PCA9548
DESCRIPTION
The PCA9548 is a octal bi-directional translating switch controlled
by the I2C-bus. The SCL/SDA upstream pair fans out to eight
downstream pairs, or channels. Any individual SCx/SDx channel or
combination of channels can be selected, determined by the
contents of the programmable Control Register.
An active-LOW reset input allows the PCA9548 to recover from a
situation where one of the downstream I2C-buses is stuck in a LOW
state. Pulling the RESET pin LOW resets the I2C state machine and
causes all the channels to be deselected as does the internal power
on reset function.
FEATURES
• 1-of-8 bi-directional translating switches
• I2C interface logic; compatible with SMBus standards
• Active LOW Reset Input
• 3 address pins allowing up to 8 devices on the I2C-bus
• Channel selection via I2C-bus, in any combination
• Power-up with all switch channels deselected
• Low RdsON switches
• Allows voltage level translation between 1.8 V, 2.5 V, 3.3 V and
The pass gates of the switches are constructed such that the VDD
pin can be used to limit the maximum high voltage which will be
passed by the PCA9548. This allows the use of different bus
voltages on each pair, so that 1.8 V, 2.5 V, or 3.3 V parts can
communicate with 5 V parts without any additional protection.
External pull-up resistors pull the bus up to the desired voltage level
for each channel. All I/O pins are 5 V tolerant.

DEVICE ADDRESSING
Following a START condition the bus master must output the
address of the slave it is accessing. The address of the PCA9548 is
shown in Figure 3. To conserve power, no internal pullup resistors
are incorporated on the hardware selectable address pins and they
must be pulled HIGH or LOW.

Following the successful acknowledgement of the slave address,
the bus master will send a byte to the PCA9548, which will be stored
in the control register. If multiple bytes are received by the
PCA9548, it will save the last byte received. This register can be
written and read via the I2C-bus.

NOTE: Several channels can be enabled at the same time.
Ex: B7 = 0, B6 = 1, B5 = 0, B4 = 0, B3 = 1, B2 = 1, B1 = 0, B0 = 0,
means that channels 7, 5, 4, 1, and 0 are disabled and channels 6,
3, and 2 are enabled.
Care should be taken not to exceed the maximum bus capacitance.
CONTROL REGISTER DEFINITION
One or several SCx/SDx downstream pair, or channel, is selected
by the contents of the control register. This register is written after
the PCA9548 has been addressed. The 2 LSBs of the control byte
are used to determine which channel is to be selected. When a
channel is selected, the channel will become active after a stop
condition has been placed on the I2C-bus. This ensures that all
SCx/SDx lines will be in a HIGH state when the channel is made
active, so that no false conditions are generated at the time of
connection.
RESET INPUT
The RESET input is an active-LOW signal which may be used to
recover from a bus fault condition. By asserting this signal LOW for
a minimum of tWL, the PCA9548 will reset its registers and I2C state
machine and will deselect all channels. The RESET input must be
connected to VDD through a pull-up resistor.
POWER-ON RESET
When power is applied to VDD, an internal Power On Reset holds
the PCA9548 in a reset state until VDD has reached VPOR. At this
point, the reset condition is released and the PCA9548 registers and
I2C state machine are initialized to their default states, all zeroes
causing all the channels to be deselected.

Figure 5 shows the voltage characteristics of the pass gate
transistors (note that the PCA9548 is only tested at the points
specified in the DC Characteristics section of this datasheet). In
order for the PCA9548 to act as a voltage translator, the Vpass
voltage should be equal to, or lower than the lowest bus voltage. For
example, if the main bus was running at 5 V, and the downstream
buses were 3.3 V and 2.7 V, then Vpass should be equal to or below
2.7 V to effectively clamp the downstream bus voltages. Looking at
Figure 5, we see that Vpass (max.) will be at 2.7 V when the
PCA9548 supply voltage is 3.5 V or lower so the PCA9548 supply
voltage could be set to 3.3 V. Pull-up resistors can then be used to
bring the bus voltages to their appropriate levels (see Figure 12).
VOLTAGE TRANSLATION
The pass gate transistors of the PCA9548 are constructed such that
the VDD voltage can be used to limit the maximum voltage that will
be passed from one I2C-bus to another.

CHARACTERISTICS OF THE I2C-BUS
The I2C-bus is for 2-way, 2-line communication between different ICs
or modules. The two lines are a serial data line (SDA) and a serial
clock line (SCL). Both lines must be connected to a positive supply
via a pull-up resistor when connected to the output stages of a device.
Data transfer may be initiated only when the bus is not busy.
Start and stop conditions
Both data and clock lines remain HIGH when the bus is not busy. A
HIGH-to-LOW transition of the data line, while the clock is HIGH is
defined as the start condition (S). A LOW-to-HIGH transition of the
data line while the clock is HIGH is defined as the stop condition (P)
(see Figure 7).
Bit transfer
System configuration
One data bit is transferred during each clock pulse. The data on the
SDA line must remain stable during the HIGH period of the clock
pulse as changes in the data line at this time will be interpreted as
control signals (see Figure 6).
A device generating a message is a ‘transmitter’, a device receiving
is the ‘receiver’. The device that controls the message is the
‘master’ and the devices which are controlled by the master are the
‘slaves’ (see Figure 8).

Acknowledge
The number of data bytes transferred between the start and the stop conditions from transmitter to receiver is not limited. Each byte of eight bits
is followed by one acknowledge bit. The acknowledge bit is a HIGH level put on the bus by the transmitter whereas the master generates an
extra acknowledge related clock pulse.
A slave receiver which is addressed must generate an acknowledge after the reception of each byte. Also a master must generate an
acknowledge after the reception of each byte that has been clocked out of the slave transmitter. The device that acknowledges has to pull down
the SDA line during the acknowledge clock pulse, so that the SDA line is stable LOW during the HIGH period of the acknowledge related clock
pulse, set-up and hold times must be taken into account.
A master receiver must signal an end of data to the transmitter by not generating an acknowledge on the last byte that has been clocked out of
the slave. In this event, the transmitter must leave the data line HIGH to enable the master to generate a stop condition.

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150 °C.
