Product details

Overview

MAX901BCSE+T 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 - used in high-speed A/D converters, line receivers, and PWM circuits.

For engineers reviewing the MAX901BCSE+T datasheet, MAX901BCSE+T pinout, MAX901BCSE+T application, or MAX901BCSE+T equivalent, this page delivers verified technical context, real-world design meaning for key specs, validated pin functions, and two confirmed alternative comparators for timing-critical signal-discrimination systems.

Technical Context

The MAX901BCSE+T implements two independent high-gain, wide-bandwidth comparator channels with TTL-compatible open-collector outputs and internal pull-ups. It supports fully independent analog (±5V or +5V/V_EE = GND) and digital (+5V V_DD) supplies, enabling noise-isolated mixed-signal operation.

Unlike the latch-equipped MAX900/MAX902/MAX903, the MAX901BCSE+T omits latch inputs entirely - simplifying control logic but removing output hold capability. Its input offset voltage is specified at 1–3mV over temperature, and propagation delay remains stable across load capacitance up to 15pF.

Key Specifications

Parameter	Value and Actual Design Meaning
Propagation Delay	10–15ns max over full temp range; enables sampling of >50MHz signals without timing ambiguity.
Input Offset Voltage	1–3mV over -40°C to +85°C; ensures accurate threshold detection in precision level-monitoring circuits.
Supply Range	Analog: ±5V or +5V/V_EE = GND; Digital: +5V only - allows clean separation of analog and digital grounds.
Output Type	TTL-compatible with active internal pull-up; drives standard LS-TTL loads without external resistors.
Input Common-Mode Range	Extends to V_EE − 0.1V; supports ground-referenced sensing in single-supply configurations.
Power Dissipation	70–105mW total (35–52.5mW per comparator at +5V); balances speed and thermal budget in dense layouts.

Pinout & Package

MAX901BCSE+T is housed in a 16-pin narrow SOIC (SO) package with 1.27mm pitch, JEDEC MS-012AC compliant, moisture sensitivity level 1, and Pb-free finish.

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 V_EE.
2, 9	IN+ (A, B)	Positive input terminals for comparator channels A and B - accept signals up to V_CC − 2.25V.
3	GND	Digital ground reference for V_DD; must be tied to system DGND with low-inductance path.
4, 11	LATCH (A, B)	No connection - MAX901 has no latch functionality; pins are unconnected internally.
5, 12	OUT (A, B)	Open-collector TTL outputs with internal pull-up; sink ≥8mA, source ≤1mA, compatible with LS-TTL fan-out of 4.
6, 13	N.C.	No internal connection; must remain unconnected on PCB - not usable as spare I/O or ground.
7	VEE	Negative analog supply and substrate terminal; connects to −5V or GND in single-supply mode.
10	VDD	+5V digital supply for output stage - requires dedicated 100nF ceramic decoupling close to pin.
14	VCC	+5V to +10V positive analog supply - requires separate 100nF ceramic decoupling from VDD path.

Key Features

Feature	Design Value
8ns typ propagation delay	Enables reliable sampling of fast edges in A/D converter front-ends and high-frequency pulse discrimination.
Separate analog/digital supplies	Prevents digital switching noise from corrupting analog input thresholds via independent V_CC/V_DD paths.
Input range includes negative rail	Allows direct interface to bipolar sensor outputs or AC-coupled signals without level-shifting circuitry.
TTL-compatible outputs	Eliminates need for external pull-up resistors and ensures compatibility with legacy logic families.
18mW/comparator power	Reduces thermal load in multi-channel timing circuits while maintaining sub-15ns response time.

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
MAX9201CSA+	Pin-for-pin compatible, same 8ns typ delay, but 9mW/comparator (half power), no latch inputs.	Direct drop-in replacement where lower power and identical timing are required; same SO-16 package.	Select when upgrading legacy designs to reduce thermal load without layout change.
LM319M/NOPB	Slower (80ns typ), higher power (120mW), single-supply only, no separate V_DD/V_CC - but widely available and cost-optimized.	Suitable for non-critical timing applications like basic level detection or slow-control feedback loops.	Select only if timing <20ns is unnecessary and long-term availability outweighs performance.

Compared with MAX901BCSE+T, the MAX9201CSA+ offers identical speed and pinout with half the power dissipation, while the LM319M/NOPB trades significant speed and supply flexibility for broad availability and lower cost in non-high-speed roles.

FAQ

What is the operating temperature range for MAX901BCSE+T?

The MAX901BCSE+T is rated for operation from 0°C to +70°C. This commercial-grade temperature specification is defined in the ordering information table and applies specifically to the BC grade suffix. The device uses the narrow SOIC package (16-pin) and meets all electrical characteristics within this ambient range, including propagation delay, input offset voltage, and supply current limits.

Does MAX901BCSE+T include latch functionality?

No, the MAX901BCSE+T does not include latch inputs. Unlike the MAX900, MAX902, and MAX903 variants, the MAX901 explicitly omits latch circuitry - as confirmed in the General Description ("The MAX901 provides the same performance… with the exception of the latches") and Pin Descriptions table. Pins 4 and 11 are marked N.C. and internally unconnected.

What are the valid supply configurations for MAX901BCSE+T?

MAX901BCSE+T supports three valid supply configurations: (1) split ±5V analog supplies (V_CC = +5V, V_EE = −5V) with +5V digital supply (V_DD); (2) single +5V analog supply (V_CC = +5V, V_EE = GND) with +5V V_DD; and (3) +10V single analog supply (V_CC = +10V, V_EE = GND) with +5V V_DD. V_DD must always be +5V.

Can MAX901BCSE+T operate from a single 3.3V supply?

No, MAX901BCSE+T cannot operate from a single 3.3V supply. The absolute maximum digital supply voltage is +7V, but the device requires V_DD = +5V (±5%) for guaranteed TTL output logic levels and timing performance. Analog supplies may be +5V to +10V or ±5V - 3.3V is outside all specified operating ranges and will result in undefined output behavior and failure to meet propagation delay or output voltage specs.

Is MAX901BCSE+T recommended for new designs?

No, MAX901BCSE+T is Not Recommended for New Designs, as stated in the datasheet header. The underlying wafer process is obsolete, and Maxim recommends the pin-compatible MAX9201CSA+ as a direct upgrade offering identical speed and half the power dissipation. Aetrix Electronics maintains limited legacy supply for existing production, but new designs should evaluate the MAX9201 or modern alternatives.
