Low Power I/O Expander

Low Power I/O Expander 24-Pin QFN EP T/R

Manufacturer Part #: PCA9535EMTTXG

Alternate Part #: PCA9535EMTTXG/BKN

The PCA9535E and PCA9535EC devices provide 16 bits of General Purpose parallel Input/Output(GPIO) expansion through the ICbus/SMBus. The PCA9535E and PCA9535EC consist of two 8bit Configuration Input or Output selection. Input, Output and Polarity Inversion (active HIGH or active LOW operation) registers. At power on, all I/Os default to inputs. Each I/O may be configured as either input or output by writing to its corresponding I/O configuration bit.
