Product details
Overview
MAX901BCPE+ 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 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 MAX901BCPE+ datasheet, MAX901BCPE+ pinout, MAX901BCPE+ application, or MAX901BCPE+ equivalent, this page delivers verified technical context, real-world design meaning for key specs, validated pin functions, confirmed alternatives, and supply-chain support - all grounded in the official MAX900–MAX903 datasheet (Rev. 5, 2/05).
Technical Context
The MAX901BCPE+ implements two independent high-gain, wide-bandwidth comparators with TTL-compatible open-collector outputs and internal pull-ups. Its analog supply supports ±5V or +5V-to-+10V (VEE = GND), enabling ground-referenced sensing without level-shifting.
Unlike the latch-equipped MAX900/MAX902/MAX903, the MAX901BCPE+ omits latch inputs entirely - simplifying control logic but removing output hold functionality. Propagation delay remains tightly specified at 8ns (typ) for both rising and falling edges under 5mV overdrive and 15pF load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 8ns typical (tpd+, tpd−) at 5mV overdrive, 15pF load - enables sampling of >100MHz signals in A/D front-ends. |
| Input Offset Voltage | 1–3mV (max over full temp range) - sets minimum detectable voltage difference without calibration. |
| Supply Range | Analog: ±5V or +5V to +10V (VEE = GND); Digital: +5V only - supports mixed-signal isolation or compact single-rail designs. |
| Input Common-Mode Range | VEE − 0.1V to VCC − 2.25V - allows direct sensing of signals referenced to ground when VEE = GND. |
| Output Type | TTL-compatible with internal pull-up - drives standard LS-TTL loads directly; no external resistor needed for logic-high assertion. |
| Power Dissipation | 70–105mW total (per comparator: ~35–52.5mW at +5V) - balances speed and thermal budget in dense layouts. |
| Operating Temperature | 0°C to +70°C - qualified for commercial-grade instrumentation and data-acquisition systems. |
Pinout & Package
MAX901BCPE+ is supplied in a 16-pin plastic DIP package (0.300" wide), with through-hole mounting and industry-standard lead pitch (0.100"). Pin functions are electrically validated per Maxim's official pin descriptions for MAX901.
| 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 - define threshold reference relative to IN−. |
| 3 | GND | Digital ground reference - shared return for VDD and output stage; must be low-inductance for noise immunity. |
| 4, 11 | LATCH (A, B) | No connection - MAX901 has no latch function; pins are unconnected internally (N.C.). |
| 5, 12 | OUT (A, B) | Open-collector TTL outputs - sink up to 8mA; require external pull-up or rely on internal pull-up for logic-high. |
| 6, 13 | N.C. | No connection - not bonded or routed internally; leave floating or ground per layout best practice. |
| 7 | VEE | Negative analog supply and substrate connection - set to GND for single-supply operation or −5V for split-rail. |
| 10 | VDD | +5V digital supply - powers output stage and internal logic; must be decoupled locally with 100nF ceramic. |
| 14 | VCC | Positive analog supply - ranges +5V to +10V; powers comparator core; requires separate 100nF decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| 8ns propagation delay | Enables accurate timing capture in high-speed sampling circuits without added latency compensation. |
| Dual independent comparators | Allows simultaneous threshold detection on two signal paths - e.g., upper/lower limits in alarm monitoring. |
| Ground-sensing input range | Eliminates need for input biasing networks when measuring signals referenced to system ground. |
| TTL-compatible outputs with internal pull-ups | Reduces BOM count and PCB area by removing external pull-up resistors in standard logic interfacing. |
| Separate analog/digital supplies | Minimizes digital switching noise coupling into analog decision circuitry - critical in mixed-signal systems. |
Applications
| High-Speed A/D Converters | Line Receivers |
|---|---|

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 |
|---|---|---|---|
| MAX9201CPD+ | Pin-for-pin compatible; 8ns propagation delay; 9mW/comparator (half the power of MAX901BCPE+). | Same footprint and function, but lower power enables higher density in thermally constrained designs. | Select MAX9201CPD+ for new designs requiring identical performance with improved efficiency. |
| LM319N | Slower (80ns propagation delay); wider supply range (±15V); no internal pull-ups; bipolar process. | Suitable for general-purpose industrial comparators where speed is secondary to ruggedness and supply flexibility. | Choose LM319N only if legacy compatibility or extreme supply voltage tolerance (>±10V) is mandatory. |
Compared with MAX901BCPE+, MAX9201CPD+ offers identical speed and pinout with half the power consumption, while LM319N trades speed for broader supply range and bipolar robustness - making MAX9201CPD+ the preferred upgrade path for new designs.

FAQ
What is the maximum operating supply voltage for MAX901BCPE+?
The MAX901BCPE+ supports analog supply voltages up to +12V (VCC to VEE), with absolute maximum ratings of +12V across the analog rails and +7V on the digital VDD pin. For reliable operation, use VCC/VDD = +5V and VEE = GND or −5V per the datasheet's recommended conditions. Exceeding these may cause permanent damage or parametric shift.
Does MAX901BCPE+ include latch functionality?
No, the MAX901BCPE+ does not include latch inputs - unlike the MAX900, MAX902, and MAX903. Pins 4 and 11 are explicitly designated N.C. (no connection) in the MAX901 pinout. This eliminates latch control overhead but means output states respond immediately to input changes without hold capability.
Can MAX901BCPE+ operate from a single +5V supply?
Yes, MAX901BCPE+ can operate from a single +5V supply: configure VEE = GND, VCC = +5V, and VDD = +5V. Its input common-mode range extends to VEE − 0.1V, enabling true ground-referenced sensing - a key advantage over comparators requiring input biasing above ground.
What is the typical power dissipation of MAX901BCPE+ at +5V?
At +5V supplies (VCC = VDD = +5V, VEE = GND), the MAX901BCPE+ dissipates 70–105mW total - approximately 35–52.5mW per comparator. This reflects combined analog (ICC + IEE) and digital (IDD) supply currents measured across temperature, as specified in the "Power Dissipation" row of the Electrical Characteristics table.
Is MAX901BCPE+ still recommended for new designs?
No - Maxim explicitly states "Not Recommended for New Designs" due to discontinuation of the wafer process. While MAX901BCPE+ remains available for existing designs and legacy support, Maxim recommends the pin-compatible MAX9201 series (e.g., MAX9201CPD+) for new projects, offering identical speed and half the power consumption.
