8x2-Bit Constant Current LED Drivers

General Description

The DM141 is a constant current driver specifically designed for LED display

applications. The device includes a 16-bit shift register, a latch, and dual-interleaved banks of

constant current drivers on a single Silicon CMOS chip. Each of the dichotomous 8-bit banks

requires a current setting resistor. The output current ranges from 5mA to 60mA.
