Product details
Overview
LMC6762BIM/NOPB from Texas Instruments is a dual micropower rail-to-rail input CMOS comparator with push-pull output, designed for ultra-low-power battery-operated systems. It delivers 10 μA max supply current per comparator, operates from 2.7V to 15V, and achieves rail-to-rail input common-mode range exceeding both supplies - enabling direct sensing near ground or V+ in 3V digital systems.
For engineers reviewing the LMC6762BIM/NOPB datasheet, LMC6762BIM/NOPB pinout, LMC6762BIM/NOPB application, or LMC6762BIM/NOPB equivalent, key selection criteria include guaranteed 2.7V operation, 420ns propagation delay at 100mV overdrive (5V supply), push-pull output eliminating external pull-ups, ±0.02pA input bias current, and SOIC-8 packaging compatible with space-constrained portable designs.
Technical Context
The LMC6762BIM/NOPB implements a CMOS input stage with 20fA typical input current and 75dB CMRR, enabling high-impedance sensor interfacing without bias networks. Its rail-to-rail input extends 200mV beyond V− and V+ at 2.7V, 5V, and 15V supplies - critical for low-voltage power monitoring and zero-crossing detection.
The push-pull output drives logic directly with VOH ≥ 4.6V and VOL ≤ 0.4V at 5V/5mA, while short-circuit protection limits sink/source current to 30mA/45mA. Propagation delay remains stable across temperature (−40°C to +85°C) and supply voltage, with tPLH = 420ns and tPHL = 450ns specified at 2.7V/100mV overdrive.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 10 μA max per comparator - enables multi-year battery life in handheld meters and IoT sensors |
| Supply Voltage Range | 2.7V to 15V - supports single-cell Li-ion, 3V logic, and industrial 12V rails without level-shifting |
| Input Common-Mode Range | Exceeds V− by 0.2V and V+ by 0.2V at 2.7V - allows direct interface to signals below ground or above V+ |
| Propagation Delay | 420ns (tPLH) @ 100mV overdrive, 5V - sufficient for RC timers, window comparators, and multivibrators up to ~1MHz |
| Output Type | Push-pull - eliminates need for external pull-up resistors when driving TTL/CMOS logic or microcontroller GPIO |
| Input Offset Voltage | 15 mV max (LMC6762BI grade) - suitable for coarse threshold detection in alarm circuits and battery monitors |

| 3 | Output (Comparator A) | Push-pull CMOS output; sinks/sourced up to 30mA/45mA; no external pull-up required |
| 4 | V− (Ground/Ref) | Power return for single-supply (0V) or negative rail in split-supply configurations |
| 5 | Non-Inverting Input (Comparator B) | Independent input for second channel; identical rail-to-rail performance as Pin 2 |
| 6 | Inverting Input (Comparator B) | Independent input for second channel; matches Pin 1 electrical behavior |
| 7 | Output (Comparator B) | Dedicated push-pull output; electrically isolated from Output A; drives separate logic loads |
| 8 | V+ | Positive supply rail; accepts 2.7V–15V; quiescent current independent of V+ value |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMC6772BIM/NOPB | Open-drain output instead of push-pull; otherwise identical specs including 10μA IS, 2.7–15V range, and rail-to-rail input | Requires external pull-up for logic-level output; better suited for wired-OR bus configurations or level translation | Select LMC6772BIM/NOPB only when open-drain functionality is explicitly needed; LMC6762BIM/NOPB preferred for simplified logic interfacing |
| TLV3702IDR | Lower input offset voltage (3mV max), higher supply current (1.8μA typ per channel), same SOIC-8 package and 2.7–16V range | Better precision for tight-threshold applications; less suitable for ultra-low-power >10-year battery life | Choose TLV3702IDR when offset voltage <5mV is mandatory; retain LMC6762BIM/NOPB for micropower priority |
Compared with LMC6772BIM/NOPB, LMC6762BIM/NOPB eliminates pull-up components and reduces board area; versus TLV3702IDR, it trades 12× lower supply current for relaxed offset tolerance - making it optimal for cost-sensitive, long-life portable instrumentation.

FAQ
What is the maximum supply voltage rating for LMC6762BIM/NOPB?
The absolute maximum supply voltage (V+ – V−) for LMC6762BIM/NOPB is 16V, with recommended operating range from 2.7V to 15V. Exceeding 16V risks permanent damage; operation at 15V is fully characterized in the datasheet with VOH ≥14.45V and VOL ≤0.55V at 5mA load.
Does LMC6762BIM/NOPB support true rail-to-rail input beyond the supply rails?
Yes - LMC6762BIM/NOPB guarantees input common-mode voltage range extending 200mV beyond both V− and V+ at 2.7V, 5V, and 15V supplies. At 2.7V, this means −0.2V to +2.9V, enabling direct interface to signals that dip below ground or exceed V+ without clamping diodes.
Can LMC6762BIM/NOPB drive standard CMOS or TTL logic directly?
Yes - its push-pull output drives CMOS and TTL logic directly without external pull-up resistors. At 5V supply and 5mA load, VOH ≥4.45V and VOL ≤0.55V meet 74HC and LVTTL input thresholds; at 2.7V, VOH ≥2.3V and VOL ≤0.4V satisfy 1.8V/2.5V logic families.
What is the guaranteed propagation delay for LMC6762BIM/NOPB at 2.7V operation?
At V+ = 2.7V, 100mV input overdrive, and 25°C, LMC6762BIM/NOPB guarantees tPLH ≤ 420ns and tPHL ≤ 450ns. These values are tested and ensured across the full −40°C to +85°C junction temperature range per the LMC6762BI grade specification.
Is LMC6762BIM/NOPB pin-compatible with other members of the LMC6762 family?
Yes - all LMC6762 variants (AIM, BIM, AIMX/NOPB, BIMX/NOPB) share identical SOIC-8 pinout and electrical behavior. The 'B' suffix denotes the LMC6762BI grade (15mV max VOS), while 'A' indicates LMC6762AI (8mV max VOS); both use the same footprint and connectivity.
