PCA9704 Datasheet

Features and benefits


* 8 general purpose input ports
* 18 V tolerant input ports with 100 k external series resistor
* Input LOW threshold 0.55  VDD with minimum of 2.5 V at VDD.

Application

Higher voltages can be tolerated on the inputs depending on the series resistor used to limit the input current. The IN.

Description

The PCA9704 is a low power 18 V tolerant SPI General Purpose Input (GPI) shift register designed to monitor the status of switch inputs. It generates an interrupt when one or more of the switch inputs change state but allows selected inputs to not ge.
