Radiation Hardened Dual, Non-Inverting Power MOSFET
Drivers
HS-4424RH, HS-4424EH,
HS-4424BRH, HS-4424BEH
Features
• Electrically screened to DESC SMD # 5962-99560
• QML qualified per MIL-PRF-38535 requirements
• EH version acceptance tested to 50krad(Si) (LDR)
The Radiation Hardened HS-4424RH, HS-4424EH,
HS-4424BRH and HS-4424BEH are non-inverting, dual,
monolithic high-speed MOSFET drivers designed to convert TTL
level signals into high current outputs at voltages up to 18V.
• Radiation environment

- Latch-up immune
The inputs of these devices are TTL compatible and can be
directly driven by our HS-1825ARH PWM device or by our
ACS/ACTS and HCS/HCTS type logic devices. The fast rise
times and high current outputs allow very quick control of high
gate capacitance power MOSFETs in high frequency
applications.

• Low voltage lock-out feature
The high current outputs minimize power losses in MOSFETs by
rapidly charging and discharging the gate capacitance. The
output stage incorporates a low voltage lock-out circuit that
puts the outputs into a three-state mode when the supply
voltage drops below 10V for the HS-4424RH, HS-4424EH and
7.5V for the HS-4424BRH, HS-4424BEH.

Constructed with the Intersil dielectrically isolated Rad Hard
Silicon Gate (RSG) BiCMOS process, these devices are immune
to Single Event Latch-up and have been specifically designed
to provide highly reliable performance in harsh radiation
environments.
