Radiation Hardened 8-Channel Source Driver
IS-2981RH, IS-2981EH
Features
• Electrically screened to SMD # 5962-00520
The Star*Power 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
• QML qualified per MIL-PRF-38535 requirements

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.
