Microchip HT0740LG-G, MOSFET 1, 5.5V 8-Pin, SOIC

The HT0740 is a single-channel high-voltage low input
current isolated driver that uses the 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 +VOUT and –VOUT when the logic input
is at a logic high. The HT0740 does not require any
external power supplies. The internal supply voltage is
provided by the logic input when it is in high state.

Features:
±400V Input to Output Isolation
Low Input Logic Current, 500 μA (Maximum)
No External Voltage Supply Required
Floating Isolated Output Drivers
5V Logic Compatible
Applications:
Telecommunications
Modems
Solid State Relays
High-side Switches
High-end Audio Switches
Avionics
Automatic Test Equipment
