MAX6969AUG+T

MAX6969AUG+T is a 16-port, 5.5V constant-current LED driver. The MAX6969 uses the industry-standard, shift-register plus-latch-type serial interface. The driver accepts data shifted into a 16-bit shift register using data input DIN and clock input CLK. Input data appears at the DOUT output 16 clock cycles later to allow cascading of multiple MAX6969s. The latch-enable input, LE, loads the 16 bits of shift register data into a 16-bit output latch to set which LEDs are on and which are off. Suitable for variable message signs, marquee displays, p point of-order signs, traffic signs, gaming features and architectural lighting applications.
