I C/SMBus applications and was developed to enhance the Philips
2
family of I C I/O expanders. The improvements include higher drive
capability, 5 V I/O tolerance, lower supply current, individual I/O
configuration, and smaller packaging. I/O expanders provide a
simple solution when additional I/O is needed for ACPI power
switches, sensors, pushbuttons, LEDs, fans, etc.
The PCA9535 consist of two 8-bit Configuration (Input or Output
selection); Input, Output and Polarity inversion (Active HIGH or
Active LOW operation) registers. The system master can enable the
I/Os as either inputs or outputs by writing to the I/O configuration
bits. The data for each Input or Output is kept in the corresponding
Input or Output register. The polarity of the read register can be
inverted with the Polarity Inversion Register. All registers can be
read by the system master. Although pin-to-pin and I C address
compatible with the PCF8575, software changes are required due to
the enhancements and are discussed in Application Note AN469.
FEATURES
• Operating power supply voltage range of 2.3 V-5.5 V
• 5 V tolerant I/Os
• Polarity inversion register
• Active LOW interrupt output
• Low stand-by current
2
The PCA9535 is identical to the PCA9555 except for the removal of
the internal I/O pull-up resistor which greatly reduces power
consumption when the I/Os are held LOW.
• Noise filter on SCL/SDA inputs
• No glitch on power-up
• Internal power-on reset
The PCA9535 open-drain interrupt output is activated when any
input state differs from its corresponding input port register state and
is used to indicate to the system master that an input state has
changed. The power-on reset sets the registers to their default
values and initializes the device state machine.
• 16 I/O pins which default to 16 inputs
• 0 to 400 kHz clock frequency
2
Three hardware pins (A0, A1, A2) vary the fixed I C address and
2
allow up to eight devices to share the same I C/SMBus. The fixed
• ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V
2
I C address of the PCA9535 is the same as the PCA9554 allowing
MM per JESD22-A115, and 1000 V CDM per JESD22-C101
up to eight of these devices in any combination to share the same
I C/SMBus.
• Latch-up testing is done to JESDEC Standard JESD78 which
2
exceeds 100 mA
• Offered in three different packages: SO24, TSSOP24, and
HVQFN24

Figure 4. Simplified schematic of I/Os
I/O port
When an I/O is configured as an input, FETs Q1 and Q2 are off,
creating a high impedance input. The input voltage may be raised
above V to a maximum of 5.5 V.
DD
If the I/O is configured as an output, then either Q1 or Q2 is on,
depending on the state of the Output Port register. Care should be
exercised if an external voltage is applied to an I/O configured as an
output because of the low impedance path that exists between the
pin and either V or V
.

The command byte is the first byte to follow the address byte during
a write transmission. It is used as a pointer to determine which of the
following registers will be written or read.
Figure 5. PCA9535 address
BUS TRANSACTIONS
Registers 0 and 1 — Input Port Registers
Writing to the port registers
Data is transmitted to the PCA9535 by sending the device address
and setting the least significant bit to a logic 0 (see Figure 5 for
device address). The command byte is sent after the address and
determines which register will receive the data following the
command byte.
This register is an input-only port. It reflects the incoming logic levels
of the pins, regardless of whether the pin is defined as an input or an
output by Register 3. Writes to this register have no effect.
Registers 2 and 3 — Output Port Registers
The eight registers within the PCA9535 are configured to operate
as four register pairs. The four pairs are Input Ports, Output Ports,
Polarity Inversion Ports, and Configuration Ports. After sending data
to one register, the next data byte will be sent to the other register in
the pair (see Figures 6 and 7). For example, if the first byte is sent to
Output Port (register 3), then the next byte will be stored in Output
Port 0 (register 2). There is no limitation on the number of data bytes
sent in one write transmission. In this way, each 8-bit register may
be updated independently of the other registers.

This register is an output-only port. It reflects the outgoing logic
levels of the pins defined as outputs by Register 6 and 7. Bit values
in this register have no effect on pins defined as inputs. In turn,
reads from this register reflect the value that is in the flip-flop
controlling the output selection, NOT the actual pin value.
Reading the port registers
In order to read data from the PCA9535, the bus master must first
send the PCA9535 address with the least significant bit set to a
logic 0 (see Figure 5 for device address). The command byte is sent
after the address and determines which register will be accessed.
After a restart, the device address is sent again but this time, the
least significant bit is set to a logic 1. Data from the register defined
by the command byte will then be sent by the PCA9535 (see
Figures 8 , 9, and 10). Data is clocked into the register on the falling
edge of the acknowledge clock pulse. After the first byte is read,
additional bytes may be read but the data will now reflect the
information in the other register in the pair. For example, if you read
Input Port 1, then the next byte read would be Input Port 0. There is
no limitation on the number of data bytes received in one read
transmission but the final byte received, the bus master must not
acknowledge the data.

This register allows the user to invert the polarity of the Input Port
register data. If a bit in this register is set (written with ‘1’), the Input
Port data polarity is inverted. If a bit in this register is cleared (written
with a ‘0’), the Input Port data polarity is retained.

The open-drain interrupt output is activated when one of the port
pins change state and the pin is configured as an input. The
interrupt is deactivated when the input returns to its previous state or
the input port register is read (see Figure 9). A pin configured as an
output cannot cause an interrupt. Since each 8-bit port is read
independently, the interrupt caused by Port 0 will not be cleared by a
read of Port 1 or the other way around.

This register configures the directions of the I/O pins. If a bit in this
register is set (written with ‘1’), the corresponding port pin is enabled
as an input with high impedance output driver. If a bit in this register
is cleared (written with ‘0’), the corresponding port pin is enabled as
an output. At reset the device’s ports are inputs.
Note that changing an I/O from an output to an input may cause a
false interrupt to occur if the state of the pin does not match the
contents of the Input Port register.

When the I/Os are used to control LEDs, they are normally connected to V through a resistor as shown in Figure 11. Since the LED acts as a
DD
diode, when the LED is off the I/O V is about 1.2 V less than V . The supply current, I , increases as V becomes lower than V and is

Designs needing to minimize current consumption, such as battery power applications, should consider maintaining the I/O pins greater than or
equal to V when the LED is off. Figure 12 shows a high value resistor in parallel with the LED. Figure 13 shows V less than the LED supply
