NTE2088
Integrated Circuit
4Segment Darlington Array,
w
/PreDriver Stage
for use with PMOS and 12V CMOS
Description:
The NTE2088 is a High voltage, high current Darlington array in a 16Lead DIP type package designed
as an interface between lowlevel logic and a variety of peripheral loads such as relays, solenoids, DC
and stepper motors, multiplexed LED and incandescent displays, heaters, and similar loads to 480
Watts (1.5A per output, 80V, 26% duty cycle).
This device has a minimum output breakdown of 50V and a minimum V
CE(sus)
of 35V measured at
100mA, or a minimum output breakdown of 80V and a minimum V
CE(sus)
of 50V.
A copperalloy lead frame provides maximum power dissipation using standard cooling methods.
This lead configuration facilitates attachment of external heat sinks for increased power dissipation
with standard IC sockets and printed wiring boards.
