General Description
The IXDN404/IXDI404/IXDF404 is comprised of two 4 Ampere CMOS high speed MOSFET drivers. Each output can source and sink 4A of peak current while producing voltage rise and fall times of less than 15ns to drive the latest IXYS MOSFETs & IGBT's. The input of the driver is compatible with TTL or CMOS and is fully immune to latch up over the entire operating range. A patent-pending circuit virtually eliminates CMOS power supply cross conduction and current shoot-through. Improved speed and drive capabilities are further enhanced by very low, matched rise and fall times. The IXDN404 is configured as a dual non-inverting gate driver, the IXDI404 is a dual inverting gate driver, and the IXDF404 is a dual inverting + non-inverting gate driver. The IXDN404/IXDI404/IXDF404 family are available in the standard 8 pin P-DIP (PI), SOP-8 (SI) and SOP-16 (SI-16) packages.
