16-bit translating I²C-bus/SMBus I/O expander with interrupt, reset and agile I/O configuration

The TCAL6416 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 P-port side (VCCP).

The device supports 100kHz

(Standard-mode), 400kHz (Fast-mode), and 1MHz (fast-mode-plus) I2C clock

frequencies. I/O expanders such as the TCAL6416 provide

a simple solution when additional I/Os are needed for switches, sensors,

push-buttons, LEDs, fans, etc.

The TCAL6416 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 pull-down resistors, latchable inputs, maskable interrupt, interrupt status

register, and programmable open-drain or push-pull outputs.
