    Feature:
    1MHz Fast-mode Plus compatible owned 30mA high drive capability on SDA of I2C bus interface to drive highly capacitive bus
    Each LED output can be achieved from the fully closed (default) to 4096 (12) between the maximum brightness linear programmable brightness
    Software programmable open-drain LED output selection (default is push-pull) of 16 push-pull outputs (5V at 25mA sink can absorb and provide 10mA Source Current), no input function
    Programmable output state is in response to an order to change or stop in order to achieve all outputs simultaneously update or byte by byte (byte-by-byte) update output (default "Stop command changes")
    Active-low output enable input pin when the pin is high LED outputs can be programmed 0,1 or tri-state (high impedance power-on default)
    6 hardware address pins so that the same I2C devices can be connected to the bus 62 PCA9685
    LED output frequency (all LED) is typically 40Hz to 1000Hz (When the oscillator is 25MHz, the prescaler register default value 1EH will generate refresh rate of 200Hz)
    4 software-programmable I2C bus address (a LED group call (Call) addresses and three LED sub call (Call) address) so that the device can be set in any combination to be addressed at the same time (for example, a register for " all calls (All Call) "then all PCA9634 devices on the I2C bus can be addressed at the same time, while the second register for three different addresses, then the device group on a bus device can 1/3 at the same time be addressed), software can enable and disable I2C bus address
    Software reset feature (SWRST Call) makes the device via the I2C bus reset
    25MHz internal oscillator requires no external components
    The maximum allowable 50MHz external clock input
    An internal power-on reset
    In the SDA / SCL inputs with noise filter
    Output pin has edge generation rate control
    No glitches on power output
    Hot-Access
    Low Standby Current
    Operating voltage range: 2.3V to 5.5V
    5.5V tolerant inputs
    It can operate at minus 40 degrees Celsius to 85 degrees Celsius environment
    ESD protection exceeds 2000V HBM / JESD22-A114,200V MM / JESD22-A115 and 1000V CDM / JESD22-C101
    JEDEC standard JESD78 into the lock test beyond 100mA
