I/o Expanders Procurement Notes

Verify the specific ordering code PCA6408APW,118 against official NXP documentation to ensure correct package type and electrical specifications. Confirm that the 16-TSSOP variant matches your board layout requirements. Cross-reference the datasheet for exact pinout definitions and operating conditions before finalizing procurement decisions.

I/o Expanders Selection Notes

Select this component when an 8-bit I/O expander is required for I²C or SMBus communication. Ensure the design accommodates the 1.65 V to 5.5 V supply range and the 16-pin TSSOP footprint. Consider the interrupt output feature if asynchronous notification of I/O changes is necessary for the target application architecture.

I/o Expanders Part Context

This part belongs to the PCA6408A series of general-purpose I/O expanders from NXP Semiconductors. It is specifically engineered to extend the I/O capabilities of microcontrollers over the I²C-bus interface. The APW suffix denotes the 16-lead thin-shrink small-outline package (TSSOP) configuration.
