PCA9536D118 Description

Short technical summary and product information.

The PCA9536D118 is a 4-bit I2C-bus and SMBus I/O port from NXP Semiconductors. It provides four GPIO pins that can be configured as inputs or outputs. The device operates from a supply voltage range of 2.3V to 5.5V and features 5V tolerant I/Os. The I/O pins include internal 100kΩ pull-up resistors and default to inputs. The I2C-bus interface supports clock frequencies from 0 Hz to 400 kHz. The device incorporates ESD protection exceeding 2000V HBM, 200V MM, and 1000V CDM, making it suitable for robust applications. This I/O expander is ideal for adding extra digital I/O lines in systems where only a limited number of GPIO pins are available on the microcontroller.
