8-Port, 5.5V Constant-Current LED Driver
General Description
The MAX6968 serial-interfaced LED driver provides
eight open-drain, constant-current sinking LED driver
outputs rated at 5.5V. The MAX6968 operates from a 3V
to 5.5V supply. The MAX6968 supply and the LEDs’
supply or supplies may power up in any order. The
constant-current outputs are programmed together to
up to 55mA using a single external resistor. The
MAX6968 operates with a 25Mb, industry-standard, 4-
wire serial interface.
The MAX6968 uses the industry-standard shift-register-
plus-latch-type serial interface. The driver accepts data
shifted into an 8-bit shift register using data input DIN
and clock input CLK. Input data appears at the output
DOUT eight clock cycles later to allow cascading of
multiple MAX6968s. The latch-enable input LE loads
the 8 bits of shift register data into an 8-bit output latch
to set which LEDs are on and which are off. The output-
enable input OE gates all eight outputs on and off, and

Ordering Information
is fast enough to be used as a PWM input for LED
intensity control.
For applications requiring LED fault detection, refer to
the MAX6977 data sheet that automatically detects
open-circuit LEDs.
For safety-related applications requiring a watchdog

timer, refer to the MAX6978 data sheet that includes a
fail-safe feature that blanks the display if the serial inter-
face becomes inactive for more than 1s.
The MAX6968 is one of a family of 12 shift-register-plus-
latch-type LED drivers. The family includes 8-port and
16-port types, with 5.5V- or 36V-rated LED outputs, with
and without open-circuit LED detection and watchdog.
All versions operate from a 3V to 5.5V supply, and are
