# Industrial Specification: Comparator

## 1. Technical Definition
An electronic circuit or device that compares two input signals and outputs a digital signal indicating which is larger.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **Input voltage differential: 0-5 mV for precision comparators, 0-100 mV for general-purpose comparators; Response time: 10 ns to 1 μs depending on technology; Temperature range: -40°C to +125°C for industrial-grade components**. Failure boundary: **Input offset voltage exceeding 10 mV causes erroneous output states; Common-mode input voltage exceeding supply voltage by 0.3 V causes latch-up; Slew rate dropping below 1 V/μs creates timing errors in digital systems**, Mechanism: **Electromigration in aluminum interconnects at current densities above 10^6 A/cm²; Dielectric breakdown in silicon dioxide layers at electric fields exceeding 10 MV/cm; Thermal runaway in output transistors when junction temperature exceeds 150°C**.
