Status: active
The PCF8574AN is marked as ACTIVE and recommended for new designs by TI. Recent datasheet maintenance (Revision H, September 2024) confirms ongoing engineering support. Multiple authorized distributors (Mouser, Newark, Element14, Farnell, Digi-Key) stock the part, and no EOL announcement, NRND status, or successor part has been published. This is a mature legacy I2C I/O expander with strong supply chain coverage and no announced lifecycle transition.
