📥 Download Datasheet

General Description

The TLC59284 is a 16-channel, constant-current sink light-emitting diode (LED) driver.

Each channel can be individually controlled with a simple serial communications protocol that is compatible with 3.3-V or 5-V CMOS logic levels, depending on the operating VCC.

When the serial data buffer is loaded, a LAT rising edge transfers the data to the OUTn outputs.
