The PCAL6408APWJ from NXP Semiconductors is an 8-bit general-purpose I/O expander designed for remote I/O expansion via the I2C-bus interface. It is suitable for battery-powered mobile applications and simplifies interconnections between microcontrollers and peripherals operating at different voltage levels due to its built-in level shifting feature.
This I/O expander operates with a wide VDD range of 1.65 V to 5.5 V, allowing seamless communication with both low-voltage microprocessors and higher-voltage peripherals. It supports I2C and SMBus interfaces with a clock frequency of up to 400 kHz. The device offers 8 I/O channels with open-drain and push-pull output types.
Packaged in a 16-TSSOP, the PCAL6408APWJ is designed for surface mount applications. It operates within a temperature range of -40°C to 85°C. Additional features include an interrupt output and POR (Power-On Reset).
The PCAL6408APWJ contains configurable registers for I/O direction, output state, and polarity inversion. It also includes Agile I/O features such as programmable output drive strength, latchable inputs, programmable pull-up/pull-down resistors, and a maskable interrupt.
