The PCA9500BS omits these features but is otherwise pin-compatible and functionally identical for basic GPIO expansion. If you need non-volatile storage for configuration or a clean power-up state without an external supervisor, choose the PCA9501BS; otherwise, the PCA9500BS is a cost-reduced alternative."},{"question":"Is PCA9501BS compatible with 3.3V logic?","answer":"Yes. The supply voltage range of 2.5V to 3.6V covers the 3.3V rail directly. The I2C and GPIO pins are 3.3V-tolerant, so no level shifter is needed when the host microcontroller runs at 3.3V."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/nxp/PCA9501BS118","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/nxp/PCA9501BS118 when reusing this data.
