RFQ ListingInterface ICs
The PCA9535BS,118 is a 16-bit I²C/SMBus GPIO expander in a compact 4×4 mm HVQFN, with 5 V tolerant I/O letting a 3.3 V-powered device interface with 5 V logic signals directly. Three hardware address pins allow up to 8 devices to share one I²C bus, and an INT output flags input changes without constant host polling.
