General Description

The Supertex HT0740 is a single channel, high voltage, low

input current, isolated driver utilizing Supertex’s proprietary

HVCMOS

MOSFETs, conﬁ gured as high side switches, up to 400V.

The HT0740 generates an independent DC isolated voltage

across the pair of outputs when the logic input is at a logic

high. The HT0740 does not require any external power

supplies. The internal supply voltage is supplied from the

logic input when it is in the high state.
