The 400 kHz clock keeps the bus transaction time under 40 µs for a full read-write cycle, so the expander does not stall the I²C bus on a mixed-speed network. ## Supply voltage, temperature, and the POR feature The POR (power-on reset) feature ensures all registers default to a known state at power-up, so the outputs do not glitch high before the microcontroller configures them. ## Package, mounting, and sourcing posture Housed in an 8-SOIC (3.90 mm width) package with surface-mount mounting — a standard footprint that reflows on a basic SMT line. The part is Active and ROHS3 compliant.","metaTitle":"NXP PCA9536D,118 I2C I/O Expander, 4 GPIO, 8-SOIC","metaDescription":"NXP PCA9536D,118 I2C/SMBus I/O expander, 4 GPIO, 400 kHz, 2.3-5.5 V supply, -40 to +85 °C, 8-SOIC.
