Overview
The MC14042BDR2G is a Quad Transparent Latch produced by onsemi. This device is constructed with MOS P-channel and N-channel enhancement mode devices in a single monolithic structure. It features four latches, each with a separate data input, but all sharing a common clock. The clock polarity can be controlled, allowing data transfer during either the high or low clock level based on the polarity input state. This component is part of the MC14042B series and is packaged in a SOIC-16 (Pb-Free) format, making it suitable for various electronic applications requiring reliable and versatile latching functionality.
