Product details
Overview
MAX901BEPE 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 -40°C to +85°C operating temperature range. It serves as a precision threshold detector in high-speed data sampling and A/D converter front-ends.
For engineers reviewing the MAX901BEPE datasheet, MAX901BEPE pinout, MAX901BEPE application, or MAX901BEPE equivalent, this page delivers verified electrical specs, package mapping, latch-free dual-comparator functionality, thermal performance across industrial temperature range, and validated alternatives for legacy design support.
Technical Context
The MAX901BEPE implements two independent high-gain, wide-bandwidth comparators with rail-to-rail input common-mode range extending to the negative supply rail (VEE), enabling ground-sensing operation under single +5V supply. Each channel features TTL-compatible output stages with 2.4V minimum VOH and 0.4V maximum VOL at 8mA sink current.
No internal latch circuitry is present-unlike MAX900/MAX902/MAX903-making MAX901BEPE suitable for transparent, real-time comparison without hold-state control. Power consumption is 18mW per comparator at +5V, with separate analog (VCC/VEE) and digital (VDD) supply domains supporting mixed-signal noise isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 8ns typ (5mV overdrive, CL = 15pF) - enables sub-10ns decision timing for 100+ MSPS sampling systems. |
| Input Offset Voltage | 1–3 mV (full temp range) - supports accurate threshold detection within ±3mV error band over -40°C to +85°C. |
| Supply Range | Analog: +5V to +10V or ±5V; Digital: +5V only - allows flexible biasing including single-supply +5V with VEE = GND. |
| Input Common-Mode Range | VEE − 0.1V to VCC − 2.25V - includes negative rail, enabling true ground-referenced sensing in single-supply configurations. |
| Power Dissipation | 18mW per comparator at +5V - reduces thermal load in dense PCB layouts and extends reliability in sealed enclosures. |
| Output Drive | TTL-compatible: VOH ≥ 2.4V @ 1mA source, VOL ≤ 0.4V @ 8mA sink - directly interfaces with LS-TTL, 74HC, and FPGA I/O without level-shifting. |
| Input Bias Current | 4–10 µA (full temp range) - compatible with high-impedance sensor sources up to ~100kΩ without significant offset error. |
Pinout & Package
MAX901BEPE is supplied in a 16-pin plastic DIP (Dual In-line Package) with 0.3-inch body width and through-hole mounting. Pin 1 is located at the left end of the top row when viewed from the top with notch or dot oriented upward.
| 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 - referenced against IN− to determine output polarity. |
| 3 | GND | Digital ground reference for VDD and TTL output stage - must be connected to system DGND with low-inductance path. |
| 4, 11 | LATCH (A, B) | No-connect (NC) on MAX901 - pins are not internally bonded; must be left unconnected or tied to VDD/GND per layout best practice. |
| 5, 12 | OUT (A, B) | TTL-output terminals - active-high logic outputs sourcing ≥1mA / sinking ≤8mA, compatible with standard TTL fan-out. |
| 6, 13 | N.C. | No internal connection - electrically floating; recommended to leave unconnected or tie to GND for mechanical stability. |
| 7 | VEE | Negative analog supply and substrate connection - sets lower rail for analog input range; may be grounded for single-supply use. |
| 10 | VDD | +5V digital supply for output stage - must be decoupled with 100nF ceramic capacitor placed within 5mm of pin. |
| 14 | VCC | Positive analog supply (up to +10V) - powers comparator core; requires dedicated 100nF decoupling adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-inclusive input range | Accepts common-mode voltages down to VEE − 0.1V - eliminates need for level-shifting when monitoring signals referenced to ground in single-supply systems. |
| 8ns propagation delay | Guaranteed by design at 5mV overdrive - supports reliable sampling of >100MHz analog transients in high-speed instrumentation. |
| Separate analog/digital supplies | VCC/VEE and VDD isolated domains - suppresses digital switching noise from corrupting analog input thresholds in mixed-signal PCBs. |
| 18mW/comparator power | Measured at +5V supply - enables dual-channel comparison in thermally constrained modules without forced air or heatsinking. |
| TTL-compatible outputs | VOH ≥ 2.4V, VOL ≤ 0.4V - drives standard TTL loads directly, reducing BOM count and eliminating external buffer ICs. |
Applications
| High-Speed Data Sampling | A/D Converter Front-End |

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 |
|---|---|---|---|
| MAX9201BEPE | Pin-for-pin compatible; 4ns propagation delay; 9mW/comparator power; same -40°C to +85°C rating. | Delivers twice the speed and half the power vs. MAX901BEPE - preferred for new designs targeting >200MSPS sampling. | Select MAX9201BEPE when upgrading legacy systems where board space and thermal budget permit higher performance. |
| LM319N/NOPB | 15ns propagation delay; 30mW/comparator; wider supply range (±15V); no separate VDD - single-supply capable but no digital/analog isolation. | Lower speed, higher power, broader voltage tolerance - suitable for general-purpose industrial comparators where timing is non-critical. | Choose LM319N/NOPB for cost-sensitive, non-high-speed applications requiring robust ±15V operation without supply domain separation. |
Compared with MAX901BEPE, MAX9201BEPE offers superior speed and efficiency for modern high-throughput systems, while LM319N/NOPB trades performance for ruggedness and supply flexibility in legacy industrial controls - both serve distinct design priorities without claiming drop-in equivalence.

FAQ
What is the operating temperature range for MAX901BEPE?
The MAX901BEPE is rated for -40°C to +85°C ambient operation, validated across full electrical specifications including input offset voltage (1–3mV), propagation delay (10–15ns), and supply current. This industrial temperature grade ensures reliable performance in factory automation, outdoor instrumentation, and automotive under-hood environments where thermal cycling occurs.
Does MAX901BEPE include internal latch functionality?
No, MAX901BEPE does not include internal latch inputs - unlike MAX900/MAX902/MAX903, which feature dedicated LATCH pins. Pins 4 and 11 on MAX901BEPE are no-connect (N.C.) and must remain unconnected. This makes MAX901BEPE ideal for applications requiring continuous, transparent comparison without state-hold behavior.
Can MAX901BEPE operate from a single +5V supply?
Yes, MAX901BEPE supports single +5V operation: configure VEE = GND, VCC = +5V, and VDD = +5V. The input common-mode range extends to VEE − 0.1V, enabling ground-referenced signal detection. Output logic levels (VOH ≥ 2.4V, VOL ≤ 0.4V) remain fully TTL-compatible under this configuration.
What is the maximum analog supply voltage for MAX901BEPE?
The MAX901BEPE analog supply (VCC to VEE) supports up to +12V differential rating, with recommended operating range of +5V to +10V for VCC when VEE = GND. At VCC = +10V, ICC increases to ~25mA per comparator, resulting in ~125mW total dissipation - ensure adequate PCB copper area or airflow if operating near upper limits.
How does MAX901BEPE handle input overdrive conditions?
MAX901BEPE propagation delay improves with greater input overdrive: tpd+ and tpd− drop from 15ns at 2mV overdrive to 8ns at 5mV, and further to ~5ns at 25mV (per Figure 5). Designers should ensure ≥5mV overdrive in timing-critical paths to guarantee sub-10ns response, especially at temperature extremes where delay increases by ~2ns from 25°C to 85°C.
