NTE NTE2085

NTE2085 & NTE2086
Integrated Circuit
4–Stage Darlington Array
Description:
The NTE2085 and NTE2086 are high voltage, high current Darlington arrays in a 16–Lead DIP type
package are designed for use as an interface between low–level 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).
The NTE2085 is a quad driver intended for use with TTL, low–speed TTL, and 5V MOS logic. The
NTE2086 is similar to the NTE2085 except that it is designed for use with PMOS and 12V CMOS logic.
Features:
D TTL, DTL, PMOS, and CMOS Compatible Inputs
D Transient–Protected Outputs
D Loads to 480 Watts
D Heat–Sink Contact Tabs
Absolute Maximum Ratings: (TA = +25°C for any one driver unless otherwise specified)
