DG441, DG442
Vishay Siliconix
Quad SPST CMOS Analog Switches
FEATURES
DESCRIPTION
•
Halogen-free according to IEC 61249-2-21
Definition
The DG441, DG442 monolithic quad analog switches are
designed to provide high speed, low error switching of analog
and audio signals. The DG441 has a normally closed
function. The DG442 has a normally open function.
Combining low on-resistance (50 , typ.) with high speed
(tON 150 ns, typ.), the DG441, DG442 are ideally suited for
upgrading DG201A/202 sockets. Charge injection has been
minimized on the drain for use in sample-and-hold circuits.

Low on-resistance: 50
Low leakage: 80 pA
Low power consumption: 0.2 mW
Fast switching action - tON: 150 ns
Low charge injection - Q: - 1 pC
DG201A/DG202 upgrades
TTL/CMOS-compatible logic
Single supply capability
Compliant to RoHS Directive 2002/95/EC
To achieve high voltage ratings and superior switching
performance, the DG441, DG442 are built on Vishay
Siliconix’s high-voltage silicon-gate process. An epitaxial
layer prevents latchup.
BENEFITS
•
•
•
•
•
•
•
Less signal errors and distortion
Reduced power supply requirements
Faster throughput
Improved reliability
Reduced pedestal errors
Simplifies retrofit
Each switch conducts equally well in both directions when
on, and blocks input voltages to the supply levels when off.
Simple interfacing
