Product details
Overview
LM2901N/SL65262 from Texas Instruments is a quad differential voltage comparator IC designed for single-supply operation across industrial and automotive systems. It features 2 V to 30 V supply range, 0.8 mA typical supply current, 2 mV typical input offset voltage, open-collector outputs compatible with TTL/MOS/CMOS, and operates from –40°C to 125°C - enabling use in battery monitoring, power rail supervision, and overvoltage detection circuits.
For engineers reviewing the LM2901N/SL65262 datasheet, LM2901N/SL65262 pinout, LM2901N/SL65262 application, or LM2901N/SL65262 equivalent, key selection criteria include its ground-sensing input capability, ±36 V differential input tolerance, low input bias current (25 nA typ), and compatibility with wired-AND logic configurations in multi-threshold detection systems.
Technical Context
The LM2901N/SL65262 implements four independent comparators with PNP Darlington-pair inputs, enabling high DC gain and low input bias current while supporting common-mode input down to ground. Its open-drain NPN output stage allows flexible pull-up configuration and logic-level translation across voltage domains.
It operates over a wide supply range (2 V to 30 V) with supply-current independence, supports dual-supply operation (±1 V to ±15 V), and maintains functional integrity up to 125°C junction temperature - making it suitable for harsh-environment signal conditioning where precision thresholding and robustness are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2 V to 30 V (single supply); enables direct interface with 3.3 V, 5 V, 12 V, and 24 V rails without level-shifting circuitry |
| Input Offset Voltage | 2 mV typical (7 mV max); ensures accurate threshold detection with minimal hysteresis design overhead |
| Input Bias Current | 25 nA typical; minimizes loading on high-impedance sensor or reference sources |
| Common-Mode Input Range | 0 V to VCC – 1.5 V; supports ground-referenced sensing and rail-to-rail input monitoring |
| Output Type | Open-collector; permits wired-AND logic, mixed-voltage interfacing, and programmable sink current up to 20 mA |
| Response Time | 0.3 μs (TTL-level step); enables fast edge detection in pulse-width monitoring and fault-response circuits |
| Operating Temperature | –40°C to 125°C; qualified for under-hood automotive and industrial control environments |
Pinout & Package
LM2901N/SL65262 is packaged in a 14-pin plastic DIP (PDIP) with body size 19.30 mm × 6.40 mm, optimized for through-hole prototyping and legacy industrial PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1IN+, 2IN+, 3IN+, 4IN+ | Positive input of comparator 1–4 | Differential sense node for each comparator; accepts signals from 0 V to VCC – 1.5 V |
| 1IN−, 2IN−, 3IN−, 4IN− | Negative input of comparator 1–4 | Reference or feedback node; same common-mode range as positive inputs |
| 1OUT, 2OUT, 3OUT, 4OUT | Open-collector output of comparator 1–4 | Sinks current when IN+ > IN− + VIO; requires external pull-up for logic-high state |
| VCC | Positive supply pin | Single supply connection (2 V–30 V); powers all four comparators and internal bias circuitry |
| GND | Ground reference | Return path for supply and output sink current; defines 0 V reference for all inputs and outputs |
| Pins 5, 7, 9, 11, 12 | No connect (NC) | No internal connection; must remain unconnected per TI specification to avoid parasitic coupling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339N | Rated for 0°C to 70°C only; higher input offset voltage (5 mV typ) and lower supply voltage max (30 V same) | Limited to commercial-temperature consumer or office equipment; unsuitable for automotive or extended industrial use | Select LM339N only for cost-sensitive, non-automotive designs where ambient temperature stays below 70°C |

FAQ
What is the maximum supply voltage for LM2901N/SL65262?
The absolute maximum supply voltage for LM2901N/SL65262 is 36 V, but the recommended operating maximum is 30 V for non-V-suffix devices. This limit ensures reliable operation within specified electrical characteristics and thermal limits across the full –40°C to 125°C temperature range. Exceeding 30 V may degrade long-term stability or increase output saturation voltage beyond datasheet guarantees. LM2901N/SL65262 must be operated within this bound for compliance with its qualified automotive and industrial specifications.
Does LM2901N/SL65262 support dual-supply operation?
Yes, LM2901N/SL65262 supports dual-supply operation with ±1 V to ±15 V range, provided the total supply difference remains between 2 V and 36 V and VCC is at least 1.5 V more positive than the input common-mode voltage. In dual-supply mode, the GND pin serves as the reference midpoint. This flexibility allows LM2901N/SL65262 to interface with bipolar signal sources while retaining its open-collector output architecture and ground-sensing capability on the negative rail.
Can LM2901N/SL65262 inputs go below ground?
No - LM2901N/SL65262 inputs must not go more than 0.3 V below ground, as specified in Absolute Maximum Ratings. The common-mode input range is defined from 0 V to VCC – 1.5 V. Violating the –0.3 V lower limit risks phase reversal, latch-up, or permanent damage. For true below-ground sensing, external level-shifting circuitry or a comparator with extended common-mode range (e.g., TLV3701) is required. LM2901N/SL65262 is designed for ground-referenced or positive-only signal monitoring.
What is the output configuration of LM2901N/SL65262?
LM2901N/SL65262 features four independent open-collector NPN outputs. Each output sinks current when its corresponding comparator asserts (IN+ > IN− + VIO) and presents high impedance otherwise. An external pull-up resistor is mandatory to establish a logic-high state. This architecture enables wired-AND logic, mixed-voltage interfacing, and programmable sink current up to 20 mA per output - a core feature leveraged in fault-bus signaling and multi-threshold alarm systems using LM2901N/SL65262.
Is LM2901N/SL65262 RoHS compliant and lead-free?
Yes, LM2901N/SL65262 is RoHS compliant and lead-free per TI's official packaging documentation. The PDIP package uses matte tin lead finish and meets JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for through-hole assembly. TI confirms full compliance with Directive 2011/65/EU and subsequent amendments, including exemption 7a for lead in high-melting-temperature solder alloys. LM2901N/SL65262 is suitable for environmentally regulated industrial and automotive end equipment without restriction.
