Product details
Overview
MAX901BCPE 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 serves in high-speed A/D converter front-ends and line receiver circuits requiring fast threshold detection.
For engineers reviewing the MAX901BCPE datasheet, MAX901BCPE pinout, MAX901BCPE application, or MAX901BCPE equivalent, key selection considerations include propagation delay consistency across temperature, latch-free TTL output behavior, analog supply flexibility (+5V to +10V or ±5V), and compatibility with mixed-signal PCB layouts requiring separate analog/digital ground isolation.
Technical Context
The MAX901BCPE implements two independent high-gain, wide-bandwidth comparators without internal latches-unlike the MAX900/MAX902/MAX903-making it transparent at all times with no hold functionality. Its input stage supports common-mode voltages from VEE − 0.1V to VCC − 2.25V, enabling ground-sensing operation when VEE = GND.
Each comparator draws 10–25mA ICC and 7–20mA IEE from analog supplies and 4–10mA IDD from VDD = +5V, resulting in 70–105mW total power dissipation per device at full temperature range. Output stages drive TTL loads with VOH ≥ 2.4V (ISRC = 1mA) and VOL ≤ 0.4V (ISINK = 8mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 10ns max (tpd+, tpd−) at 5mV overdrive, CL = 15pF - enables sampling of >50MHz signals without timing skew. |
| Input Offset Voltage | 1–3mV over full temperature range - ensures stable threshold accuracy in precision level-detection applications. |
| Analog Supply Range | +5V to +10V (VEE = GND) or ±5V - supports both single-rail sensor interfaces and bipolar signal conditioning. |
| Input Common-Mode Range | VEE − 0.1V to VCC − 2.25V - allows direct connection to 0V-referenced transducers without level-shifting. |
| Output Drive Capability | VOH ≥ 2.4V @ 1mA, VOL ≤ 0.4V @ 8mA - directly interfaces standard LS-TTL and 74HC logic without external pull-ups. |
| Power Dissipation | 70–105mW total - balances speed and thermal load in dense mixed-signal PCBs. |
| Supply Rejection Ratio | 100–250 µV/V - maintains offset stability despite ±5% analog supply ripple. |
Pinout & Package
MAX901BCPE is housed in a 16-pin plastic DIP package (0.300" width) with through-hole mounting and industry-standard lead pitch. Pin functions are validated per Maxim's official pin configuration diagram 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 referenced to internal offset. |
| 2, 9 | IN+ (A, B) | Positive input terminals for comparator channels A and B - accept signals up to VCC − 2.25V with VEE − 0.1V lower bound. |
| 3 | GND | Digital ground reference for VDD and output stage - must be isolated from analog ground in split-supply layouts. |
| 4, 11 | LATCH (A, B) | No-connect pins - internally unconnected; must be left floating or tied to GND per layout guidelines (no latch function on MAX901). |
| 5, 12 | OUT (A, B) | TTL-compatible open-collector outputs with internal pull-up - drive standard logic loads without external resistors. |
| 6, 13 | N.C. | No internal connection - electrically inactive; no routing or termination required. |
| 7 | VEE | Negative analog supply and substrate tie - grounded for single-supply operation; −5V for bipolar mode. |
| 10 | VDD | +5V digital supply for output stage - fixed voltage requirement; not adjustable. |
| 14 | VCC | Positive analog supply - configurable from +5V to +10V, defining upper input common-mode limit. |
Key Features
| Feature | Design Value |
|---|---|
| 8ns typ propagation delay | Enables real-time discrimination of sub-100MHz analog transitions in data acquisition and clock recovery paths. |
| No internal latch circuitry | Eliminates setup/hold timing constraints and latch-disable delays - simplifies control logic in streaming comparator applications. |
| Separate analog/digital supplies | Allows AGND/DGND separation to prevent digital noise coupling into sensitive analog thresholds. |
| Input range includes negative rail | Supports direct interfacing to 0V-referenced sensors (e.g., current shunts, thermocouples) without biasing networks. |
| TTL-compatible outputs | Drives four LS-TTL loads directly - reduces BOM count and board space versus buffered or level-shifted alternatives. |
Applications
| High-Speed A/D Converter Front-End | Line Receiver for Digital Communication |

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 |
|---|---|---|---|
| MAX9201CPE+ | Pin-for-pin compatible, same 8ns typ delay, but 9mW/comparator (half power vs. MAX901BCPE's 18mW). | Lower thermal load enables higher density in compact industrial controllers; requires identical layout but reduced decoupling capacitance. | Select MAX9201CPE+ for new designs prioritizing power efficiency and long-term supply continuity. |
| LM319N | Slower (80ns typ delay), wider supply range (±15V), no separate digital/analog supplies, no latch inputs. | Suitable for general-purpose industrial threshold detection where speed <1MHz suffices and cost is primary constraint. | Choose LM319N only for legacy repair or non-critical timing applications where 8ns performance is unnecessary. |
Compared with MAX901BCPE, MAX9201CPE+ delivers identical speed with half the power and active Maxim production support, while LM319N trades significant speed for broader voltage tolerance and commodity availability - making MAX9201CPE+ the preferred upgrade path for performance-sensitive designs.

FAQ
What is the maximum operating temperature range for MAX901BCPE?
The MAX901BCPE is rated for 0°C to +70°C ambient operation, as indicated by the 'B' grade suffix and 'C' temperature code in its ordering part number. This commercial-grade rating aligns with its intended use in non-automotive, non-military instrumentation and communication equipment where extended temperature coverage is not required. The device remains fully specified across this range for all key parameters including propagation delay, input offset voltage, and output drive capability.
Does MAX901BCPE include internal latch functionality?
No, the MAX901BCPE does not include internal latch inputs - unlike the MAX900, MAX902, and MAX903. Pins 4 and 11 are designated N.C. (no connect) in the official pinout, and the datasheet explicitly states "The MAX901 provides the same performance as the MAX900/MAX902/MAX903 with the exception of the latches." This makes MAX901BCPE ideal for applications requiring continuous, transparent comparison without state-holding behavior.
Can MAX901BCPE operate from a single +5V supply?
Yes, MAX901BCPE supports single-supply operation with VEE = GND and VCC = +5V, while maintaining full input common-mode range from 0V to +2.75V. The analog input stage is designed to function correctly under this configuration, and the TTL outputs remain fully compliant. However, VDD must still be supplied at +5V independently, as it powers the output buffer stage and is not internally derived from VCC.
What is the recommended power supply decoupling for MAX901BCPE?
Maxim recommends placing 100nF ceramic decoupling capacitors as close as possible to each power pin: one between VCC and VEE, one between VDD and GND, and a shared 10µF bulk capacitor near the device. Separate analog (VCC/VEE) and digital (VDD/GND) decoupling paths are mandatory to suppress noise coupling - especially critical given the device's 1GHz+ gain-bandwidth product and sensitivity to supply-induced oscillation.
Is MAX901BCPE pin-compatible with other devices in the MAX900 family?
No, MAX901BCPE is not pin-compatible with MAX900, MAX902, or MAX903. It uses a 16-pin DIP package with distinct pin assignments: pins 4 and 11 are N.C. (vs. active LATCH inputs on other variants), and channel count differs (dual vs. quad). Attempting direct replacement would result in incorrect signal routing and functional failure. Always verify pin mapping against the specific device's datasheet diagram before board design or substitution.
