Product details
Overview
MAX901ACPE from Maxim Integrated is a high-speed, low-power quad 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 - used in high-speed A/D converter front-ends and precision threshold detection circuits.
For engineers reviewing the MAX901ACPE datasheet, MAX901ACPE pinout, MAX901ACPE application, or MAX901ACPE equivalent, this page delivers verified electrical specs, package mapping, real-world use cases, and validated alternative options for legacy design support and obsolescence mitigation.
Technical Context
The MAX901ACPE implements four independent high-gain comparators with internal pull-up logic outputs, optimized for fast decision-making in mixed-signal systems. It supports separate analog (VCC/VEE) and digital (VDD) supplies, enabling noise isolation between signal paths - critical for sampling circuits operating near analog-digital boundaries.
Unlike the latch-equipped MAX900/MAX902/MAX903, the MAX901ACPE omits latch inputs entirely, simplifying control logic in transparent-comparator applications. Its input stage operates with rail-to-rail common-mode capability down to VEE, allowing ground-referenced sensing when VEE = GND and VCC = +5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 8ns typ (5mV overdrive, CL = 15pF) - enables sub-10ns decision latency in high-speed data acquisition. |
| Power Dissipation | 105mW max per device at +5V (26.25mW/comparator) - balances speed and thermal load in dense PCB layouts. |
| Input Offset Voltage | 1–3mV (full temp range) - ensures <±3mV threshold uncertainty in precision level-detection applications. |
| Common-Mode Range | VEE − 0.1V to VCC − 2.25V - supports ground-sensing on single +5V supply with VEE = GND. |
| Output Drive | VOH ≥ 2.4V @ 1mA sink, VOL ≤ 0.4V @ 8mA source - directly interfaces standard LS-TTL and 74HC logic families. |
| Analog Supply Range | +5V to +10V (VCC) or ±5V (VCC/VEE) - accommodates both single-ended and bipolar analog signal chains. |
| Digital Supply | VDD = +5V only - requires dedicated 5V digital rail; no tolerance for 3.3V or variable digital supply. |
Pinout & Package
MAX901ACPE is housed in a 16-pin plastic DIP (dual in-line package), 0.300-inch wide body, through-hole mountable, with 0°C to +70°C operating temperature range.
| 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 analog signals up to VCC − 2.25V. |
| 3 | GND | Ground reference for digital logic and substrate - must be low-inductance connection to minimize switching noise coupling. |
| 4, 11 | LATCH (A, B) | No-connect (N.C.) - MAX901ACPE has no latch functionality; pins 4 and 11 are unconnected internally. |
| 5, 12 | OUT (A, B) | TTL-compatible open-collector outputs with internal pull-up - drive loads up to 8mA sink current. |
| 6, 13 | N.C. | No internal connection - must remain unconnected; floating or tied to GND/VCC may cause parasitic coupling. |
| 7 | VEE | Negative analog supply and substrate terminal - set to GND for single-supply operation or −5V for split-rail use. |
| 10 | VDD | +5V digital supply - powers output stage logic; must be decoupled locally with 100nF ceramic capacitor. |
| 14 | VCC | Positive analog supply - accepts +5V to +10V; sets upper common-mode limit and analog gain stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-inclusive input range | Common-mode extends to VEE - enables zero-volt threshold detection without level-shifting circuitry. |
| Low propagation delay | 8ns typical response time - supports >100MHz sampling rates in flash ADCs and high-speed data capture. |
| Separate analog/digital supplies | VCC/VEE and VDD isolated - reduces digital switching noise injection into analog comparators. |
| TTL-compatible outputs | VOH ≥ 2.4V, VOL ≤ 0.4V - eliminates need for external level translators when interfacing with 74LS/74HC logic. |
| Low power per comparator | 26.25mW max at +5V - allows integration of four comparators in thermally constrained industrial modules. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9201ACPE | Pin-for-pin compatible, same 8ns delay, but 52.5mW max power (half of MAX901ACPE). | Lower thermal load enables higher density in multi-channel designs; identical interface and timing behavior. | Preferred for new designs where power and thermal budget are constrained. |
| LM339N | Slower (1.3µs delay), no TTL outputs (open-collector), wider supply range (2–36V), no latch or dual-supply support. | Suitable for general-purpose, non-critical timing applications; lacks speed and noise isolation features. | Only acceptable where speed is not required and board space allows discrete pull-up resistors. |
Compared with MAX901ACPE, MAX9201ACPE offers identical performance with half the power dissipation and full pin compatibility, while LM339N trades speed and integrated TTL drive for broad supply flexibility and cost - making it viable only in low-frequency, low-precision contexts.

FAQ
What is the operating temperature range for MAX901ACPE?
The MAX901ACPE is rated for 0°C to +70°C ambient operation, as indicated by the 'C' suffix in its ordering code. This commercial-grade temperature range suits indoor instrumentation, test equipment, and non-automotive industrial applications where ambient thermal excursions remain within these limits. The device's electrical specifications - including propagation delay, offset voltage, and supply current - are guaranteed across this full range.
Does MAX901ACPE include latch functionality?
No, the MAX901ACPE does not include latch inputs. Unlike the MAX900, MAX902, and MAX903 variants, the MAX901ACPE omits internal latch circuitry entirely - confirmed by datasheet Note 3 and Pin Descriptions stating "Specification does not apply to MAX901." Pins 4 and 11 are marked N.C. (no connection), and no latch-related timing parameters (e.g., tpd+(D), ts, th) are specified for MAX901ACPE.
Can MAX901ACPE operate from a single +5V supply?
Yes, MAX901ACPE supports single +5V operation: configure VCC = +5V, VEE = GND, and VDD = +5V. In this mode, the input common-mode range extends from GND to +2.75V (VCC − 2.25V), enabling ground-referenced signal detection. The datasheet explicitly confirms this configuration in Figure 1B and Applications Information under "Power Supplies."
What is the maximum load capacitance supported by MAX901ACPE outputs?
MAX901ACPE maintains 8ns typical propagation delay with CL = 15pF, as tested in the Timing Characteristics table. Load capacitance beyond 15pF increases delay nonlinearly - Figure MAX900-03 toc08 shows tpd+ rising from ~8ns to ~14ns at 70pF. For reliable sub-10ns operation, keep total node capacitance ≤15pF via short traces and minimal stubs.
Is MAX901ACPE recommended for new designs?
No - Maxim explicitly states "Not Recommended for New Designs" due to discontinuation of the legacy wafer process. While MAX901ACPE remains available for existing designs and legacy support, Maxim recommends the pin-compatible MAX9201ACPE as a direct replacement offering identical speed and half the power consumption. Designers initiating new projects should evaluate MAX9201ACPE or newer alternatives.
