PCA9704 Product details

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.

Features

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 = 4.5 V.
Open-drain interrupt output.
Interrupt enable pin (INT_EN) disables GPI pins and interrupt output.
Interrupt-masking feature allows no interrupt generation from selected inputs.
VDD range: 4.5 V to 5.5 V.
IDD is very low 2.5 A maximum.
SPI serial interface with speeds up to 5 MHz.
SP.
