16-Bit Constant Current LED Drivers

General Description

The DM134、DM135、DM136 are constant current drivers specifically designed for LED

display applications. The value of constant current can be varied using an external resistor. The

devices include a 16-bit shift register, latches, and constant current drivers on a single Silicon

CMOS chip.
