It is 5V compliant, which means you can control it from a 3.3V microcontroller and still safely drive up to 6V outputs (this is good for when you want to control white or blue LEDs with 3.4+ forward voltages) 6 address select pins so you can wire up to 62 of these on a single i2c bus, a total of 992 outputs Output enable pin to quickly disable all the outputs Adjustable frequency PWM up to about 1.6 KHz.Configurable push-pull or open-drain output 12-bit resolution for each output - for servos, that means about 4us resolution at 60Hz update rate
