DM135 - Silicon Touch Technology

DM135 (DM134 - DM136) 16-Bit Constant Current LED Drivers

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. Features 5V CMOS Compatible Input Maximum Clock Frequency: 25MHz (Casc.
