I am using 74HC595 Shift Registers (two) and TLC59116 to drive 16x16 LED matrix. One LED will be on at time. The current requirement is low, less than 5 mA. It works fine for me. Now I want to drive dual color, two pins LED matrix by same configuration. I am thinking to use 74HC595 ( four) - two for each color and two TLC59116 - one each color. The 74HC595 has OE enable, which make in tri-state so I can use pair based on color requirement but TLC59116 does not have enable pin. How to handle this? One hint in datasheet - disable clock or switch off outputs using zero duty cycle. But it is not written in ds, what will happen in these case, does still there will be sink? Does it create any problem or any better method is available.
One method from ASM AS1130, but I am want use TLC59116 which already used and familiar with it.
Please comment
Thanks in Advance.
