M66311P/FP
16-Bit LED Driver with Shift Register and Latch
REJ03F0177-0201
Rev.2.01
Mar 31, 2008
Description
M66311P/FP is a LED array driver having a 16 bit serial-input and parallel output shiftregister function with direct
coupled reset input and output latch function.
This product guarantees the output electric current of 24 mA which is sufficient for anode common LED drive, capable
of flowing 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 lay–out ensures the realization of an easy printed circuit.
Features
• Anode common LED drive
• High output current all parallel output IOL = 24 mA simultaneous lighting available
• Low power dissipation: 100 µW/package (max)
(VCC = 5 V, Ta = 25°C, 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)
• Wide operating temperature range: Ta = −40 to +85°C
• Pin lay-out facilitates printed circuit wiring. (This lay-out facilitates cascade connection and LED connection.)
Application
LED array drive of BUTTON TELEPHONE
LED array drive of ERASER of a PPC copier
Other various LED modules

M66311P/FP
Functional Description
As M66311P/FP 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 shiftregister consists of two flip–flops 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 shiftregister and the signal of A shifts shifting registers one by one
when a pulse is impressed to CKS. When A is “H”, 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 outputs from QA to QP.
Outputs from QA to 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.
If CKS and CKL are connected, the state of the shifting register with one clock delay is outputted to QA to QP.
When reset input R is changed to “L”, QA to QP and SQP are reset. In this case, shifting and latching registers are set.
If “H” is impressed to output enable input OE, QA to QP reaches the high impedance state, but SQP does not reach the
high impedance state. Furthermore, change in OE does not affect shift operation.
