DM135B (DM134B / DM135B) 16 BIT CONSTANT CURRENT LED DRIVERS

The DM134B、DM135B 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 3.3V~5V CMOS Compatible Input Maximum Clock Frequency: 25MHz (Cas.
