LED Driver IC
IK2107
DESCRIPTION
The IK2107 is specifically designed for cathode-grid LED and
LED DISPLAY derivers.
The IK2107 have 12/9 segment output lines, 7 to 4 grid output lines, one
display memory, control circuit and 3 line serial data interface. This
function are all incorporated into a single chip to build a highly reliable
peripheral device for a single chip microcomputer. It is very convenience
to control for numeric display.
IK2107’s pin assignments and application circuit are optimized for easy
PCB Layout and cost saving advantages.
