |
| TTL-compatible outputs | Drives standard LS-TTL loads directly-eliminates need for external buffer stages in digital interface designs. |

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 |
|---|---|---|---|
| MAX9201ASA+ | Pin-for-pin compatible, same 8ns delay, but 9mW/comparator (half power), wider temp range (−40°C to +85°C), no latch inputs. | Drop-in replacement for new designs requiring lower power and extended temperature operation. | Select MAX9201ASA+ when upgrading legacy MAX901ACSE-T designs to reduce thermal load and broaden environmental qualification. |
| LM319M/NOPB | Slower (80ns delay), higher power (40mW), single +5V only, no separate analog/digital supplies, no rail-to-rail input. | Suitable only for non-critical, cost-sensitive applications where speed and input flexibility are not required. | Choose LM319M/NOPB only for prototyping or low-frequency threshold detection where MAX901ACSE-T's performance advantages are unnecessary. |
Compared with MAX901ACSE-T, MAX9201ASA+ offers identical speed with half the power and extended temperature range-ideal for modern replacements-while LM319M/NOPB trades significant speed, supply flexibility, and input range for cost and availability in non-demanding applications.

FAQ
What is the maximum operating temperature range for MAX901ACSE-T?
The MAX901ACSE-T is specified for 0°C to +70°C operation (Commercial grade). It is not rated for extended temperature ranges like −40°C to +85°C; for that, the MAX901AESE-T variant must be used. Thermal derating begins above +100°C per the absolute maximum ratings table, but the device is not characterized or guaranteed beyond +70°C.
Does MAX901ACSE-T include internal latch functionality?
No, MAX901ACSE-T does not include internal latch inputs-this is a key differentiator from MAX900, MAX902, and MAX903. Pins 4 and 11 are labeled LATCH (A, B) in the pinout but are internally unconnected (N.C.) per Maxim's datasheet. The MAX901ACSE-T operates in transparent mode only, with output states changing immediately in response to input transitions.
Can MAX901ACSE-T operate from a single +5V supply?
Yes, MAX901ACSE-T supports single +5V supply operation by tying VEE to GND and applying +5V to both VCC and VDD. The input common-mode range extends to the negative rail (VEE), enabling ground-referenced sensing. However, VDD must always be +5V-no tolerance for deviation-and analog supply (VCC) may be increased up to +10V if VEE remains grounded.
What is the typical input offset voltage for MAX901ACSE-T?
The typical input offset voltage for MAX901ACSE-T is 2.0mV at TA = +25°C, with a maximum of 3.0mV across the full 0°C to +70°C operating range. This value is measured under standard test conditions (VCM = 0V, VO = 1.4V) and directly impacts threshold accuracy in precision detection applications.
Is MAX901ACSE-T still recommended for new designs?
No-Maxim explicitly states "Not Recommended for New Designs" due to discontinuation of the original wafer process. While MAX901ACSE-T remains available for legacy support and existing production, Maxim recommends the pin-compatible MAX9201ASA+ for new designs, offering identical speed with half the power dissipation and extended temperature range.
