Product details
Overview
LMC6762BIMX from Texas Instruments is a dual micropower rail-to-rail input CMOS comparator with push-pull output, designed for ultra-low-power sensing and threshold detection in battery-operated systems. It delivers 420 ns propagation delay at 100 mV overdrive (VS = 5 V), 10 μA max supply current per channel, and rail-to-rail input common-mode range exceeding both supplies - enabling direct interface with sensors and 3V digital logic.
For engineers reviewing the LMC6762BIMX datasheet, LMC6762BIMX pinout, LMC6762BIMX application, or LMC6762BIMX equivalent, this page provides verified electrical specifications, SOIC-8 package layout, real-world timing behavior across 2.7–15 V operation, and validated alternatives for portable electronics, metering, and low-voltage monitoring designs.
Technical Context
The LMC6762BIMX implements two independent high-impedance CMOS comparators with rail-to-rail input stages capable of accepting signals beyond V− and V+, and push-pull outputs eliminating external pull-up resistors. Its input offset voltage is specified up to 15 mV (max) at 25°C, with 2.0 μV/°C drift and 75 dB CMRR - ensuring stable threshold detection under varying supply and temperature conditions.
It operates across 2.7 V to 15 V single-supply, with guaranteed functionality at 2.7 V for compatibility with 3V systems. Propagation delay varies from 420 ns (100 mV overdrive, VS = 5 V) to 900 ns (10 mV overdrive), and short-circuit protection limits output current to ±30 mA - supporting robust interfacing to logic gates and microcontroller inputs without external buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 15 V single supply - supports direct integration into 3V, 5V, and 12V battery-powered systems without level-shifting. |
| Max Supply Current | 10 μA per channel - enables multi-year operation on coin-cell batteries in handheld and remote sensor applications. |
| Input Common-Mode Range | Exceeds both rails (e.g., −0.2 V to 5.2 V at VS = 5 V) - allows direct sensing of ground-referenced or rail-referenced signals without bias networks. |
| Propagation Delay | 420 ns @ 100 mV overdrive, VS = 5 V - sufficient for RC timers, zero-crossing detection, and multivibrator circuits below 1 MHz. |
| Output Type | Push-pull (no pull-up required) - drives TTL/CMOS loads directly and reduces BOM count in portable electronics. |
| Input Offset Voltage | 15 mV max (LMC6762BI grade) - sets minimum detectable differential signal in precision window comparators and alarm thresholds. |
| ESD Tolerance | 2 kV HBM - requires standard ESD handling but no additional protection circuitry in typical PCB environments. |
Pinout & Package
LMC6762BIMX is housed in an 8-pin SOIC (D0008A) package with 1.27 mm pitch, 3.91 mm width, and 1.75 mm max height - compatible with standard surface-mount assembly and IPC-7351 land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Comparator A) | High-impedance CMOS input accepting voltages beyond V− and V+ - used for reference or feedback in hysteresis circuits. |
| 2 | Non-Inverting Input (Comparator A) | Same rail-to-rail input capability as Pin 1 - connects to sensor output or signal source in threshold-detection configurations. |
| 3 | Output (Comparator A) | Push-pull CMOS output driving logic-level loads directly - sinks or sources up to 30 mA with <100 mV saturation. |
| 4 | V− (Ground/Ref) | Negative supply terminal - tied to system ground in single-supply operation; supports split-supply use down to −15 V. |
| 5 | Non-Inverting Input (Comparator B) | Independent input for second comparator - enables dual-threshold or window-comparator topologies without external components. |
| 6 | Inverting Input (Comparator B) | Matches Pin 1 performance - used for reference voltage or inverted signal path in differential or latched comparator designs. |
| 7 | Output (Comparator B) | Functionally identical to Pin 3 - allows simultaneous monitoring of two independent analog conditions (e.g., over/under-voltage). |
| 8 | V+ | Positive supply terminal - accepts 2.7–15 V; quiescent current remains stable across full range, simplifying power design. |

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 | Open-drain output (vs. push-pull); otherwise identical specs - same 10 μA IS, 2.7–15 V range, rail-to-rail input. | Requires external pull-up for logic-level output; better suited for wired-OR bus configurations or level translation. | Select LMC6772BIMX only when open-drain functionality is needed - otherwise LMC6762BIMX reduces component count. |
| TLV3702IDR | Lower input offset (1.5 mV max), faster propagation (350 ns), but higher supply current (17 μA) and narrower supply range (2.7–16 V). | Better precision and speed for high-accuracy voltage monitoring; less suitable for ultra-long-life battery applications. | Choose TLV3702IDR when offset and delay are critical - accept 70% higher current draw versus LMC6762BIMX. |
Compared with LMC6762BIMX, LMC6772BIMX trades push-pull simplicity for wired-OR flexibility, while TLV3702IDR improves precision and speed at the cost of micropower efficiency - making LMC6762BIMX optimal for cost-sensitive, long-duration portable electronics where minimal BOM and lowest current dominate.

FAQ
What is the maximum supply voltage rating for the LMC6762BIMX?
The LMC6762BIMX has an absolute maximum supply voltage (V+ − V−) of 16 V, with recommended operating range from 2.7 V to 15 V. Operation above 15 V risks parametric degradation or permanent damage, especially during output short-circuit events. The device is fully characterized and ensured across the 2.7–15 V range, including propagation delay, input offset, and rail-to-rail output swing.
Does the LMC6762BIMX require external pull-up resistors on its outputs?
No, the LMC6762BIMX features push-pull CMOS outputs that actively drive both high and low states - eliminating the need for external pull-up resistors. Each output can source or sink up to 30 mA while maintaining rail-to-rail swing within 100 mV of V+ or V−, making it ideal for direct interfacing with TTL, CMOS, or microcontroller GPIOs in portable electronics.
What is the guaranteed input common-mode voltage range for LMC6762BIMX at 3.3 V supply?
At VS = 3.3 V, the LMC6762BIMX guarantees an input common-mode voltage range from −0.2 V to 3.5 V (exceeding both rails by 200 mV), per the LMC6762BI grade specifications. This allows direct connection to signals referenced to ground or near V+, such as thermistor dividers or op-amp outputs, without level-shifting or biasing networks.
How does the LMC6762BIMX compare to the LMC6762AIMX in terms of precision?
The LMC6762BIMX has a maximum input offset voltage of 15 mV (vs. 8 mV for LMC6762AIMX) and identical 2.0 μV/°C drift. Both share the same rail-to-rail input, push-pull output, and 10 μA supply current. The "B" grade targets cost-sensitive, non-precision applications like basic voltage monitoring or RC timing, whereas the "A" grade suits tighter threshold accuracy needs.
Can the LMC6762BIMX be used in split-supply configurations?
Yes, the LMC6762BIMX supports split-supply operation with V+ and V− pins accepting any differential voltage from 2.7 V to 15 V - e.g., ±5 V or +12 V/−3 V. Input common-mode range extends 200 mV beyond each rail, and output swing remains rail-to-rail relative to the applied supplies. Absolute maximum ratings (e.g., 16 V total) still apply regardless of configuration.
