PCA9535PW,118 in I/O expanders Family
The PCA9535PW,118 family represents a series of 16-bit I2C and SMBus I/O expanders manufactured by NXP Semiconductors. These devices provide a cost-effective solution for expanding the General Purpose Input/Output capabilities of microcontrollers via a two-wire interface. Operating within a 2.3V to 5.5V range, they feature low standby current and an open-drain interrupt output that signals the host controller when input states change, eliminating the need for constant polling in low-power embedded designs.
Variants in This Sub-Family
Variants within this sub-family primarily differ in their physical packaging, such as TSSOP24 or HVQFN24, and their specific I2C address ranges. While the core 16-bit architecture remains consistent, some iterations like the 'A' or 'C' versions may offer different power-on reset thresholds or drive strengths. Tape and reel versus tube delivery formats are denoted by specific suffixes like ',118', which specifies high-volume automated assembly packaging.
