What is MC145003FU?
This is 128 Segment LCD Drivers. A seven-segment display is an electronic display device used to display decimal numerals, most often as an alternative to the more complex dot-matrix displays. It is composed of seven segments (LEDs or LCDs), each of which can be lit or turned off independently to represent the decimal digits 0 to 9. |
