DESCRIPTION

The STG719 is an high-speed S.P.D.T. (Single
Pole Double Throw) SWITCH fabricated in silicon
gate C

2

MOS technology. It designed to operate
from 1.8V to 5.5V, making this device ideal for
portable applications, audio signal ro uting, video
switching, mobile and communicat ion system s.
It offers 4Ω ON-Resistance Max at 5V 25°C and
very low ON-Resistance Flatness. Addition al key
features are fast switching speed (t

Low Power Consumption.
All inputs and outputs are equipped with
protection circuits against static disc harge, giving
them ESD immunity and transient excess voltage.
It’s available in the commercial and extended
temperature range.
