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 and 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), SOIC-8 (SIA) and SOIC-16 (SIA-16) packages. For enhanced thermal performance, the SOP-8 and SOP-16 are also available in a package with an exposed grounded metal back as the SI and SI-16 repectively.

Note 1: Operating the device beyond parameters with listed “Absolute Maximum Ratings” may cause permanent damage to the device. Typical values indicate conditions for which the device is intended to be functional, but do not guarantee specific performance limits. The guaranteed specifications apply only for the test conditions listed. Exposure to absolute maximum rated conditions for extended periods may affect device reliability.
