1 Features

• Operating power-supply voltage range of 1.08V to

3.6V

• Low standby current consumption of 1μA typical at

1.8mV

• 1MHz fast mode plus I2C bus

• Hardware address pin allows two devices on the

same I2C, SMBus bus

• Active-low reset input (RESET )

– Sticky registers retain values when device is

reset with RESET

– I2C functional state machine is reset

• Open-drain active-low interrupt output (INT )

• Input or output configuration register

• Polarity inversion register

• Configurable I/O drive strength register

• Pull-up and pull-down resistor configuration

register

• Internal power-on reset

• Noise filter on SCL or SDA inputs

• Latched outputs with high-current drive maximum

capability for directly driving LEDs

• Latch-up performance exceeds 100mA per JESD

78, class II

• ESD protection exceeds JESD 22

– 2000V Human-body model (A114-A)

– 1000V Charged-device model (C101)

3 Description

The TCAL9539R device provides general purpose

parallel input/output (I/O) expansion for the two-line

bidirectional I2C bus (or SMBus) protocol and is

designed for 1.08V to 3.6V VCC operation.

The device supports 100kHz (Standard-mode),

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

I2C clock frequencies. I/O expanders such as the

TCAL9539R provide a simple solution when additional

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

LEDs, fans, and so on.

The TCAL9539R 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.

The RESET pin only resets the I2C state machine

when stuck to regain access to the I2C. I/O pins and

sticky registers retain the last configured state while

the I2C is being re-initialized.
