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