DG444B_11 Datasheet, PDF (1/15 Pages) Vishay Siliconix – Improved Quad SPST CMOS Analog Switches

DG444B, DG445B
Vishay Siliconix
Improved Quad SPST CMOS Analog Switches
DESCRIPTION
The DG444B, DG445B are monolithic quad analog switches
designed to provide high speed, low error switching of analog
and audio signals. The DG444B, DG445B are upgrades to
the original DG444, DG445.
Combing low on-resistance (45 , typ.) with high speed
(t_ON 120 ns, typ.), the DG444B, DG445B are ideally suited
for Data Acquisition, Communication Systems, Automatic
Test Equipment, or Medical Instrumentation. Charge
injection has been minimized on the drain for use in
sample-and-hold circuits.
The DG444B, DG445B are built using Vishay Siliconix’s
high-voltage silicon-gate process. An epitaxial layer prevents
latchup.
When on, each switch conducts equally well in both
directions and blocks input voltages to the supply levels
when off.
