14 / 102 page ![]() Multiple Channel Capacitive Touch Sensor and LED Driver Datasheet Revision 1.1 (02-04-11) 14 SMSC CAP1114 DATASHEET The pin types are described in Table 2.2, "Pin Types". All pins labeled with (5V) are 5V tolerant. Note: For all 5V tolerant pins that require a pull-up resistor, the voltage difference between VDD and the pull-up voltage must never exceed 3.6V. 24 N/C Not Connected - connect to gnd N/A 25 N/C Not Connected - connect to gnd N/A 26 CS1 Capacitive Touch Sensor 1 AIO 27 CS2 Capacitive Touch Sensor 2 AIO 28 CS3 Capacitive Touch Sensor 3 AIO 29 CS4 Capacitive Touch Sensor 4 AIO 30 CS5 Capacitive Touch Sensor 5 AIO 31 CS6 Capacitive Touch Sensor 6 AIO 32 CS7 Capacitive Touch Sensor 7 AIO Bottom Plate GND Power Ground Power Table 2.2 Pin Types PIN TYPE DESCRIPTION Power This pin is used to supply power or ground to the device. DI Digital Input - this pin is used as a digital input. This pin is 5V tolerant. DIO Digital Input Output - this pin is used as a digital input / output. AIO Analog Input / Output - this pin is used as an I/O for analog signals. DIOD Digital Input / Open Drain Output - this pin is used as an digital I/O. When it is used as an output, It is open drain and requires a pull-up resistor. This pin is 5V tolerant. OD Open Drain Digital Output - this pin is used as a digital output. It is open drain and requires a pull-up resistor. This pin is 5V tolerant. DO Push-pull Digital Output - this pin is used as a digital output and can sink and source current.
