MAX6969AUG+ (MAXIM INTEGRATED PRODUCTS)

The MAX6969AUG+ is a 16 port, 5.5V constant current LED driver in 24 pin TSSOP package. This serial interfaced LED driver provides 16 open-drain, constant current sinking LED driver outputs rated at 5.5V. The device supply and the LED's supplies can power-up in any order. The constant current outputs are programmed together to up to 55mA using a single external resistor. The MAX6969 uses industry standard shift register and latch type serial interface. The driver accepts data shifted into a 16bit shift register using data input DIN and clock input CLK. The latch enable input (LE) loads 16bits of shift register data into 16bit output latch to set which LEDs are on and which are off. The output enable (OE) gates all 16 outputs on/off and is fast enough to be used as a PWM input for LED intensity control. The MAX6969 is used in variable message signs, marquee displays, point of order signs, traffic signals, gaming and architectural lighting applications.
