The PCA9703PW/Q900,118 from NXP Semiconductors is an 18V tolerant SPI General Purpose Input (GPI) shift register designed for monitoring switch inputs. It can monitor up to 16 switch inputs and generates an interrupt when input states change, with an interrupt masking feature to disable specific inputs.
This device operates with a supply voltage range of 4.5V to 5.5V and supports SPI serial interface speeds up to 5 MHz. The input ports are 18V tolerant, especially when used with a 100 k external series resistor, making them suitable for automotive applications. The input LOW threshold is 0.55 x VDD, with a minimum of 2.5V at 4.5V VDD.
The PCA9703PW/Q900,118 is offered in a 24-TSSOP package and is suitable for surface mount applications. It features an open-drain interrupt output and an interrupt enable pin to minimize battery drain. The device also supports daisy-chain connections for expanding switch monitoring capabilities.
Key features include 16 general purpose input ports, 18V tolerant inputs, and an operating temperature range of -40°C to +125°C. This makes it a versatile component for automotive and mobile applications.
