• Manufacturer Part Number: STP08CDC596
• Description: 8-BIT CONSTANT CURRENT LED SINK DRIVER WITH FULL OUTPUT DETECTION
• Manufacturer: STMicroelectronics

STP08CDC596
The LEDs status will be detected al least in 2
microseconds and after this time the micro
controller puts OE in HIGH state and the output
data detection result will go to the microprocessor
via SDO.

The detection data format is the same of data in
normal mode. As soon as all the detection data
bits are available on the serial line, the device may
go back to normal mode operation.
