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 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 V
p-p
when off. An epitaxial layer prevents latchup.
