HT3914A Overview
The individual outputs can drive a transistor The HT3914A is a monolithic integrated circuit that as well as a LED at the same time, so controller senses analog voltage levels and drives 10 LEDs, functions including “staging” control can be providing a linear analog display. The HT3914A can also act as a changes the display from a moving dot to a bar programmer, or sequencer. Current drive to the LEDs is regulated...
