L16B06
16-BIT CONSTANT CURRENT
LED DRIVER
CMOS IC
DESCRIPTION
The L16B06 is a constant-current sink driver specifically
designed for LED display applications. The device incorporates shift
registers, data latches, and constant current circuitry on the silicon
CMOS chip. The maximum output current value of all 16 channels is
adjustable by a single external resistor.
FEATURES
*Constant-current outputs: 3mA to 60mA adjustable by one external
resistor
*Maximum output voltage: 17V
*Maximum clock frequency: 25MHz
*Power supply voltage: 3.3V to 5V
*In-rush current control
*Bit-to-bit skew: ±3% Chip-to-chip skew: ±6%
*Package and pin assignment compatible to conventional LED
drivers
APPLICATIONS
*Indoor/Outdoor LED Video Display
*LED Variable Message Signs (VMS) System

FUNCTION
Ground terminal.
Serial data input terminal.
Synchronous clock input terminal for serial data transfer. Data is sampled at the rising
edge of DCK.
Input terminal of data strobe. Data on shift register goes through at the high level of LAT
(level trigger). Otherwise, data is latched.
Sink constant-current outputs (open-drain).
Output enable terminal:
‘H’ for all outputs are turned off,
‘L’ for all outputs are active.
Serial data output terminal.
External resistors connected between REXT and GND for output current value setting.
Supply voltage terminal.
