CD40109BD

Translators, Level Shifters Overview

The CD40109BD is a unidirectional voltage level translator manufactured by Harris Corporation. It features four independent circuits within a single 16-CDIP package. The device facilitates signal translation between different voltage domains without requiring the presence of the high-voltage supply (VDD). It operates as a single-channel translator designed for low-to-high level shifting applications in CMOS logic systems.
