Product details
Overview
LMC6762BIMX/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, achieves rail-to-rail input common-mode range exceeding both supplies, and provides rail-to-rail output swing within 100 mV of rails at 2.7V/2.5 mA - enabling direct logic interfacing in portable metering and handheld electronics.
For engineers reviewing the LMC6762BIMX/NOPB datasheet, LMC6762BIMX/NOPB pinout, LMC6762BIMX/NOPB application, or LMC6762BIMX/NOPB equivalent, key selection criteria include guaranteed 2.7V operation, <15 mV input offset voltage (max), 420 ns propagation delay at 100 mV overdrive, push-pull output eliminating external pull-ups, and SOIC-8 packaging compatible with space-constrained PCB layouts.
Technical Context
The LMC6762BIMX/NOPB implements a CMOS input stage with 0.02 pA typical input bias current and 75 dB common-mode rejection, enabling high-impedance sensor interfacing without signal degradation. Its rail-to-rail input extends 200 mV beyond V− and V+, ensuring reliable threshold detection even with signals near supply rails.
Push-pull output architecture delivers sourcing/sinking capability up to ±30 mA with short-circuit protection rated at 40 mA, supporting direct drive of TTL/CMOS loads across 2.7–15 V supply range while maintaining 50 μW quiescent power at 5 V - critical for always-on monitoring circuits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMC6772BIMX/NOPB | Open-drain output instead of push-pull; identical supply current, offset, and speed specs | Requires external pull-up for logic-level output; better suited for wired-OR bus configurations | Select when interfacing with multiple comparators on shared output line or driving NMOS gates |
| TLV3702IDR | Lower 1.8 V min supply; 360 ns propagation delay; 1.25 mV max offset; SOIC-8 package | Higher precision and lower voltage support, but 2× higher supply current (24 μA) | Select when tighter offset (<1.25 mV) and sub-2.7 V operation are mandatory, accepting higher power |
Compared with LMC6762BIMX/NOPB, LMC6772BIMX/NOPB trades push-pull convenience for wired-OR flexibility, while TLV3702IDR offers superior precision and lower-voltage capability at the cost of increased quiescent current - making LMC6762BIMX/NOPB optimal for ultra-low-power, single-supply, logic-direct applications.

FAQ
What is the maximum supply voltage rating for LMC6762BIMX/NOPB?
The absolute maximum supply voltage (V+ − V−) for LMC6762BIMX/NOPB is 16 V, with recommended operating range from 2.7 V to 15 V. Exceeding 16 V risks permanent damage, and continuous short-circuit operation above 12 V on the output may degrade reliability per TI's datasheet Section 5 and 11.3.
Does LMC6762BIMX/NOPB support true rail-to-rail input operation?
Yes, LMC6762BIMX/NOPB supports rail-to-rail input common-mode voltage range extending 0.2 V below V− and 0.3 V above V+ at room temperature, verified across 2.7 V, 5 V, and 15 V supplies per Sections 7–8 and Application Hint 11.1. This enables accurate threshold detection at ground and supply rails without external level shifting.
Can LMC6762BIMX/NOPB drive TTL or CMOS logic directly?
Yes, LMC6762BIMX/NOPB features a push-pull output that sources/sinks up to ±30 mA and swings within 100 mV of V+ and V− at 2.7 V/2.5 mA, meeting TTL high/low voltage thresholds and fully compatible with 3.3 V and 5 V CMOS inputs - eliminating need for external pull-up resistors.
What is the input offset voltage specification for LMC6762BIMX/NOPB?
The input offset voltage for LMC6762BIMX/NOPB is 15 mV maximum over temperature (−40°C to +85°C), with typical value of 3 mV at 25°C. This is explicitly specified in Section 7 (2.7 V Electrical Characteristics) and Section 8 (5.0 V/15.0 V Electrical Characteristics) of the datasheet.
Is LMC6762BIMX/NOPB pin-compatible with LMC6762AIMX/NOPB?
Yes, LMC6762BIMX/NOPB and LMC6762AIMX/NOPB share identical SOIC-8 (D) package, pinout, and electrical interface; the only difference is grade - 'B' grade has 15 mV max VOS vs. 'A' grade's 8 mV max VOS. Both operate across −40°C to +85°C and support identical supply ranges and output drive capabilities.
