The A6281 is designed to minimize the number of components needed to drive LEDs with large pixel spacing. The remaining bits are used for the data. The maximum current is set by an external resistor. The package is lead (Pb) free with 100% matte-tin leadframe plating.

A large number of A6281s can be daisy chained together and controlled by just four control signals (clock, serial data, latch, and output enable). The A6281 controls LED brightness with a Pulse Width Modulation (PWM) scheme that gives the application the capability of displaying a billion colors in an RGB cluster. All the internal latched registers are loaded a 32-bit shift register. This BiCMOS device includes an On/Off shift register, a Dot Correction A6282 16-Channel Constant-Current LED DriverThe A6282 device is designed for LED display applications.
