General Description
The Supertex HT0740 is a single channel high voltage, low input
current isolated driver utilizing Supertex’s proprietary HVCMOS^®
technology. It is designed to drive discrete MOSFETs configured
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.
Applications
❏ Telecommunications
❏ Modems
❏ Solid state relays
❏ High side switches
❏ High end audio switches
❏ Avionics
❏ ATE
