Product details
Overview
MAX901BCSE-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 is used in high-speed A/D converters, line receivers, and PWM circuits where fast decision-making with ground-sensing capability is required.
For engineers reviewing the MAX901BCSE-T datasheet, MAX901BCSE-T pinout, MAX901BCSE-T application, or MAX901BCSE-T equivalent, key selection considerations include propagation delay consistency across temperature, latch-free architecture (distinguishing it from MAX900/MAX902/MAX903), TTL output drive strength, and dual-channel independence in mixed-supply configurations.
Technical Context
The MAX901BCSE-T implements two independent high-gain, wide-bandwidth comparators without internal latching logic-unlike the MAX900/MAX902/MAX903 family-making it suitable for transparent, real-time threshold detection. Its analog supply supports ±5V or +5V-to-+10V (VEE = GND), while digital supply VDD is fixed at +5V.
Input offset voltage is specified at 1–3mV over full temperature range (-40°C to +85°C), and output stages deliver VOH ≥ 2.4V (ISRC = 1mA) and VOL ≤ 0.4V (ISINK = 8mA), ensuring robust TTL interfacing. Propagation delay remains stable at 10–15ns over temperature with 5mV overdrive and 15pF load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 10–15ns (typ 10ns at 5mV overdrive, 15pF load): enables sampling of >50MHz signals in A/D front-ends. |
| Input Offset Voltage | 1–3mV (max over -40°C to +85°C): ensures accurate threshold detection without calibration in precision level-monitoring. |
| Supply Configuration | Separate analog (±5V or +5V to +10V) and digital (+5V) rails: isolates noise-sensitive analog paths from digital switching transients. |
| Input Common-Mode Range | VEE − 0.1V to VCC − 2.25V: supports ground-referenced sensing when VEE = GND in single-supply systems. |
| Output Drive | TTL-compatible: VOH ≥ 2.4V @ 1mA, VOL ≤ 0.4V @ 8mA - directly interfaces legacy TTL logic without level-shifting. |
| Power Dissipation | 35–55mW total (17.5–27.5mW per comparator at +5V): balances speed and thermal budget in dense PCB layouts. |
Pinout & Package
MAX901BCSE-T is supplied in a 16-pin narrow SOIC (SO) package with exposed pad (JEDEC MS-012AC), footprint compatible with industry-standard 16-SO narrow bodies (5.3mm width). Pin 1 is marked by notch or dot; device orientation follows standard SOIC top-view convention.
| 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 analog ground. |
| 2, 9 | IN+ (A, B) | Positive input terminals for comparator channels A and B - accept signal or reference for threshold comparison. |
| 3 | GND | Digital ground reference for VDD and output stage - must be low-inductance connection to minimize switching noise coupling. |
| 4, 11 | LATCH (A, B) | No-connect (NC) on MAX901 - pins are unconnected internally; must be left floating or tied to GND/VDD per layout best practice. |
| 5, 12 | OUT (A, B) | Active-pullup TTL outputs - drive loads up to 8mA sink / 1mA source; fan-out of four LS-TTL gates. |
| 6, 13 | N.C. | No internal connection - electrically isolated; recommended to leave unconnected or tie to GND for mechanical stability. |
| 7 | VEE | Analog negative supply and substrate tie - must be connected to −5V or GND depending on configuration; critical for input range and noise immunity. |
| 10 | VDD | +5V digital supply - powers output buffers and internal logic; requires dedicated 100nF ceramic decoupling near pin. |
| 14 | VCC | Analog positive supply - ranges +5V to +10V; supplies comparator core; requires separate 100nF decoupling from VDD. |
Key Features
| Feature | Design Value |
|---|---|
| 8ns typ propagation delay | Enables sub-100MHz sampling in high-speed data acquisition without added latency-induced timing skew. |
| No internal latch circuitry | Eliminates setup/hold timing constraints and latch-disable delays - simplifies control logic in real-time trigger applications. |
| Input range includes negative rail | Supports true ground-sensing in single-supply systems (VEE = GND), enabling direct interface to 0–5V sensor outputs. |
| Separate analog/digital supplies | Reduces crosstalk between noisy digital domains and precision analog thresholds - improves SNR in mixed-signal PCBs. |
| TTL-compatible outputs | Directly drives legacy TTL loads without external pull-ups or level translators - reduces BOM count and layout complexity. |
Applications
| High-Speed A/D Converters | Line Receivers |
|---|---|

Use Scenario: Differential signal recovery in RS-422/RS-485 receiver stages with noise margin >200mV. IC Role / Device Role / Timing Role: High-speed comparator converting differential bus voltage into clean TTL logic levels for controller input. Use Value: Input common-mode range down to VEE allows direct interface to −7V to +12V bus voltages when VEE = −5V, eliminating level-shifters. |
| PWM Signal Monitoring | Threshold Detectors in Sensor Interfaces |
Use Scenario: Real-time validation of duty cycle and edge timing in motor-control PWM outputs. IC Role / Device Role / Timing Role: Dual comparator detecting rising/falling edges against fixed reference to derive pulse width and period. Use Value: Matched propagation delay (<3ns inter-channel skew) ensures precise measurement of sub-50ns pulse widths in industrial inverters. |
Use Scenario: Overvoltage/undervoltage detection for Li-ion battery packs or power-rail supervision. IC Role / Device Role / Timing Role: Independent channel monitoring of two distinct voltage thresholds (e.g., 3.0V and 4.2V) on same analog rail. Use Value: 1–3mV input offset ensures trip-point accuracy within ±5mV, meeting IEC 62368-1 fault-detection tolerance requirements. |
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 |
|---|---|---|---|
| MAX9202CSE+ | Pin-for-pin compatible, 8ns typ propagation delay, 9mW/comparator (half power), no latch inputs - identical functional architecture. | Lower power enables higher density in thermally constrained modules; same timing performance preserves existing timing margins. | Select for new designs requiring drop-in replacement with improved efficiency and active lifecycle support. |
| LM319M/NOPB | Slower (80ns typ), wider supply range (±15V), no separate digital/analog rails, bipolar process - not latch-free but functionally dual-comparator. | Suitable for lower-speed industrial controls where propagation delay >50ns is acceptable and ±15V supplies are standard. | Choose only when legacy LM319 footprint compatibility is mandatory and speed is secondary to supply flexibility. |
Compared with MAX901BCSE-T, MAX9202CSE+ offers identical speed and pinout with 50% lower power, while LM319M/NOPB trades speed for ruggedness and supply range - making MAX9202CSE+ the preferred upgrade path and LM319M/NOPB a fallback for non-speed-critical ±15V systems.

FAQ
What is the operating temperature range for MAX901BCSE-T?
The MAX901BCSE-T is rated for operation from −40°C to +85°C (industrial grade). This range is confirmed in the Ordering Information table and Electrical Characteristics sections of the datasheet, where all min/max parameters are guaranteed across this full span. The 'B' grade suffix explicitly denotes the −40°C to +85°C temperature capability for the MAX901BCSE-T device.
Does MAX901BCSE-T include internal latch functionality?
No, the MAX901BCSE-T does not include internal latch inputs. Unlike the MAX900, MAX902, and MAX903, the MAX901 is explicitly defined in the General Description as having "the same performance … with the exception of the latches." Pins 4 and 11 are labeled N.C. (no connection) in the MAX901 pinout and carry no internal circuitry - confirming its latch-free architecture.
What supply voltages does MAX901BCSE-T support?
MAX901BCSE-T supports flexible analog supply configurations: ±5V (VEE = −5V, VCC = +5V) or single +5V to +10V with VEE = GND. The digital supply VDD is fixed at +5V. These ranges are specified in Absolute Maximum Ratings and Electrical Characteristics, with analog supply voltage (VCC to VEE) rated up to +12V and VDD to GND up to +7V.
Can MAX901BCSE-T operate from a single +5V supply?
Yes, MAX901BCSE-T can operate from a single +5V supply by connecting VEE to GND and VCC to +5V, while maintaining VDD at +5V. The datasheet confirms this in Figure 1B ("Single +5V Supply, Common Ground") and states the analog input common-mode range includes the negative rail - enabling ground-referenced inputs under this configuration.
Is MAX901BCSE-T still recommended for new designs?
No - the datasheet explicitly states "Not Recommended for New Designs" due to discontinuation of the wafer process. While MAX901BCSE-T remains available for legacy support, Maxim recommends the pin-compatible MAX9202CSE+ as a direct replacement offering identical speed and half the power dissipation, with active manufacturing and full technical support.
