TD3043
Zero-Volt Switching
Triac Driver
DESCRIPTION
The TD3043 consists of a single input LED optically coupled to a zero-volt crossing triac driver. The TD3043 provides high input-to-output
isolation and is designed to drive high-powered triacs. Typical uses include interfacing logic level control signals to equipment powered
from 110Vac and 220Vac lines.
