Low-Voltage, Low R
ON
Quad SPST Analog Switch
DESCRIPTION
The DG2041/2042/2043 are quad single-pole/single-throw
monolithic CMOS analog switch designed for high
performance switching of analog signals. Combining low
power, fast switching, low on-resistance (R
DS(on)
: 1 at
2.7 V) and small physical size, the DG2041/2042/2043 are
ideal for portable and battery powered applications requiring
high performance and efficient use of board space.
The DG2041/2042/2043 are built on Vishay Siliconix’s new
high density low voltage process. An epitaxial layer prevents
latchup.
Each switch conducts equally well in both directions when
on, and blocks up to the power supply level when off.
FEATURES
• Low Voltage Operation (1.8 V to 5.5 V)
• Low On-Resistance - R
