3 Description

The TCAL9538 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. I/O expanders such as the

TCAL9538 provide a simple solution when additional

I/Os are needed for switches, sensors, push-buttons,

LEDs, fans, and so on.

The TCAL9538 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.
