Overview

Display Drivers DM7856/DM8856.
DM8857.
DM7858/DM8858 BCD-to-7-segment LED drivers general description This series of 7-segment display drivers fulfills a wide variety of requirements for most active high (common cathode) Light Emitting Diodes (LEDs).
Each device fully decodes a 4-bit BCD input into a number from 0 through 9 in the standard 7segment display format, and BCD numbers above 9 into unique patterns that verify operation.
All circuits operate off of a single 5.
0V supply.
The DM7856/DM8856 has active-high, passive pull-up outputs which provide a typical source current of 6.
0 mA at an output voltage of 1.
7V.
The applications are the same as for the DM5448/ DM7448 except that more de...
