Product details
Overview
MAX901BCSE+ 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 - used in high-speed A/D converter front-ends and line receiver circuits.
For engineers reviewing the MAX901BCSE+ datasheet, MAX901BCSE+ pinout, MAX901BCSE+ application, or MAX901BCSE+ equivalent, this page delivers verified electrical specs, package mapping, latch-free dual-comparator architecture, thermal performance across 0°C to +70°C, and direct alternatives for legacy design continuity.
Technical Context
The MAX901BCSE+ implements two independent high-gain, wide-bandwidth comparators without internal latch circuitry - distinguishing it from the latched MAX900/MAX902/MAX903 family. Each channel features rail-to-rail input capability down to VEE (–5V), TTL-output stages with 2.4V VOH min and 0.4V VOL max, and operates with separate analog (VCC/VEE) and digital (VDD) supplies or a single +5V supply.
Its 8ns propagation delay is guaranteed under 5mV overdrive with 15pF load and 2mA output drive, while input offset voltage remains ≤3mV over full temperature range and power dissipation is 18mW per comparator at +5V - enabling precise, low-jitter threshold detection in mixed-signal timing paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 8ns typical at 5mV overdrive - enables sampling of >100MHz signals in A/D interfaces. |
| Input Offset Voltage | ≤3mV over –40°C to +85°C - ensures stable threshold accuracy across industrial temperature range. |
| Supply Configuration | Separate VCC/VEE (±5V) or single +5V with VEE = GND - supports ground-sensing in single-supply systems. |
| Output Drive | TTL-compatible: VOH ≥2.4V @ 1mA, VOL ≤0.4V @ 8mA - directly drives LS-TTL and standard logic loads. |
| Power Dissipation | 18mW per comparator at +5V - reduces thermal load in dense PCB layouts. |
| Input Common-Mode Range | VEE – 0.1V to VCC – 2.25V - allows detection of signals referenced to negative rails or ground. |
| Operating Temperature | 0°C to +70°C - qualified for commercial-grade embedded instrumentation and data acquisition. |
Pinout & Package
MAX901BCSE+ is housed in a 16-pin narrow SOIC (SO) package with 1.27mm pitch, JEDEC MS-012AC compliant, body size 10.3mm × 5.3mm × 1.75mm, moisture sensitivity level 1, and Pb-free 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 with rail-to-rail common-mode support. |
| 2, 9 | IN+ (A, B) | Positive input terminals for comparator channels A and B - accept signals up to VCC − 2.25V or down to VEE − 0.1V. |
| 3 | GND | Digital ground reference - shared return for VDD and logic-level outputs. |
| 4, 11 | LATCH (A, B) | No-connect pins - MAX901 lacks internal latch circuitry; these pins are unconnected and must be left floating or tied to GND. |
| 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. |
| 6, 13 | N.C. | No internal connection - electrically isolated; no routing or termination required. |
| 7 | VEE | Negative analog supply and substrate terminal - must be connected to –5V or GND for single-supply operation. |
| 10 | VDD | +5V digital supply - powers output stage and internal logic; not tolerant of voltages outside +4.75V to +5.25V. |
| 14 | VCC | Positive analog supply - accepts +5V to +10V; sets upper input common-mode limit and analog gain bias. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input sensing | Common-mode range includes VEE (–5V) - enables ground-referenced or negative-voltage threshold detection without level-shifting. |
| High-speed response | 8ns propagation delay with 5mV overdrive - supports accurate sampling of fast edges in data converters and pulse discriminators. |
| Low-power operation | 18mW per comparator at +5V - reduces board-level heat generation and eases thermal management in multi-channel systems. |
| TTL-compatible outputs | VOH ≥2.4V / VOL ≤0.4V with 8mA sink capability - eliminates need for external level translators when interfacing with standard logic families. |
| Flexible supply architecture | Supports ±5V split supplies or +5V single supply with VEE = GND - simplifies power design in mixed-signal applications. |
Applications
| High-Speed A/D Converter Front-End | Line Receiver for Digital Communication |

IC Role / Device Role / Timing Role: Precision voltage discriminator triggering interrupt or status flags when sensor output exceeds preset limits. Use Value: ≤3mV input offset voltage ensures consistent trip points across temperature; low power enables always-on monitoring in battery-powered nodes. |
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); requires VEE = GND only - no ±5V support. | Optimized for +3.3V/+5V single-supply systems; unsuitable for true bipolar input sensing. | Select when upgrading legacy designs for lower power and modern supply rails; verify input range compatibility. |
| LM393DR | Slower (300ns typ), no latch, wider supply range (2–36V), higher offset (7mV), no rail-to-rail input - CMOS input stage absent. | General-purpose low-speed threshold detection; cannot replace MAX901BCSE+ in >10MHz signal paths. | Use only for cost-sensitive, non-timing-critical applications where speed and precision are secondary. |
Compared with MAX901BCSE+, MAX9202ESA+ offers identical speed with half the power and modern packaging but sacrifices bipolar supply flexibility, while LM393DR provides broad voltage tolerance at the expense of speed and input precision - making MAX901BCSE+ uniquely suited for legacy high-speed, ground-sensing dual-comparator roles.

FAQ
What is the operating temperature range for MAX901BCSE+?
The MAX901BCSE+ is specified for 0°C to +70°C operation (Commercial grade). Its electrical parameters - including propagation delay, input offset voltage, and output drive - are guaranteed across this range. The 'B' grade denotes tighter initial offset (≤2mV typ at +25°C) versus 'A' grade, supporting more precise threshold applications within the commercial temperature window.
Does MAX901BCSE+ include internal latch functionality?
No, MAX901BCSE+ does not include internal latch circuitry. Unlike the MAX900, MAX902, and MAX903, the MAX901 omits latch inputs entirely - pins 4 and 11 are no-connect (N.C.) and must remain unconnected. This makes MAX901BCSE+ ideal for transparent, real-time comparison where immediate output response to input changes is required.
Can MAX901BCSE+ operate from a single +5V supply?
Yes, MAX901BCSE+ supports single +5V operation: connect VCC = +5V, VEE = GND, and VDD = +5V. In this configuration, the input common-mode range extends from GND to +2.75V, enabling ground-referenced signal detection. The device maintains its 8ns propagation delay and TTL output levels under this supply condition.
What is the maximum input overdrive voltage supported by MAX901BCSE+?
MAX901BCSE+ tolerates differential input voltages from (VEE − 0.2V) to (VCC + 0.2V) - for ±5V supplies, that is –5.2V to +5.2V. Common-mode inputs may range from VEE − 0.1V to VCC − 2.25V. Exceeding these limits risks permanent damage; note that absolute maximum ratings are stress limits, not operational conditions.
Is MAX901BCSE+ pin-compatible with other devices in the MAX900 family?
MAX901BCSE+ uses a 16-pin narrow SOIC package with unique pinout: pins 4 and 11 are N.C., unlike MAX900's latched 20-pin DIP/SO or MAX902's 14-pin SO. It is not pin-compatible with MAX900, MAX902, or MAX903. Direct replacement requires PCB layout revision - though functional equivalence exists with MAX9202ESA+ in 16-pin SOIC.
