Product details
Overview
MAX901AEPE from Maxim Integrated is a high-speed, low-power dual voltage comparator with differential analog inputs and TTL-logic outputs. It delivers 8ns typical propagation delay at 5mV overdrive, consumes 18mW per comparator at +5V, and supports separate analog/digital supplies (±5V or +5V to +10V analog, +5V digital). It is used in high-speed A/D converters, line receivers, and PWM circuits where fast threshold detection is required.
For engineers reviewing the MAX901AEPE datasheet, MAX901AEPE pinout, MAX901AEPE application, or MAX901AEPE equivalent, key selection considerations include its -40°C to +85°C operating range, 16-pin plastic DIP package, absence of latch inputs (distinguishing it from MAX900/MAX902/MAX903), and compatibility with ground-sensing single-supply operation.
Technical Context
The MAX901AEPE implements two independent high-gain, wide-bandwidth comparators with rail-to-rail input common-mode range extending to the negative supply rail. Its TTL-compatible outputs drive up to four low-power Schottky TTL loads without external pull-ups, and internal active pull-ups eliminate need for external resistors.
Unlike the quad MAX900 or MAX903, the MAX901AEPE contains only two comparators and omits latch functionality entirely-confirmed by datasheet Note 3 and Pin Descriptions table. It operates with flexible supply configurations: split ±5V, single +5V (VEE = GND), or single +5V to +10V analog supply with VEE grounded.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 8ns typical at 5mV overdrive - enables sampling of >100MHz signals in A/D front-ends. |
| Power Dissipation | 18mW per comparator at +5V - reduces thermal load in dense mixed-signal PCBs. |
| Input Common-Mode Range | Includes negative rail (VEE − 0.1V to VCC − 2.25V) - supports ground-referenced sensing with single +5V supply. |
| Output Type | TTL-compatible with internal pull-up - eliminates external pull-up resistors and saves board space. |
| Supply Flexibility | Analog: +5V to +10V or ±5V; Digital: +5V only - simplifies power architecture in systems with shared or isolated rails. |
| Input Offset Voltage | 1mV min / 3mV max over full temperature - ensures stable threshold accuracy across industrial environments. |
| Operating Temperature | -40°C to +85°C - qualified for industrial and automotive under-hood applications. |
Pinout & Package
MAX901AEPE is housed in a 16-pin plastic DIP package (0.300" wide), with through-hole mounting and standard DIP footprint compatibility.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | IN− (A, B) | Negative input terminals for comparator channels A and B - differential pair inputs accepting rail-to-rail common-mode signals. |
| 2, 9 | IN+ (A, B) | Positive input terminals for comparator channels A and B - referenced against IN− to determine output state transition. |
| 3 | GND | Digital ground reference - serves as return path for VDD and logic-level outputs; must be low-inductance connection. |
| 4, 11 | LATCH (A, B) | No connection - pins are unconnected internally (N.C.), confirming absence of latch function per datasheet Note 3. |
| 5, 12 | OUT (A, B) | TTL-compatible open-collector outputs with internal pull-up - drive standard TTL loads directly; no external pull-up required. |
| 6, 13 | N.C. | No connection - not bonded or connected internally; must remain unconnected on PCB. |
| 7 | VEE | Negative analog supply and substrate terminal - tied to −5V in split-supply mode or GND in single-supply mode. |
| 10 | VDD | +5V digital supply - powers output stage and internal logic; must be decoupled locally with 100nF ceramic capacitor. |
| 14 | VCC | Positive analog supply - accepts +5V to +10V; sets upper input common-mode limit and output swing headroom. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Extends to VEE − 0.1V, enabling ground-sensing operation with single +5V supply and no level-shifting circuitry. |
| 8ns propagation delay | Supports real-time discrimination of fast edges in high-speed data acquisition and clock recovery paths. |
| Internal TTL output pull-ups | Eliminates need for four external 1–5kΩ pull-up resistors, reducing BOM count and layout complexity. |
| Separate analog/digital supplies | Allows isolation of noisy digital VDD from sensitive analog VCC/VEE domains, improving noise immunity in mixed-signal systems. |
| −40°C to +85°C operation | Validated performance across extended industrial temperature range without derating or external compensation. |
Applications

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 |
|---|---|---|---|
| MAX9201EPE+ | Pin-for-pin compatible, same 8ns delay, but 9mW/comparator (half power); includes latch inputs. | Latch capability adds control flexibility in sampled-data systems; lower power eases thermal design. | Select MAX9201EPE+ when latch functionality is needed and newer-generation sourcing is acceptable. |
| LM319N | Slower (80ns delay), higher power (30mW), no internal pull-ups, wider supply range (±15V), no latch. | Suitable for general-purpose industrial comparators where speed is secondary to ruggedness and supply flexibility. | Choose LM319N only if legacy design reuse or extreme supply voltage tolerance (+30V total) is mandatory. |
Compared with MAX901AEPE, the MAX9201EPE+ offers identical speed and pinout with halved power and added latching, while the LM319N trades speed and integration for broader supply range and legacy availability-making MAX901AEPE optimal for cost-sensitive, high-speed, latch-free industrial designs.

FAQ
What is the maximum operating supply voltage for MAX901AEPE?
The MAX901AEPE supports analog supply voltage (VCC to VEE) up to +12V and digital supply (VDD to GND) up to +7V. In practice, VCC is typically +5V to +10V, VEE is −5V or GND, and VDD is fixed at +5V. Absolute maximum ratings are stress limits only and do not imply functional operation beyond specified conditions.
Does MAX901AEPE have latch inputs like other devices in the MAX900 family?
No, MAX901AEPE does not include latch inputs. Datasheet Note 3 explicitly states that latch specifications do not apply to MAX901, and Pin Descriptions confirm pins 4 and 11 are N.C. This distinguishes MAX901AEPE from MAX900/MAX902/MAX903, which feature dedicated latch control per channel.
Can MAX901AEPE operate from a single +5V supply?
Yes, MAX901AEPE can operate from a single +5V supply by connecting VEE to GND. Its input common-mode range includes the negative rail, allowing ground-referenced input signals. VCC = +5V, VEE = GND, and VDD = +5V satisfies all supply requirements and enables rail-to-rail input sensing.
What is the typical power dissipation of MAX901AEPE at +5V?
The typical power dissipation of MAX901AEPE is 18mW per comparator at +5V, totaling 36mW for both channels. This value is confirmed in the General Description and Electrical Characteristics tables, and remains stable across the −40°C to +85°C operating range per typical curves.
Is MAX901AEPE recommended for new designs?
No, MAX901AEPE is Not Recommended for New Designs per Maxim's official notice. The underlying wafer process is obsolete. While fully functional and supported for existing users, Aetrix recommends evaluating the pin-compatible MAX9201EPE+ as a modern replacement offering identical speed and half the power consumption.
