NTE2087
Integrated Circuit
4鈥揝tage Darlington Array
w
/Pre鈥揇rive Stage for TTL
Description:
The NTE2087 is a High鈥揤oltage, High鈥揅urrent Darlington Array designed to interface low鈥搇evel logic
to a variety of peripheral loads such as relays, solenoids, d鈥揷 and stepper motors, multiplexed LED
and incandescent displays, heaters, and similar loads to 480 watts (1.5 A per output, 80V, 26% duty
cycle).
This device is specified with a minimum output breakdown of 50 volts and V
CE(sus)
minimum of 35
volts measured at 100mA and an output current specification of 1.5A (saturated).
A Quad driver Type, the NTE2087 is intended for use with TTL, low鈥搒peed TTL, and 5V MOS logic.
This device incorporates predriver stages and is most suitable for applications requiring high gain (low
input current loading).
