3 Description
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
1.08 V to 3.6 V on the I2C bus side (VCCI) and a
power supply voltage ranging from 1.08 V to 3.6 V on
the P-port side (VCCP).
The device supports 100-kHz (Standard-mode), 400-
kHz (Fast-mode), and 1-MHz (fast-mode-plus) I2C
clock frequencies. I/O expanders such as the
TCAL6408 provide a simple solution when additional
I/Os are needed for switches, sensors, push-buttons,
LEDs, fans, and so on.
The TCAL6408 has Agile I/O ports which include
additional features designed to enhance the I/O
performance in terms of speed, power consumption
and EMI. The additional features are: programmable
output drive strength, programmable pull-up and pulldown
resistors, latchable inputs, maskable interrupt,
interrupt status register, and programmable opendrain
or push-pull outputs.
