NTE2087 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).
