Manufacturer

Description

This 16-bit I/O expander for the two-line bidirectional bus (I2C) is designed for 2.3-V to 5.5-V VCC operation. It provides general-purpose remote I/O expansion for most microcontroller families via the I2C interface [serial clock (SCL), serial data (SDA)].The PCA9555DGVR consists of two 8-bit Configuration (input or output selection), Input Port, Output Port, and Polarity Inversion (active high or active low operation) registers. At power on, the I/Os are configured as inputs. The system master can enable the I/Os as either inputs or outputs by writing to the I/O configuration bits. The data for each input or output is kept in the corresponding Input or Output register. The polarity of the Input Port register can be inverted with the Polarity Inversion register. All registers can be read by the system master. PCA9555DGVR Features • Low Standby-Current Consumption of 1 mA Max• Open-Drain Active-Low Interrupt Output• 5-V Tolerant I/O Ports• Compatible With Most Microcontrollers• Polarity Inversion Register• Latched Outputs With High-Current Drive Capability for Directly Driving LEDs• Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II
