The PCA9701/PCA9702 are 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. The input level is recognized as a HIGH when it is greater than 0.7 VDD and as a LOW when it is less than 0.4 VDD (minimum threshold o.
16 general purpose input ports (PCA9701) or 8 general purpose input ports (PCA9702)
18 V tolerant input ports with 100 k external series resistor
Input LOW threshold 0.4 VDD with minimum of 2 V at VDD = 4.5 V
Open-drain interrupt output
Interrupt enable pin (INT_EN) disables interrupt output
VDD range: 2.5 V to 5.5 V
