# Industrial Specification: Digital Interface Logic

## 1. Technical Definition
Electronic circuitry that manages digital communication protocols between analog-to-digital/digital-to-analog converters and host systems

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **3.3-5.0 VDC at 25°C ambient, 0-85°C operating temperature, 0-100% relative humidity non-condensing**. Failure boundary: **Voltage exceeding 5.5 VDC causes dielectric breakdown in CMOS gates; sustained operation above 85°C accelerates electromigration in aluminum interconnects beyond 10^6 A/cm² current density**, Mechanism: **Electromigration-induced void formation in metal interconnects at current densities exceeding Black's equation threshold: MTF = A(J-J_crit)^(-n)exp(E_a/kT), where E_a=0.7 eV for aluminum, J_crit=10^6 A/cm² at 100°C**.
