Description
The DG5143 solid state analog switch is built on the
Siliconix proprietary high-voltage silicon gate process to
achieve high voltage rating and superior switch time on/off
performance. Break-before-make switching action
guarantees that an on-channel will be turned off before the
off-channel can turn on. The DG5143 features ultra-low
power supply requirements and TTL and CMOS
compatibility.
Each switch conducts equally well in both directions when
on and blocks input voltages to the supply values when off.
This switch is ideal for battery powered industrial
applications with a maximum power supply current of 1
mA.
An expitaxial layer prevents latchup.
