TERMINAL FUNCTION
SBVS137 – DECEMBER 2009
I/O
DESCRIPTION
Blank all outputs. When BLANK is high, all OUTn outputs are forced OFF.
I
GS counter is also reset. When BLANK is low, OUTn are controlled by the
grayscale PWM control.
G
Ground
I
Reference clock for grayscale PWM control
Reference current terminal. The maximum current for the outputs
I/O OUT0-OUT15 is set with a resistor from IREF to GND. Any capacitance does
not need to be connected between IREF and GND.
No connection
Constant-current output. Multiple outputs can be configured in parallel to
O
increase the constant-current capability. Different voltages can be applied to
each output.

I
Input mode-change pin. When MODE = GND, the device is in GS mode.
When MODE = VCC, the device is in DC mode.
O
Error output. XERR is an open-drain terminal. XERR goes low when LOD or
TEF is detected.
Level triggered latch signal. When XLAT is high, the TLC59401 writes data
I
from the input shift register to either GS register (MODE is low) or DC
register (MODE is high). When XLAT is low, the data in the GS or DC
registers are held constant and do not change.
