IT1401
16-bit Constant Current LED Sink Driver
General Description
IT1401 is a 16-bit constant current LED
driver incorporating shift register and data
latch designed for LEDs and LED displays.
The output current can be set using an
external resistor.
All outputs have virtually the same current
levels. Sixteen regulated current ports are
designed to provide uniform and constant
current for driving LEDs within a large range
of V
F
variations.
