R8A66160DD/SP
16-BIT LED DRIVER WITH SHIFT REGISTER AND LATCH
DESCRIPTION
R8A66160 is a LED array driver having a 16-bit serial input and parallel output shift register function with
direct coupled reset input and output latch function.
This product guarantees the output current of 24mA (Vcc =5V case) which is sufficient for cathode common
LED drive, capable of following 16-bits continuously at the same time. Parallel output is open drain output.
In addition, as this product has been designed in complete CMOS, power consumption can be greatly
reduced when compared with conventional BIPOLAR or Bi-CMOS products. Furthermore, pin layout ensures
the realization of an easy printed circuit. R8A66160 is the succession product of M66310.
FEATURES
● Cathode common LED drive
● VCC 5V or 3.3V single power supply
● High output current: all parallel outputs QA~QP IOH=-24mA (at VCC =5.0V) IOH=-12mA (at VCC =3.3V)
simultaneous lighting available
● Low power dissipation: 100uW/package (max) (Vcc=5.0V, Ta=25oC, quiescent state)
● High noise margin: Schmitt input circuit provides responsiveness to a long line length
● Equipped with direct-coupled reset
● Open drain output: (except serial data output SQP)
● Wide operating temperature range: Ta=-40oC~+85oC
● Pin layout facilitates printed circuit wiring. (This layout facilitates cascade connection and LED connection)
APPLICATION
● LED array drive, The various LED display modules
● PPC, Printer, VCR, Mini-compo, Button-Telephone etc. All of LED display equipment

FUNCTIONAL DESCRIPTION
As R8A66160 uses silicon gate CMOS process. It realizes high-speed and high-output currents sufficient for
LED drive while maintaining low power consumption and allowance for high noises.
Each bit of a shift register consists of two flip-flop having independent clocks for shifting and latching.
As for clock input, shift clock input CKS and latch clock input CKL are independent from each other, shift and
latch operations being made when “L” changes to “H”.
Serial data input A is the data input of the first-step shift register and the signal of A shifts shifting registers
one by one when a pulse is impressed to CKS. When A is “L”, the signal of “L” shifts.
When the pulse is impressed to CKL, the contents of the shifting register at that time are stored in a latching
register, and they appear in the parallel data outputs from QA ~ QP.
Outputs QA ~ QP are open drain outputs.
To extend the number of bits, use the serial data output SQP which shows the output of the shifting register
of the 16th bit.
When reset input R is changed to “L”, QA ~ QP and SQP are reset. In this case, shifting and latching register
are reset.
If “H” is impressed to output enable input OE, QA ~ QP reaches the high impedance state, but SQP does not
reach the high impedance state. Furthermore, change in OE does not affect shift operation.
