Integrated Circuit

4–Stage Darlington Array

w/Pre–Drive Stage for TTL

Description:

The NTE2087 is a High–Voltage, High–Current Darlington Array designed to interface low–level logic

to a variety of peripheral loads such as relays, solenoids, d–c 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 VCE(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–speed TTL, and 5V MOS logic.

This device incorporates predriver stages and is most suitable for applications requiring high gain (low

input current loading).

Features:

D TTL, DTL, PMOS, CMOS Compatible Inputs

D Transient Protected Outputs

D Handle Loads to 480 Watts

D Plastic Dual In–Line Package with Heat Sink Contact Tabs

Absolute Maximum Ratings: (TA = +25°C for any one driver unless otherwise specified)
