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.
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.
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.
Specifications for Rad Hard QML devices are controlled by the Defense Logistics Agency Land and Maritime (DLA). The SMD numbers listed here must be used when ordering.
