NTE1509 Datasheet (NTE) - Integrated Circuit 10-Step Dot/Bar Display Driver

NTE1509, Integrated Circuit 10-Step Dot/Bar Display Driver

The NTE1509 is a monolithic integrated circuit in an 18 *Lead DIP type package that senses analog voltage levels and drives 10 LEDs, LCDs, or vacuum fluorescent displays, providing a logarithmic 3dB analog display.

A single pin changes the display from a bar graph to a moving dot display.
