Product details
Overview
LM360M/NOPB from Texas Instruments is a high-speed differential comparator with complementary TTL outputs, 20 ns maximum propagation delay, ±5 V differential input range, and operation over 0°C to +70°C. It serves as a pin-for-pin replacement for μA760/μA760C in zero-crossing detectors and high-speed analog-to-digital converter front-ends.
For engineers reviewing the LM360M/NOPB datasheet, LM360M/NOPB pinout, LM360M/NOPB application, or LM360M/NOPB equivalent, key selection criteria include propagation delay matching between complementary outputs, input offset voltage ≤5 mV, fan-out of 4, and SOIC-8 compatibility with standard TTL logic interfaces.
Technical Context
The LM360M/NOPB implements a bipolar differential pair architecture optimized for speed and low skew, delivering tightly matched propagation delays (≤2 ns difference between complementary outputs) across its full operating temperature range. Its high input impedance (17 kΩ at 1 MHz) and low input capacitance (3 pF) minimize loading on preceding signal sources.
It operates from dual supplies (±4.5 V to ±6.5 V), supports common-mode input voltages up to ±4.5 V, and delivers TTL-compatible output levels: VOH ≥2.4 V at −320 µA sink and VOL ≤0.4 V at 6.4 mA sink - enabling direct interfacing with 74-series logic without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 13–25 ns typical/max; enables sampling rates >30 MHz in ADC timing paths. |
| Delay Matching | ≤2 ns skew between complementary outputs; critical for balanced latch or flip-flop clocking. | Input Offset Voltage | 2–5 mV max; ensures reliable detection of small differential signals above noise floor. |
| Supply Range | ±4.5 V to ±6.5 V; supports industrial 5 V rail systems with margin for ripple and tolerance. |
| Fan-out | 4 TTL loads; sufficient to drive multiple downstream logic gates without buffering. |
| Operating Temp | 0°C to +70°C; suitable for commercial-grade embedded control and data acquisition systems. |
Pinout & Package
LM360M/NOPB is housed in an 8-pin SOIC (D) package per JEDEC MS-012 variation AA, 3.91 mm body width, 1.75 mm max height, with gull-wing leads and pin 1 marked by notch or bevel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (−IN) | Differential input node; referenced to non-inverting input for threshold comparison. |
| 2 | Non-inverting Input (+IN) | Differential input node; defines polarity of output transition relative to −IN. |
| 3 | Negative Supply (V−) | Ground reference for internal biasing; must be connected to −5 V supply rail. |
| 4 | Output A (Q) | Complementary TTL output; active-high when +IN > −IN by >5 mV overdrive. |
| 5 | Output B (Q̅) | Complementary TTL output; inverted logic state of Output A; enables differential latch interface. |
| 6 | Positive Supply (V+) | Power rail for internal circuitry; must be connected to +5 V supply rail. |
| 7 | Compensation | Internal compensation node; no external connection required per datasheet design. |
| 8 | Ground / Reference | Signal ground reference; ties internal bias network to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Complementary TTL Outputs | Simultaneous Q and Q̅ outputs eliminate need for external inverters in edge-triggered circuits. |
| Tight Delay Matching | ≤2 ns inter-output skew ensures deterministic timing in synchronous sampling and latching. |
| Low Input Offset Drift | 8 µV/°C tempco maintains threshold stability across ambient temperature variations. |
| High Input Impedance | 17 kΩ || 3 pF minimizes loading on precision sensor or DAC output stages. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed differential comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM360MX/NOPB | Same die, tape-and-reel packaging (2500 pcs/reel); identical electrical specs and SOIC-8 footprint. | Optimized for automated SMT assembly; same thermal and timing behavior as LM360M/NOPB. | Select LM360MX/NOPB for high-volume production; LM360M/NOPB for prototyping or low-volume builds. |
| TL3016CD | Higher speed (4.5 ns typ), single-supply (5 V only), no complementary outputs; requires external inverter for Q̅. | Better suited for ultra-high-speed single-ended systems where layout space permits added logic. | Choose TL3016CD only if <10 ns delay is mandatory and complementary outputs can be synthesized externally. |
Compared with LM360MX/NOPB, LM360M/NOPB offers identical performance in tube packaging for manual or semi-automated placement; versus TL3016CD, LM360M/NOPB provides built-in complementary outputs and dual-supply flexibility at the cost of ~15 ns higher delay - making it preferable for robust, TTL-integrated timing designs.

FAQ
What is the maximum propagation delay specification for LM360M/NOPB?
The LM360M/NOPB has a maximum propagation delay of 25 ns under standard test conditions (TA = 25°C, VS = ±5 V, fanout = 1). This value is guaranteed across the full 0°C to +70°C operating range and applies to both complementary outputs, supporting timing-critical designs such as ADC sampling and zero-crossing detection where deterministic latency is essential.
Does LM360M/NOPB require external compensation components?
No, LM360M/NOPB does not require external compensation components. Pin 7 is an internal compensation node with no external connection needed - the device is internally compensated for stable operation across its specified supply and load conditions, simplifying PCB layout and reducing bill-of-materials count in high-speed timing circuits.
Can LM360M/NOPB operate from a single 5 V supply?
No, LM360M/NOPB requires dual supplies: a positive rail (V+) and a negative rail (V−). The absolute maximum ratings specify ±8 V, and recommended operating conditions are ±4.5 V to ±6.5 V. It cannot function correctly on a single 5 V supply because its internal circuitry relies on symmetric bipolar biasing for optimal speed and offset performance.
What is the input common-mode voltage range for LM360M/NOPB?
The input common-mode voltage range for LM360M/NOPB is ±4.5 V when operated at ±6.5 V supplies. This wide range allows the device to accept differential signals centered at ground or shifted within the supply rails - a key advantage in noisy industrial environments where sensor outputs may float significantly relative to system ground.
Is LM360M/NOPB RoHS compliant and lead-free?
Yes, LM360M/NOPB is RoHS compliant and features a matte tin (SN) lead finish. Per TI's packaging addendum, it carries "Yes" for RoHS and "Level-1-260C-UNLIM" for moisture sensitivity rating, confirming full compliance with EU Directive 2011/65/EU and suitability for standard reflow soldering processes without special handling requirements.
