The is a 8-port, 36V constant current LED driver in 16 pin TSSOP package. This serial interfaced LED driver provides eight open-drain, constant-current-sinking LED driver outputs rated at 36V. The constant current outputs are programmed together up to 55mA using a single external resistor and operates with a 25Mbps, industry standard, 4-wire serial interface. It uses industry-standard shift-registerplus latch-type serial interface. The driver accepts data shifted into an 8bit shift register using data input DIN and clock input CLK. Input data appears at output DOUT eight clock cycles later to allow cascading of multiple MAX6970"s. It is used for variable message signs, marquee displays, point of order signs, traffic signs, gaming features and architectural lighting.
