NCT5655Y/W
1. GENERAL DESCRIPTION
The NCT5655Y/W is a general purpose input/output IC with I2C-bus/SMBus that provides 16 bits of
General Purpose Input/Output (GPIO) expansion. The GPIO expanders provide a simple solution
when additional I/O is needed for push buttons, flashing LED output, BEEP functions, sensors and so
on. It also provides an interrupt to inform the system master when a transistion occurs on general
purpose input pins.
The NCT5655Y/W provides I2C-bus/SMBus address setting pins to set the address during power-on
reset or from external reset, allowing up to eight devices to share the same I2C-bus/SMBus.

When an I/O is configured as an input (default), FETs Q1 and Q2 are off, creating a high-impedance
input with a weak pull-up to VDD. The input voltage may be raised above VDD to a maximum of 5.5 V.
If the I/O is configured as an output, then either Q1 or Q2 is on, depending on the state of the Output
Port register. Care should be exercised if an external voltage is applied to an I/O configured as an
output because of the low-impedance path that exists between the pin and either VDD or VSS.
