TCAL9539-Q1
Description
The TCAL9539-Q1 device provides general purpose parallel input/output (I/O) expansion for the two-line bidirectional I2C bus (or SMBus) protocol and is designed for 1.08-V to 3.6-V VCC operation. The device supports 100-kHz (Standard-mode), 400-kHz (Fast-mode), and 1-MHz (fast-mode-plus) I2C clock frequencies.
