Texas Instruments TCAL6408
The TCAL6408 device provides general purpose parallel input/output (I/O) expansion for the two-line bidirectional I2C bus (or SMBus) protocol. The device can operate with a power supply voltage ranging from 1.08V to 3.6V on the I2C bus side (VCCI) and a power supply voltage ranging from 1.08V to 3.6V on the Pport side (VCCP). The device supports 100kHz (Standard-mode), 400kHz (Fast-mode), and 1MHz (fast-mode-plus) I2C clock frequencies.| Part No. | TCAL6408 |
