I/O expander, PCA9538DWR, Texas Instruments
The PCA9538DWR is an 8-bit I/O expander of general purpose parallel input and output (I/O) expansion for the two-line bidirectional I2C bus (or SMBus) protocol. This device can operate with a power supply range from 2.3 V to 5.5 V. This device supports both100-kHz (Standard-mode) and 400-kHz (Fast-mode) clock frequencies. This device, along with other I/O expanders, provides a simple solution when additional I/Os are needed for switches, sensors, push-buttons, LEDs, fans, and so on. The features of PCA9538DWR include an interrupt that is generated on the INT pin whenever an input port changes state.
Features
- Input and output configuration register
- Polarity inversion register
- Power-up with all channels configured as inputs
- No glitch on power up
- Latched outputs with high-current drive maximum capability for directly driving LEDs
