DESCRIPTION
The DG2731/2732/2733 are low voltage, low on-resistance,
dual single-pole/double-throw (SPDT) monolithic
CMOS analog switches designed for high
performance switching of analog signals. Combining
low-power, high speed, low on-resistance, and small
package size, the DG2731/2732/2733 are ideal for
portable and battery power applications.
The DG2731/2732/2733 have an operation range from
1.6 V to 4.3 V single supply. The DG2731 and DG2732
have two separate control pins with reverse control
logic. The DG2733 has an EN pin to enable the device
when the logic is high.
The DG2731/2732/2733 are 1.6-V logic compatible,
allowing the easy interface with low voltage DSP or
MCU control logic and ideal for one cell Li-ion battery
direct power.
The switch conducts signals within power rails equally
well in both directions when on, and blocks up to the
power supply level when off. Break-before-make is
guaranteed.
The DG2731/2732/2733 are built on Vishay Siliconix's
sub micron CMOS low voltage process technology and
provides greater than 300 mA latch-up protection, as
tested per JESD78.
As a committed partner to the community and the environment,
Vishay Siliconix manufactures this product
with lead (Pb)-free device terminations. DG2731/2732/
2733 are offered in a DFN or MSOP package. The
DFN package has a nickel-palladium-gold device termination
and is represented by the lead (Pb)-free "-E4"
suffix. The MSOP package uses 100% matte Tin
device termination and is represented by the lead (Pb)-
free "-E3" suffix. Both the matte Tin and nickel-palladium-
gold device terminations meet all JEDEC standards
for reflow and MSL ratings.
