Pin Functions

DESCRIPTION
I
Shift register clear, active-low. The storage register transfers data to the output buffer
when CLR is high. Driving CLR low clears all the registers in the device.
O
Open-drain output, LED current-sink channel, connect to LED cathode

I
Output enable, active-low. LED-channel enable and disable input pin. Having G low
enables all drain channels according to the output-latch register content. When high, all
channels are off.
—
Power ground, the ground reference pin for the device. This pin must connect to the
ground plane on the PCB.
I
Register clock. The data in each shift register stage transfers to the storage register at the
rising edge of RCK.
I
Serial data input. Data on SER IN loads into the internal register on each rising edge of
SRCK.
O
Serial data output of the 8-bit serial shift register. The purpose of this pin is to cascade
several devices on the serial bus.
I
Serial clock input. On each rising SRCK edge, data transfers from SER IN to the internal
serial shift registers.
I
Power supply pin for the device. TI recommends adding a 0.1-μF ceramic capacitor close
to the pin.
