16-BIT CONSTANT CURRENT LED DRIVER with SHIFT REGISTER AND LATCH  
DESCRIPTION  
PIN CONFIGURATION (TOP VIEW)  
The M66503A is a constant current LED driver IC, whose  
output current is variable. The IC’s functions include 16-bit  
serial input/parallel output shift register with output latch.  
The product uses Bi-CMOS process for highly accurate con-  
stant current driving, permitting high-efficiency LED driving  
without using a resistor that limits LED current.  
Settings for the LED drive current are made by an external re-  
sister, thereby ensuring a maximum output current of 30 mA,  
enough for anode-common LED driving.

FUNCTION

PARALLEL DATA  
OUTPUT  
The M66503A is a constant current LED driver for anode-  
common LEDs. To set the LED driving current, an external  
resistor is connected between the current setting input pin,  
RC, and GND. In this way it is possible to set a highly accu-  
rate drive current. Each bit of the shift register is made up of a  
flip-flop performing shift function and a latch connected to the  
output. When the clock input pin, CKS, goes from “L” to “H”,  
data is shifted. Serial data is entered to the shift register via  
the serial data input pin, A. Data on A is straight shifted. By  
turning the latch enable input pin, LE, to “L”, the contents  
stored in the shift register is latched. All outputs are turned off  
if the output enable input pins, OEA and OEB, are simulta-  
neously set to “L”. This function is useful for the prevention of  
an excessive current flowing at the moment of power on. All  
outputs are turned on if the OEA pin is set to “H”. This enables  
to check LEDs for failure. In these actions, changing the state  
of OEA and/or OEB does not affect the shift function. To ex-  
pand the number of bits, link the M66503A in serial using the  
serial data output pin, SQ15, which is the serial data output  
of the shift register.
