PIN DESCRIPTIONS
VCC
is the supply input for the internal logic
and is compatible with both 3.3V and 5V
systems. The logic is held in a reset state until
VCC exceeds 2.5V. It is recommended that a
small bypass ceramic capacitor (1uF) be
placed between VCC and GND pins on the
device.
SIN
is the CMOS logic pin for delivering the
serial input data stream into the internal 10-bit
shift register. The most recent or last data
value in the serial stream is used to configure
the state of output channel “zero” (OUT0).
During the initial power up sequence all
contents of the shift register are reset and
cleared to zero.
SCLK
is the CMOS logic pin used to clock
the internal shift register. On each rising edge
of clock, the serial data will advance through
one stage of the shift register.
XLAT
is the CMOS logic input used to
transfer data from the 10-bit shift register into
the output channel latches. An internal pull-
down current of 10 microampere is present on
this pin. When XLAT is low, the state of each
output channel remains unchanged. When
XLAT is driven high, the contents of the shift
register appear at their respective output
channels. An external pull-up resistance of
10k
or less is adequate for logic high.
PGND, GND
pins should be connected to
the ground on the PCB.

N.C.
BLANK
is the CMOS logic input (active high)
used to temporarily disable all outputs. An
internal pull-up current of 10 microampere is
present on this pin. The BLANK pin must be
driven to a logic low in order for channel outputs
to resume normal operation. An external pull-
down resistance of 10k
or less is adequate for
logic low.
SOUT
is the CMOS logic output used for daisy
chain applications. The serial output data
stream is fed from the last stage of the internal
10-bit shift register. On each rising edge of the
clock, the SOUT value will be updated. The
data value present on this pin is identical to the
data value being used for configuring the state
of output channel nine (OUT9). At initial power
up, the SOUT data stream will contain all
zeroes until the shift register has been fully
loaded.
VBATT
input monitors the battery voltage. If an
over-voltage, above 19V typical, is detected, all
outputs are disabled. Upon conclusion of the
over-voltage condition, all outputs resume
normal operation. The current drawn by the
VBATT pin is less than 1 microampere during
normal operation.
OUT0-OUT9
are the ten LED outputs
connected internally to the switch N-channel
FETs. They sink currents up to 50mA per
channel and can withstand transients up to 40V
compatible with automotive “l(fā)oad dump”. The
output on-resistance is 5
, and the off-
resistance is 5M
.
