FAQs

What is PCA9548APW,118?

The PCA9548APW,118 is an I2C-bus controlled octal I2C switch with an active-low interrupt output designed by NXP Semiconductors. It allows a single master to communicate with multiple slave devices on the I2C bus by enabling or disabling individual channels.

How Does PCA9548APW,118 Work?

The PCA9548APW,118 operates by receiving I2C commands from the master device to select the desired channel for communication. The active-low interrupt output alerts the master when a channel selection changes. This switch simplifies I2C bus management in multi-device systems, providing flexibility and control for the master device.

How Many Pins does PCA9548APW,118 have and What are the Functions of the Pinout Configuration?

The PCA9548APW,118 is housed in a 24-pin TSSOP (Thin Shrink Small Outline Package) package. The pinout configuration includes:

VCC: Power supply pin.
GND: Ground pin.
SCL, SDA: I2C serial clock and data pins for communication with the master device.
EN: Enable input pin for addressing the switch.
INT: Active-low interrupt output pin.
ADDR0-ADDR2: Address selection pins for configuring the device address.
Channel 0-Channel 7: Individual channel selection pins.

What are the Pros and Cons of PCA9548APW,118?

Pros:

Multi-Channel Support: Allows a single master to communicate with multiple slave devices.
Flexible Control: Enables dynamic channel selection for I2C communication.
Interrupt Function: Provides an interrupt output to notify the master of channel changes.
Simple Integration: Integrates easily into I2C bus systems for efficient device control.
Space-Saving Package: The 24-pin TSSOP package is compact and suitable for space-constrained designs.

Cons:

Complexity: Requires proper configuration of address pins for device addressing.
Dependency on I2C Bus: Relies on the I2C bus for communication between master and slaves.
Additional Overhead: Adds an additional component for managing multiple I2C devices.

Are There Any Equivalents/Alternatives to PCA9548APW,118 for Recommendation?

The TCA9548A from Texas Instruments is a similar octal I2C switch with comparable features.
Alternatives to the PCA9548APW,118 include the LTC4316 from Analog Devices and the MAX7365 from Maxim Integrated.
