PCA9701; PCA9702  
18 V tolerant SPI 16-bit/8-bit GPI with INT  
Rev. 7 — 26 September 2014  
Product data sheet  
1. General description  
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 of 2 V at 5 V node). The PCA9701 can monitor up to 16 switch inputs  
and the PCA9702 can monitor up to 8 switch inputs.  
The falling edge of the CS pin samples the input port status and clears the interrupt. When  
CS is LOW, the rising edge of the SCLK loads the shift register and shifts the value out of  
the shift register. The serial input is sampled on the falling edge of SCLK.  
Each of the input ports has a 18 V breakdown ESD protection circuit. When used with a  
series resistor (minimum 100 k), the input can connect to a 12 V battery and support  
double battery, reverse battery, 27 V jump start and 40 V load dump conditions in  
automotive applications. Higher voltages can be tolerated on the inputs depending on the  
series resistor used to limit the input current.  
With both the high breakdown voltage and high ESD, these devices are useful for both  
automotive and mobile applications.  
The PCA9703/PCA9704 are new pin compatible devices for the PCA9701/PCA9702  
which have an interrupt masking feature allowing selected inputs to not generate  
interrupts and provides higher ground offset of 0.55 VDD (minimum of 2.5 V at 5 V node)  
with minimum hysteresis of 0.05 VDD (minimum of 225 mV at 5 V node).  
2. Features and benefits  
16 general purpose input ports (PCA9701) or 8 general purpose input ports  
(PCA9702)  
18 V tolerant input ports with 100 kexternal 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  
IDD is very low 2.5 A maximum  
SPI serial interface with speeds up to 5 MHz  
ESD protection exceeds 8 kV HBM per JESD22-A114, 350 V MM, and 1000 V CDM  
per JESD22-C101  
Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA  
Operating temperature range: 40 C to +125 C
