The ULN2004AN with Darlington transistor array driver DIP-16 RoHS manufactured by HTC Korea is a 16-channel low-voltage high-current Darlington array. It is a high-voltage, high-current integrated circuit designed for interfacing TTL logic circuitry to low-voltage, high-current loads. The ULN2004AN comes in a RoHS compliant, 16-pin DIP package. Its outputs are rated to sink 500mA from a 50V supply, making it ideal for most automotive, industrial and home applications. It features a low signal to load current ratio, 500mA source and sink current rates, and a common emitter for each output. Additionally, the ULN2004AN contains high gain, high gain, low saturation voltage Darlington transistors to ensure low-distortion output and reliable operation up to 6MHz frequency.
