Product details
Overview
MAX901ACSE+T from Maxim Integrated is a high-speed, low-power dual voltage comparator IC 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 is used in high-speed A/D converter front-ends, line receivers, and PWM timing circuits where fast decision-making with minimal power is 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, real-world use cases, and validated alternative options - all grounded in the official Maxim MAX900–MAX903 family datasheet (Rev. 5, Feb 2005).
Technical Context
The MAX901ACSE+T implements two independent high-gain, wide-bandwidth comparators with TTL-output stages optimized for fan-out of four LS-TTL loads. Its analog supply supports flexible configurations: ±5V split-rail or +5V to +10V single-supply with VEE grounded, while digital supply (VDD) is fixed at +5V.
No internal latch circuitry is present - unlike MAX900/MAX902/MAX903 - making it functionally distinct in timing-critical transparent-compare applications. Input offset voltage is 0.5–2.0mV (typ), and output switching thresholds align precisely with TTL logic levels (VOH ≥ 2.4V, VOL ≤ 0.4V at specified loads).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 8ns typical at 5mV overdrive - enables sampling at >100MHz effective rates in A/D interfaces. |
| Supply Configuration | Separate analog (VCC/VEE) and digital (VDD) rails or single +5V analog supply - supports mixed-signal isolation. |
| Input Common-Mode Range | Extends to VEE (negative rail) - allows ground-referenced sensing in single-supply systems. |
| Power Dissipation | 18mW per comparator at +5V - balances speed and thermal efficiency in dense layouts. |
| Output Compatibility | TTL-logic outputs with active internal pull-ups - drives standard LS-TTL without external resistors. |
| Input Offset Voltage | 0.5–2.0mV (typ) - ensures accurate threshold detection in precision level-monitoring applications. |
| Operating Temperature | 0°C to +70°C - qualified for commercial-grade industrial control and instrumentation. |
Pinout & Package
MAX901ACSE+T is supplied in a 16-pin narrow SOIC (SO) package (JEDEC MS-012AA), 3.9mm body width, 1.27mm pitch, RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | IN− (A, B) | Negative input terminals for comparator channels A and B - differential pair inputs referenced to internal offset. |
| 2, 9 | IN+ (A, B) | Positive input terminals for comparator channels A and B - accept signals within VEE −0.1V to VCC −2.25V. |
| 3 | GND | Ground reference for digital logic and substrate - must be low-inductance connection for stable TTL output switching. |
| 4, 11 | LATCH (A, B) | No internal connection - pins are unconnected (N.C.) and must remain floating or tied to GND/VDD per layout best practice. |
| 5, 12 | OUT (A, B) | TTL-compatible open-collector outputs with internal pull-up - drive logic-high at ≥2.4V, logic-low at ≤0.4V under 8mA sink. |
| 6, 13 | N.C. | No internal connection - electrically isolated; no routing or termination required. |
| 7 | VEE | Negative analog supply and substrate terminal - sets lower rail for analog input range; grounded in single-supply mode. |
| 10 | VDD | +5V digital supply - powers TTL output stage and internal logic; not tolerant of voltages outside +4.75V to +5.25V. |
| 14 | VCC | Positive analog supply - accepts +5V to +10V (single-supply) or +5V (split-rail); defines upper input common-mode limit. |
Key Features
| Feature | Design Value |
|---|---|
| 8ns propagation delay | Enables clean, jitter-free sampling in >100MHz data acquisition paths without added hysteresis or external conditioning. |
| Input range includes negative rail | Permits direct interface to ground-referenced sensors (e.g., current shunts, thermocouples) without level-shifting circuitry. |
| TTL-compatible outputs | Drives standard LS-TTL loads directly - eliminates need for external pull-up resistors or buffer stages in digital interfacing. |
| Flexible analog supply | Supports both ±5V and +5V-to-+10V operation - simplifies power architecture in mixed-signal systems with shared or isolated rails. |
| Low 18mW/comparator power | Reduces thermal load in multi-channel comparator arrays - critical for compact PCBs in automated test equipment. |
Applications
| High-Speed A/D Converters | Line Receivers |
|---|---|

Use Value: 0.5mV typical input offset enables <±5mV detection accuracy - sufficient for ±1% supply tolerance monitoring at 5V nominal. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9202ESA+ | Pin-for-pin compatible, same 8ns delay, but 9mW/comparator (half power), no latch inputs - identical functional scope to MAX901. | Drop-in replacement for new designs requiring lower power and extended lifecycle support. | Select when upgrading legacy MAX901ACSE+T designs to reduce thermal load and secure long-term supply. |
| LM319M/NOPB | Slower (80ns delay), higher power (40mW), wider supply range (±15V), no TTL outputs - requires external pull-ups and level translation. | Suitable only where speed is non-critical and bipolar supplies dominate; not interchangeable in timing-sensitive circuits. | Choose only for cost-sensitive, low-frequency comparator needs where MAX901ACSE+T's speed and TTL drive are unnecessary. |
Compared with MAX901ACSE+T, MAX9202ESA+ offers identical functionality at half the power and active production status, while LM319M/NOPB trades speed and integration for ruggedness and supply flexibility - making MAX9202ESA+ the preferred upgrade path for performance-critical applications.

FAQ
What is the operating temperature range for MAX901ACSE+T?
The MAX901ACSE+T is rated for 0°C to +70°C ambient operation (Commercial grade). This range is confirmed in the Maxim ordering information table and applies specifically to the AC temperature suffix. It is not rated for extended industrial temperatures (−40°C to +85°C), which require the AE/BE variants like MAX901AESE.
Does MAX901ACSE+T include internal latch functionality?
No, MAX901ACSE+T does not include internal latch circuitry. The datasheet explicitly states "The MAX901 provides the same performance as the MAX900/MAX902/MAX903 with the exception of the latches." Pins 4 and 11 are labeled N.C. (no connection) in the MAX901 pinout - confirming absence of latch inputs in this variant.
What supply voltages does MAX901ACSE+T support?
MAX901ACSE+T supports dual supplies (VCC = +5V, VEE = −5V, VDD = +5V) or single +5V analog supply (VEE grounded, VCC = +5V). The analog supply range extends to +10V with VEE grounded, but VDD must remain at +5V ±5%. These configurations are validated in the Electrical Characteristics tables and Applications Information section.
Is MAX901ACSE+T pin-compatible with other MAX900-series devices?
No - MAX901ACSE+T uses a 16-pin narrow SOIC package with unique pin assignments (e.g., N.C. on pins 4/11/6/13), differing from the 20-pin MAX900, 14-pin MAX902, and 8-pin MAX903. It is not physically or electrically pin-compatible with other members of the MAX900–MAX903 family.
What is the typical input offset voltage for MAX901ACSE+T?
The typical input offset voltage for MAX901ACSE+T is 2.0mV at +25°C, with a maximum of 4.0mV over temperature (0°C to +70°C). This value is specified in the "ELECTRICAL CHARACTERISTICS" table under "MAX900A/MAX901A" conditions and directly impacts threshold accuracy in precision detection applications.
