TLC59282DBQR

The TLC59282DBQR is a versatile 16-channel constant-current sink driver that offers precise control over individual channels through a serial communications protocol. With compatibility for both 3.3V and 5V CMOS logic levels, this device can be easily integrated into a variety of applications. The ability to cascade multiple TLC59282s enables users to expand their LED control capabilities without the need for additional complexity. Furthermore, the inclusion of a BLANK pin allows for convenient power-on and latching control, ensuring that unwanted displays are avoided during critical times. By utilizing a single external resistor, users can set the constant-current value for all 16 channels, simplifying the configuration process
