TheL9700isa monolithiccircuitwhichis suited for
input protectionand voltageclampingpurpose.
The limiting function is referred to ground and the
positivesupplyvoltage.
Onesingleelementcontainssix independentchannels.
Very fast speed is achieved by internal feedback
and the applicationofa new vertical PNP-transistor
with isolatedcollector.
