IS-2981RH, IS-2981EH

Radiation Hardened 8-Channel Source Driver

DATASHEET

The Radiation Hardened IS-2981RH, IS-2981EH are monolithic

devices designed for use in high-side switching applications

that benefit from separate grounds for the logic and loads. The

devices have a 5V to 80V operating supply voltage range and is

capable of sourcing -200mA continuously from each output.

The outputs are controlled by active-high inputs and may be

paralleled to increase the drive current. The output clamp

diodes prevent device damage, when switching inductive

loads.

Constructed with the Intersil bonded wafer, dielectrically

isolated HVTDLM process, these single event latch-up immune

devices have been specifically designed to provide highly

reliable performance in harsh radiation environments. They

are fully guaranteed for 100krad(Si) high dose rate and

50krad(Si) low dose rate total dose performance through

wafer-by-wafer radiation testing, and are production tested

over the full military temperature range.

Specifications for Rad Hard QML devices are controlled by the

Defense Logistics Agency Land and Maritime (DLA). The SMD

numbers listed below must be used when ordering.

Detailed Electrical Specifications for these devices are

contained in SMD 5962-00520. A “hot-link” is provided on our

homepage for downloading
