DG642DY-E3產(chǎn)品概述
The DG641/642/643 are high performance monolithic video switches designed for switching wide bandwidth analog and digital signals. DG641 is a quad SPST, DG642 is a single SPDT, and DG643 is a dual SPDT function. These devices have exceptionally low on-resistances (5 Ω typ—DG642), low capacitance and high current handling capability. To achieve TTL compatibility, low channel capacitances and fast switching times, the DG641/642/643 are built on the Vishay Siliconix proprietary D/CMOS process. Each switch conducts equally well in both directions when on, and blocks up to 14 Vp-p when off. An epitaxial layer prevents latchup.
