NTE 8-Channel Darlington Array/Driver ULN2803 Equivalent
Under the proper conditions, high−power loads up to 4A at 50V (200W at 23% duty cycle) or 3.2A at 95V (304W at 33% duty cycle) can be controlled. All devices feature open collector outputs and integral diodes for inductive load transient suppression. The NTE2018 has a 2.7k series base resistor for each Darlington pair, allowing operation directly with TTL or CMOS operating at a supply voltage of 5V. This device will handle numerous interface needs − particularly those beyond the capabilities of standard logic buffers.
