TCA6408A Overview
Key Specifications
Package: VQFN
Pins: 16
Max Voltage (typical range): 5.5 V
Min Voltage (typical range): 1.65 V
Description
The TCA6408A is a 16-pin device that provides 8-bits of general purpose parallel input/output (I/O) expansion for the two-line bidirectional I2C bus (or SMBus) protocol. This device can operate with a power supply voltage ranging from 1.65 V to 5.5 V on both the I2C bus side (VCCI) and on the P-port side (VCCP).
Key Features
