The DEIC420 can sourceand sink 20A of peak current while producing voltage riseand fall times of less than 4ns, and minimum pulsewidths of 8ns. The input of the driver is compatible withTTL or CMOS and is fully immune to latch up over theentire operating range. Designed with small internaldelays, cross conduction/current shoot-through isvirtually eliminated in the DEIC420. Its features and widesafety margin in operating voltage and power make theDEIC420 unmatched in performance and value.The DEIC420 is packaged in DEI's low inductance RFpackage incorporating DEI's patented (1) RF layouttechniques to minimize stray lead inductances foroptimum switching performance. For applications that donot require the power dissipation...
