ZQL9712 chip is specially designed for LED drives applications, and adopt advanced CMOS craft with the advantage of low consumption. The ZQL9712 chip can apply to the LED display system, especially suits the multi-separate dots cascade applies. ZQL9712 supplies 3 pieces of large electric current to drive and output, drive the 30MA most greatly of electric current. ZQL9712 chip including serial-shift register and output latch, Which is through serial-shift register with 3bits parallel output, take this output as the input of the output register at the meantime. The serial-shift register and the output register are controlled by the different clock signal , and all is effective in the clock signal rise The driven control-signal can be taken as the input signal of the back cascade circuit after it outputted by ZQL9712. ,
Features * bits drive output. 3 * maximum output current is up to 30 MA. the * Optimized interface with many slice trans-board cascade. * CMOS level input compatible. 5V
