DESCRIPTION  
30-MHz Data Transfer Rate (Standalone)  
15-MHz Data Transfer Rate (Cascaded Devices,  
SCLK Duty = 50%)  
The TLC5947 is a 24-channel, constant current sink  
LED driver. Each channel is individually adjustable  
with 4096 pulse-width modulated (PWM) steps. PWM  
control is repeated automatically with the  
programmed grayscale (GS) data. GS data are  
written via a serial interface port. The current value of  
all 24 channels is set by a single external resistor.  
Shift Out Data Changes With Falling Edge to  
Avoid Data Shift Errors  
Auto Display Repeat  
4-MHz Internal Oscillator  
Thermal Shutdown (TSD):  
The TLC5947 has a thermal shutdown (TSD) function  
that turns off all output drivers during an  
over-temperature condition. All of the output drivers  
automatically restart when the temperature returns to  
normal conditions.
