NTE7226
Integrated Circuit
High Voltage, High Speed MOSFET/IGBT Driver
w/High and Low Side Outputs
14−Lead DIP Type Package
Description:
The NTE7226 is a high voltage, high speed power MOSFET and IGBT driver with independent high
and low side referenced output channels in a 14−Lead DIP type package. HVIC and latch immune
CMOS technologies enable ruggedized monolithic construction. Logic inputs are compatible with
standard CMOS or LSTTL output, down to 3.3V logic. The output drivers feature a high pulse current
buffer stage designed for minimum driver cross−conduction. Propagation delays are matched to sim-
plify use in high frequency applications. The floating channel can be used to drive an N−Channel
power MOSFET or IGBT in the high side configuration which operates up to 500 volts.

Note 1. Absolute Maximum Ratings indicate sustained limits beyond which damage to the device
may occur. All voltage parameters are absolute voltages referenced to COM. The thermal
resistance and power dissipation ratings are measured under board mounted and still air
conditions.
