General Description
The IXDD404 is comprised of two 4 Amp CMOS high speed
MOSFET drivers. Each output can source and sink 4 A 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. Designed
with small internal delays, cross conduction/current shoot-
through is virtually eliminated in the IXDD404. Improved speed
and drive capabilities are further enhanced by very low,
matched rise and fall times.
Additionally, each driver in the IXDD404 incorporates a unique
ability to disable the output under fault conditions. When a
logical low is forced into the Enable input of a driver, both of it's
final output stage MOSFETs (NMOS and PMOS) are turned
off. As a result, the respective output of the IXDD404 enters a
tristate mode and achieves a Soft Turn-Off of the MOSFET/
IGBT when a short circuit is detected. This helps prevent
damage that could occur to the MOSFET/IGBT if it were to be
switched off abruptly due to a dv/dt over-voltage transient.
The IXDD404 is 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 avail-
able with an exposed grounded metal back package as the SI
and SI-16 respectively.

DESCRIPTION
The Channel A enable pin. This pin, when driven low, disables the A
Channel, forcing a high impedance state to the A Channel Output.
A Channel Input signal-TTL or CMOS compatible.
The system ground pin. Internally connected to all circuitry, this pin provides
ground reference for the entire chip. This pin should be connected to a low
noise analog ground plane for optimum performance.
B Channel Input signal-TTL or CMOS compatible.
B Channel Driver output. For application purposes, this pin is connected,
through a resistor, to Gate of a MOSFET/IGBT.
Positive power-supply voltage input. This pin provides power to the entire
chip. The range for this voltage is from 4.5V to 35V.
A Channel Driver output. For application purposes, this pin is connected,
through a resistor, to Gate of a MOSFET/IGBT.
The Channel B enable pin. This pin, when driven low, disables the B
Channel, forcing a high impedance state to the B Channel Output.
CAUTION: These devices are sensitive to electrostatic discharge; follow proper ESD procedures when
handling and assembling this component.
